Nissan P0335 is a diagnostic trouble code related to the crankshaft position sensor circuit. The code indicates that the engine control system has detected a problem with the crankshaft position signal during engine operation or starting. However, P0335 does not automatically mean that the crankshaft position sensor itself has failed. The fault can also involve the wiring, electrical connector, signal related components, or other parts of the circuit.
A Nissan with P0335 may experience hard starting, intermittent starting, engine stalling, or a no start condition. The correct repair therefore depends on identifying why the expected crankshaft position signal is missing or incorrect. Replacing the sensor without checking the circuit can leave the underlying problem unresolved.
This guide explains what Nissan P0335 means, which symptoms to look for, what causes the code, and how to diagnose the crankshaft position sensor circuit before replacing parts. It also explains how to repair the confirmed fault and verify that P0335 has been properly resolved.
What Does Nissan P0335 Mean?
Nissan P0335 indicates a problem with the crankshaft position sensor circuit. The crankshaft position sensor, also called the CKP sensor or POS sensor in Nissan service information, sends crankshaft position and rotation data to the engine control system. The ECM uses this signal during engine control. When the ECM cannot detect the expected signal, it can store P0335.
P0335 does not automatically mean that the crankshaft position sensor has failed. The problem can also involve the wiring, electrical connector, or signal plate. Nissan diagnostic procedures check the complete circuit before technicians replace a component. This approach helps identify the actual source of the fault.
The crankshaft position signal plays an important role during engine starting and operation. The engine control system needs accurate crankshaft information to manage engine functions. A faulty signal can therefore cause starting or running problems. The exact symptoms depend on the condition of the fault. An intermittent problem can produce different symptoms from a complete loss of signal.
The correct diagnostic process starts by confirming P0335. The next step involves checking the sensor and its circuit. Technicians should inspect the wiring and connector for damage or poor contact. They should also check the relevant signal components. This process helps determine whether the sensor or another part of the circuit causes the problem.
What Symptoms Can Nissan P0335 Cause?
Nissan P0335 can cause starting problems, engine stalling, and a Check Engine Light. The exact symptoms depend on how the crankshaft position sensor circuit fails. A complete loss of the crankshaft position signal can create more severe starting problems than an intermittent signal fault.
A no start condition is one of the most important symptoms to watch for. The engine may crank but fail to start when the control system cannot receive the crankshaft position information it needs. Some vehicles may also develop hard or intermittent starting. In these cases, the engine may start normally at one time and fail to start at another. The intermittent nature of the fault can make diagnosis more difficult.
Engine stalling can also occur when the crankshaft position signal becomes unreliable during operation. The engine control system relies on crankshaft position information while the engine runs. If the signal disappears or becomes incorrect, the vehicle may lose normal engine operation. A vehicle that stalls unexpectedly requires prompt diagnosis because the problem can return without warning.
The Check Engine Light can accompany P0335 when the engine control system detects the fault and stores the diagnostic trouble code. A scan tool can confirm the stored code and reveal additional codes that may help identify the cause. Nissan diagnostic information also points to the crankshaft position sensor circuit, wiring, connectors, and signal related components as possible areas to inspect.
What Causes Nissan P0335?
Nissan P0335 can result from a faulty crankshaft position sensor, damaged wiring, a poor electrical connection, or a problem with the signal plate. The diagnostic code points to the crankshaft position sensor circuit, so the correct diagnosis must examine the complete circuit rather than assume that the sensor has failed.
A faulty crankshaft position sensor can prevent the engine control system from receiving the correct crankshaft position signal. Sensor failure can affect engine starting and operation because the ECM needs crankshaft information to control engine functions. However, the presence of P0335 alone does not prove that the sensor caused the fault.
Damaged wiring can also cause P0335. An open circuit or short circuit can interrupt the signal between the crankshaft position sensor and the engine control system. Physical damage, poor connections, or other wiring faults can create the same diagnostic code even when the sensor itself works correctly.
A damaged or poorly connected electrical connector can create another source of the problem. Loose terminals, damaged wiring near the connector, or poor electrical contact can interrupt the crankshaft position signal. These faults can also create intermittent symptoms that make the vehicle start or run normally at one time and develop a problem later.
The signal plate can also contribute to P0335. The crankshaft position sensor depends on the correct signal source to provide usable crankshaft information. Nissan diagnostic procedures therefore include the sensor circuit and signal plate when technicians investigate the code.
An ECM related problem requires careful diagnosis rather than immediate replacement. Technicians should first check the sensor, wiring, connectors, and relevant signal components. This approach helps identify the confirmed cause and prevents unnecessary parts replacement.
How Do You Diagnose Nissan P0335?
Diagnose Nissan P0335 by confirming the code, checking related codes, inspecting the crankshaft position sensor circuit, and testing the components that can interrupt the crankshaft position signal. Start with the diagnostic trouble code rather than replacing the sensor immediately. Nissan service procedures identify the sensor circuit, wiring, connectors, and signal plate as key areas in the diagnostic process.
What Should You Check Before Replacing the Crankshaft Position Sensor?
First, confirm that the scan tool actually shows P0335 and record any additional diagnostic codes. Additional codes can provide useful information about related engine control problems. Next, check whether the engine cranks normally and note whether the starting or stalling problem occurs consistently or intermittently. These details help define the fault before component testing begins.
Next, inspect the crankshaft position sensor and its electrical connector. Look for visible damage, loose connections, damaged terminals, or wiring problems near the sensor. A connector problem can interrupt the signal even when the sensor itself remains functional. Nissan diagnostic information specifically includes the harness and connector when checking the crankshaft position sensor circuit.
Then, test the sensor circuit according to the service procedure for the specific Nissan model and engine. Check the relevant wiring and electrical connections before deciding that the sensor has failed. The exact voltage, resistance, terminal, and signal specifications depend on the Nissan engine and sensor design. The available source material does not provide one universal specification for every Nissan model, so those values should come from the applicable factory service information.
Finally, verify the crankshaft position signal and inspect the signal plate when the basic circuit checks do not identify the fault. This approach separates a sensor problem from a wiring problem or another signal related fault. It also reduces unnecessary parts replacement and gives the repair a clear diagnostic basis.
How Do You Fix Nissan P0335?
Fix Nissan P0335 by repairing or replacing the component that causes the crankshaft position sensor circuit fault. The correct repair depends on the diagnostic result. A faulty sensor requires a different repair from damaged wiring, a poor connector, or a signal plate problem. Nissan diagnostic procedures therefore support a component based repair rather than replacing the sensor automatically.
Replace the crankshaft position sensor when testing confirms that the sensor has failed. Use the correct sensor for the specific Nissan model and engine. After replacement, reconnect the sensor correctly and verify that the circuit operates as expected. Replacing the sensor without confirming a sensor fault can leave P0335 unresolved when another part of the circuit causes the problem.
Repair damaged wiring when the diagnostic test identifies an open circuit, short circuit, or other wiring fault. Restore the electrical connection according to the applicable Nissan repair procedure. Pay particular attention to the wiring near the sensor and connector because damage in these areas can interrupt the crankshaft position signal.
Repair the electrical connector when poor contact or connector damage causes the fault. Check the terminals and wiring connection before returning the vehicle to service. A loose or damaged connection can create an intermittent P0335 that appears and disappears as the vehicle operates.
Inspect the signal plate when the sensor and circuit checks do not identify the cause. Nissan diagnostic information includes the signal plate among the components that technicians may need to check when diagnosing the crankshaft position sensor circuit.
Do not replace the ECM based only on the P0335 code. Check the sensor, wiring, connector, and signal related components first. This diagnostic sequence helps identify the actual fault and prevents unnecessary component replacement.
Can You Drive a Nissan With P0335?
Driving with Nissan P0335 depends on how the vehicle behaves and whether the crankshaft position signal remains reliable. A vehicle may continue to run when the fault is intermittent, but the problem can also cause hard starting, a no start condition, or engine stalling. These symptoms make the vehicle less predictable and require proper diagnosis.
Avoid continuing to drive the vehicle when P0335 causes repeated engine stalling or starting problems. An unreliable crankshaft position signal can affect engine operation because the engine control system depends on crankshaft position information. If the engine stalls while driving, the vehicle can lose normal propulsion and create a safety concern. The available source material identifies engine stalling and starting problems as possible effects of a crankshaft position sensor circuit fault.
A vehicle that starts normally and shows no noticeable drivability problem still needs diagnosis. The absence of severe symptoms does not identify the cause of P0335. The fault can involve the crankshaft position sensor, wiring, connector, or signal plate. Checking the complete circuit helps determine whether the problem needs immediate repair or whether the vehicle has an intermittent fault that requires further testing.
Do not judge the seriousness of P0335 from the warning light alone. Check the stored code and related symptoms together. If the vehicle develops a no start condition, repeated stalling, or worsening starting problems, diagnose the fault before relying on the vehicle for normal driving.
How Do You Clear and Verify Nissan P0335 After a Repair?
Clear Nissan P0335 after repairing the confirmed cause, then verify that the code does not return. Clearing the diagnostic trouble code removes the stored fault from the control system, but it does not prove that the underlying problem has been fixed. A proper repair requires both code clearing and system verification.
Use an appropriate diagnostic scan tool to clear the stored P0335 code after completing the repair. Start the engine and check whether it starts normally. If the original problem involved hard starting, intermittent starting, or stalling, confirm that the same symptom no longer occurs. Nissan diagnostic procedures use fault confirmation and circuit checks to determine whether the crankshaft position sensor system operates correctly.
Scan the vehicle again after the repair to check whether P0335 returns. A returning code indicates that the control system still detects a problem. If P0335 returns, continue the diagnosis instead of repeatedly clearing the code. Recheck the sensor, wiring, connector, and relevant signal components based on the results of the previous tests.
Check for additional diagnostic trouble codes as part of the verification process. Another stored code can point to a related engine control problem and change the diagnostic direction. The absence of P0335 after a restart provides useful evidence, but the original symptoms should also remain resolved.
A successful repair should restore normal starting and engine operation while preventing P0335 from returning. The final verification should therefore connect the diagnostic code with the original vehicle symptoms. This approach confirms that the repair addressed the actual fault rather than simply removing the warning code.
What Should You Do When Your Nissan Has P0335?
Start by diagnosing the Nissan P0335 circuit before replacing any component. The code points to a problem with the crankshaft position sensor circuit, but the sensor itself may not cause the fault. Wiring, electrical connectors, and the signal plate can also contribute to the problem.
Confirm the code, identify the symptoms, inspect the circuit, and test the relevant components. This diagnostic sequence helps separate a faulty crankshaft position sensor from wiring or connection problems. It also prevents unnecessary parts replacement. The exact electrical specifications and testing procedure should follow the service information for the specific Nissan model and engine.
Repair the confirmed cause and then verify the result. Clear the stored P0335 code, restart the vehicle, check for returning diagnostic codes, and confirm that the original starting or stalling symptoms have disappeared. Clearing the code alone does not prove that the repair solved the underlying problem.
A proper diagnosis therefore follows a clear path: confirm P0335, identify the symptoms, inspect the crankshaft position sensor circuit, locate the failed component, complete the repair, and verify normal operation. This approach gives the vehicle a better chance of receiving the correct repair the first time.
