Infiniti Error Code P0335: How to Fix It

Q: Can I drive my Infiniti with error code P0335?

You should not drive with P0335 as it can cause engine stalling, poor performance, or prevent starting. The engine may run in limp mode or shut down unexpectedly, creating a safety hazard.

Q: How much does it cost to fix P0335 on an Infiniti?

DIY repairs typically cost $50-150 for a new sensor. Professional diagnosis and repair can range from $200-500 depending on labor rates and whether wiring repairs are needed.

Q: What causes a crankshaft position sensor to fail?

Common causes include normal wear from heat cycles, oil contamination, physical damage from debris, or electrical issues like corroded connections and damaged wiring.

Q: How do I know if it's the sensor or the wiring?

Test the sensor resistance and check for proper voltage supply at the connector. If the sensor tests good but there's no reference voltage, the problem is likely in the wiring or ECM.

Q: Will P0335 cause my Infiniti to not start?

Yes, P0335 can prevent starting since the ECM needs crankshaft position data to time ignition and fuel injection. The engine may crank but not fire, or may start briefly then stall.

Abstract

Error code P0335 indicates a malfunction in your Infiniti's crankshaft position sensor circuit. This sensor tells the engine control module when to fire the spark plugs and fuel injectors. When it fails, your engine may not start, stall randomly, or run poorly.
