2003 Nissan Sentra P0335 Code: Check Engine Light On After Crankshaft Sensor Replacement
The 'Check Engine' light has been continuously coming on in my 2003 Nissan Sentra SE-R Spec V with the 2.5L QR25DE 4-cylinder engine. Every time I scan the system, I'm getting the P033-5 code. I recently replaced the crankshaft position sensor last month, but the issue persists and the check engine light remains on. There are no noticeable performance issues other than intermittent stalling and difficulty restarting, especially after the car has been warmed up. I'm at a loss as to what could be causing this recurring fault. Any insights or troubleshooting steps would be greatly appreciated.
P0335 indicates a crankshaft position sensor A circuit issue. P0462 shows a fuel level sensor circuit low. These two codes are commonly seen together and can result in symptoms such as hard stalling, difficulty restarting, and prolonged warm-up periods. The vehicle may stall unexpectedly during operation or after being idle for some time.
