Good To Know

Q: What symptoms point to a bad camshaft position sensor? A: Look for hard starting, misfires, rough running, or a camshaft sensor fault code stored in the ECU. A failed signal can cause the engine to stall or refuse to start.

Q: Is any calibration required after fitting this sensor? A: No calibration is needed. It plugs into the factory harness as a direct replacement for the OEM 420664049 sensor on the listed models.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
