Good To Know

Q: How do I know if my camshaft position sensor has failed? A: Common signs include hard starting, rough idle, misfires, and stored timing-related fault codes. A scan tool reading live camshaft signal data can confirm the diagnosis.

Q: Is this sensor a direct replacement for the original? A: It is built to match OEM part number 420664049 and connects to the factory harness without modification. Always verify your engine serial number before ordering.

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