Specs At A Glance

Good To Know

Q: How do I know the camshaft position sensor needs replacing? A: Common signs include hard starting, misfires, rough idle, or a stored fault code for camshaft signal loss. Testing signal output at the connector confirms whether the sensor or wiring is at fault.

Q: Does this sensor require programming after installation? A: No, this camshaft position sensor is a plug-and-play replacement and does not need calibration. Clear any stored fault codes after installation and verify the engine runs cleanly.

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