Specs At A Glance

Good To Know

Q: What happens if the camshaft position sensor fails? A: A failed sensor can cause hard starting, misfires, or a no-start condition because the ECU loses camshaft timing data. Replacing it with this direct-fit unit restores the signal.

Q: Does this sensor need programming after installation? A: No programming is required on this application; the sensor plugs into the factory connector and works with the existing ECU calibration. Clear any stored fault codes after fitting.

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