Specs At A Glance

Good To Know

Q: Will this sensor clear a camshaft position fault code? A: Replacing a failed pickup commonly resolves camshaft position codes, but the fault should be cleared and the wiring checked for damage before assuming the repair is complete.

Q: Do I need to reprogram anything after installing it? A: No programming is needed; the ECU reads the camshaft position signal as soon as the sensor is connected and the engine turns over.

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