Specs At A Glance

Good To Know

Q: Will this sensor need programming after installation? A: No, a camshaft position sensor is a plug-and-play component and does not require reprogramming. Install it, clear any stored fault codes, and verify timing signal with a diagnostic scan tool.

Q: What symptoms point to a faulty camshaft position sensor? A: Common signs include hard starting, rough idle, stalling, and a check engine light with a camshaft position code. Replacing the sensor often resolves these issues on the 1503 engine.

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