Good To Know

Q: What symptoms point to a bad camshaft position sensor? A: Hard starting, rough idle, misfires, or a stored camshaft timing fault are typical on the 1503 engine. When the signal is lost the ECU cannot time spark correctly.

Q: Is calibration required after installing this sensor? A: Normally no calibration is required since it reads camshaft position through the trigger wheel. Clear any stored codes and verify the engine starts and idles properly.

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