Specs At A Glance

Good To Know

Q: Does this sensor require calibration after installation? A: No calibration is needed; the ECU reads camshaft position automatically once the sensor is connected. Clear any stored codes and run the engine to verify smooth operation.

Q: What symptoms point to a bad camshaft position sensor? A: Hard starting, stalling, misfires, and a check engine light are typical indicators. Confirming with a resistance and signal test before replacement saves time and avoids unnecessary parts swaps.

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