Specs At A Glance

Good To Know

Q: What happens if this sensor fails? A: A failed camshaft position sensor often causes hard starting, misfires, or a no-start condition because the ECU loses its timing reference. Replacing it restores the signal the engine needs to run correctly.

Q: Do I need any special tools to install it? A: Basic hand tools are usually enough since the sensor mounts in the factory location and connects to the existing harness. Disconnecting the battery before the swap is a sensible precaution.

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