Good To Know

Q: Will this sensor fix a rough-running engine? A: If the camshaft sensor is faulty, replacing it can restore proper timing and smooth out performance. Always check for stored fault codes first to confirm the sensor is the cause.

Q: Does this sensor require any programming? A: No programming is needed; it connects directly to the factory harness and works with the existing ECU. Simply install and clear any old fault codes.

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