It sends calibrated vibration signals to the engine control unit (ECU) so the computer can adjust ignition timing and protect the engine from pre-ignition events. The part is produced to meet or exceed OEM specifications and ships with a 12‑month warranty.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engines will this sensor kit fit?\u003c\/h3\u003e\n\u003cp\u003eThis OYEAUTO assembly fits many GM models and specific RPO engine codes. It supports several Chevrolet, GMC and Cadillac vehicles equipped with 4.8L, 5.3L, 5.7L and 6.0L engines produced in model years roughly 1999–2007.
