Its purpose is to relay this information to the engine control unit (ECU), which optimizes the fuel-air mixture for improved engine performance and fuel efficiency. As an original equipment manufacturer's (OEM) product, this part ensures high quality and matches the part sold at the new car dealership. This is a brand new genuine part in OEM manufacturer's packaging and is not an aftermarket product.
