When your Infiniti QX4 left the factory, it was destined for a driver who prioritizes Japanese engineering in their automobile. Obviously, you didn't buy your QX4 unless you understood you would be getting long-lasting quality and a trusted brand both rolled up into one automobile. While it's not hard to buy replacement parts for Infiniti vehicles, these days only the absolute best are required to repair your car or truck. Anyone who operates a Infiniti knows that when it comes to fixing their car, truck, or SUV only the most superior replacement parts will do.
In order to achieve an optimum balance between fuel economy and horsepower, your fuel-injected engine requires constant communication between its engine control unit and the throttle position sensor. The throttle position sensor on your Infiniti QX4 detects the opening and closing of the butterfly plates inside the throttle body and reports this to the ECU. It may lower the amount of fuel being sent to the injectors, or it may downshift the transmission and give you a boost of power. Either way, the Infiniti QX4 throttle position sensor is absolutely critical to your engine performance.
