Infiniti car, truck, or SUV owners have become used to a certain level of sporty handling when driving their QX4 around town.

When your Infiniti QX4 was born, it was destined for a driver who wants Japanese engineering in their automobile.
Your fuel-injected engine requires constant communication between the engine control module and the throttle position sensor to maintain the best balance between power and gas mileage. 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. At wide open throttle it may downshift and flood the fuel injectors for more power, or reduce fuel consumption when you let off the accelerator. Either way, the Infiniti QX4 throttle position sensor is absolutely critical to your engine performance.
