• Communicates between your gas pedal and the throttle
• Notifies the throttle when to accelerate or decelerate
• Replacement requires an experienced technician

The Accelerator Pedal Sensor in your INFINITI transmits electronic signals to the throttle, which determines how fast it moves based on the position of the gas pedal. When the accelerator pedal is pressed down, the Accelerator Pedal Sensor instantly signals the throttle to open further, allowing more air to enter the engine. As you put less pressure on the gas pedal, the Accelerator Pedal Sensor notifies the throttle to close incrementally (how much it closes depends on the pedal position), which then decreases the rate of acceleration in your INFINITI.

Before this technological advancement, the communication between the gas pedal and throttle was a mechanical system. In older cars, an internal wire went from the accelerator to a valve that would push or pull the throttle open and shut, depending upon how far the pedal was depressed. Now, vehicles are made with an electronic Accelerator Pedal Sensor for increased efficiency and reliability.

Symptoms that indicate your Accelerator Pedal Sensor should be replaced can vary, but commonly include: delayed acceleration or deceleration when pressing or backing away from the accelerator, a decline in gas mileage, or an engine warning light on the dash panel in your INFINITI.

If your INFINITI is showing any of the above signs, stop by your local INFINITI service center ASAP and ask the pros about a replacement Accelerator Pedal Sensor. A malfunctioning Accelerator Pedal Sensor may hurt your engine’s performance and efficiency. A qualified INFINITI service technician can install a brand new sensor and get your INFINITI in tip-top shape.
