- 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 Nissan transmits electrical cues to the throttle, directing it on how fast or slow to go based on how your gas pedal is engaged. When the accelerator pedal is pressed down, the Accelerator Pedal Sensor instantly notifies the throttle to open wider and allow larger amounts of air and fuel into the engine. When you release the accelerator pedal, the Accelerator Pedal Sensor signals the throttle to close (the amount it closes is based on the position of the pedal), which slows acceleration in your Nissan.
Before the existence of the Accelerator Pedal Sensor, the correspondence between the accelerator and the throttle was a mechanical system. In older cars, a wire connected the acceleration pedal to a component that would move the throttle open and shut, depending on the position of the gas pedal. Now, vehicles are made with an electronic Accelerator Pedal Sensor for maximum performance.
The signs that your Accelerator Pedal Sensor should be replaced can include: inconsistent acceleration and deceleration when pressing or releasing the acceleration pedal, diminished fuel efficiency, or an engine warning light on your Nissan dashboard.
If your Nissan is showing any of these symptoms, visit your nearby Nissan authorized service center as soon as you can and ask about your Accelerator Pedal Sensor. A damaged Accelerator Pedal Sensor can impact your engine’s performance and efficiency. An experienced technician can help you with a brand new sensor and ensure your Nissan is in tip-top shape.
