- 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 passes electrical signals to your engine’s throttle, which controls how quickly or slowly it moves based on the engagement of the accelerator pedal. If the gas pedal is pressed down, the Accelerator Pedal Sensor instantly tells the throttle to open wider, allowing more air to enter the engine. When you release the accelerator, the Accelerator Pedal Sensor notifies the throttle to close (the amount it closes will depend on the position of the pedal), thereby slowing down your Nissan.
Before this electronic system was created, the communication between the accelerator and the throttle was entirely mechanical. In older car models, a strong wire ran from the acceleration pedal to a valve that would pull and push the throttle open or closed, depending on how hard the pedal was pushed. These days, vehicles use the Accelerator Pedal Sensor for maximum performance.
Signs that your Nissan Accelerator Pedal Sensor should be replaced can include: delayed acceleration or deceleration when engaging or releasing the gas pedal, a decline in fuel efficiency, or an illuminated engine light on your Nissan's dash.
If you notice one or more of those signs, visit your nearby Nissan dealer or service site as soon as possible and ask about your Accelerator Pedal Sensor. A misfiring or broken Accelerator Pedal Sensor can impact your engine’s performance and efficiency. A professional Nissan technician can install a brand new sensor and ensure your Nissan is in tip-top shape.
