Accelerator Pedal Position (APP) Sensor

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

As the accelerator pedal position changes, the sensor varies the signal voltage to the PCM which then controls the throttle position.
