Translate the driver's pedal input into a precise electronic signal with the Standard Ignition Accelerator Pedal Sensor APS311. It drops in as a direct-fit replacement for the listed applications: the 2009 Buick Allure, 2009 Buick LaCrosse, 2009-2013 Chevrolet Impala, and 2014-2016 Chevrolet Impala Limited.
On these drive-by-wire vehicles, the accelerator pedal sensor reports pedal position to the engine control module, which commands the electronic throttle accordingly. When the original sensor fails, the mechanical throttle cable it replaces no longer exists, so an accurate signal is essential to how the engine responds to your foot.
- Electronic pedal-position signal: reports how far the accelerator pedal is pressed so the control module can manage throttle response.
- Direct-fit design: intended to install in place of the original sensor on the listed applications.
- Replacement part: intended to replace a worn or failed original accelerator pedal sensor.
Signs the sensor may need replacing include hesitation, an unresponsive or erratic pedal, reduced-power mode, or a stored accelerator-pedal-position trouble code. Because those symptoms can have other causes, diagnose the fault first; if the accelerator pedal sensor is confirmed as the cause, this unit replaces it.
Manufacturer part number APS311.
