Airtex 5S15831 Accelerator Pedal Position Sensor

The Airtex 5S15831 is a replacement Accelerator Pedal Position (APP) Sensor designed to restore precise throttle input communication between the accelerator pedal and the engine control module (ECM). This sensor monitors the position of the accelerator pedal and transmits the corresponding signal to the ECM, which in turn controls throttle body opening and fuel delivery.

Key Features:

• Direct OE replacement — engineered to match original equipment specifications
• Restores accurate pedal position feedback to the engine control module
• Helps eliminate hesitation, surging, or unresponsive throttle behavior
• Manufactured by Airtex Automotive Division, a trusted name in OE-quality replacement sensors
• Designed for straightforward, plug-and-play installation using existing wiring harness connectors

A faulty accelerator pedal position sensor can trigger a check engine light, cause erratic throttle response, or put the vehicle into a reduced-power (limp) mode. Replacing the sensor with a quality unit like the Airtex 5S15831 helps ensure smooth, reliable throttle operation and proper engine management system function.
