Airtex 5S14843 Accelerator Pedal Position Sensor

The Airtex 5S14843 is a direct-fit accelerator pedal position sensor (APPS) designed to restore proper throttle response and drivability. This electronic sensor monitors the position of the accelerator pedal and transmits a precise signal to the engine control module (ECM), allowing the vehicle's drive-by-wire throttle system to respond accurately to driver input.

Key Features:

• Direct OE replacement — no modifications required for installation
• Engineered to meet or exceed original equipment specifications
• Provides accurate pedal position signal to the ECM/PCM for precise throttle control
• Helps resolve symptoms such as hesitation, surging, rough idle, or illuminated check engine light related to pedal sensor failure
• Manufactured by Airtex Automotive Division, a trusted name in engine management and fuel system components

A faulty accelerator pedal sensor can cause drivability issues including unresponsive throttle, erratic acceleration, or limp mode activation. The Airtex 5S14843 restores reliable, factory-level performance and is built for long-term durability in demanding automotive environments.
