Beck/Arnley 158-0503 Throttle Position Sensor

The Beck/Arnley 158-0503 Throttle Position Sensor is a direct-replacement sensor designed to restore proper throttle monitoring and engine performance on imported vehicles. This sensor monitors the throttle valve position and sends critical data to the engine control module (ECM) to optimize fuel injection, ignition timing, and transmission shift points.

Key Features:

• Engineered to meet foreign nameplate OE specifications for form, fit, and function
• Direct replacement for worn or failed factory throttle position sensors
• Provides accurate throttle position feedback to the ECM for optimal engine performance
• Helps restore proper idle quality, acceleration response, and fuel efficiency
• Sourced from Beck/Arnley's global network of quality suppliers

A faulty throttle position sensor can cause rough idle, poor acceleration, check engine lights, and reduced fuel economy. The Beck/Arnley 158-0503 restores the precise throttle monitoring your vehicle's engine management system requires for smooth, efficient operation.
