Beck/Arnley 158-0864 Throttle Position Sensor

The Beck/Arnley 158-0864 Throttle Position Sensor is a direct replacement component designed to monitor the position of the throttle valve in your vehicle's throttle body. This sensor sends critical position data to the engine control module (ECM), allowing the computer to optimize fuel delivery, ignition timing, and transmission shift points based on throttle input.

Key Features:

• Engineered to meet or exceed OE specifications for form, fit, and function
• Direct-fit replacement for worn or failed factory throttle position sensors
• Provides accurate throttle angle readings for optimal engine performance
• Helps ensure proper fuel economy and smooth acceleration
• Manufactured to foreign nameplate OE quality standards

A failing throttle position sensor can cause symptoms including rough idle, hesitation during acceleration, poor fuel economy, and illuminated check engine lights. The Beck/Arnley 158-0864 restores proper communication between your throttle and engine management system for reliable performance.
