Detailed Product Description

The Dorman 977-401 throttle position sensor features a robust aluminum and PBT construction, providing strength and resistance to heat and wear. It mounts directly on the throttle body, ensuring accurate measurement of throttle plate position. The sensor uses a blade-type terminal with three electrical connections via a connector, facilitating straightforward integration with the vehicle’s wiring harness. Its non-adjustable design maintains factory calibration, reducing the need for manual tuning. The black finish adds an extra layer of protection against environmental factors.

Compatible Vehicles and Applications

This throttle position sensor is compatible with select Dodge and Plymouth vehicles, specifically the Breeze, Neon, and Stratus models. It is engineered to meet the emission control requirements of these vehicles, helping to maintain proper engine performance and fuel efficiency.

• Helps resolve throttle response issues
• Addresses engine stalling or hesitation during acceleration
• Corrects erratic idle problems related to throttle position
• Supports emission control system functionality
• Prevents check engine light triggers related to throttle sensor faults

Installation Notes and Tips

Installation requires mounting the sensor directly on the throttle body using existing hardware. Ensure the electrical connector is securely attached to the sensor’s blade terminals.
