The Dorman 977-519 Throttle Position Sensor is a direct-fit replacement part engineered to restore accurate throttle position readings on compatible 1997–2001 Dodge Dakota and Jeep models.

This throttle position sensor (TPS) replaces the original unit on specified Dodge and Jeep vehicles and is built to provide dependable operation under normal driving conditions. Designed to match the factory mounting and electrical connections, the part aims to make swapping a worn or malfunctioning sensor straightforward. Before purchasing, confirm fitment by entering your vehicle’s make, model and trim into the garage tool.

How does this TPS restore driveability?

Replacing a faulty TPS can return smooth acceleration response and more consistent idling by sending correct throttle position data to the engine control module. The Dorman unit replicates the original sensor’s electrical characteristics so the engine management system receives expected signals.

• Restores proper throttle angle feedback to the ECU.
• Reduces hesitation or surging caused by erratic voltage readings.
• Matches OEM mounting points and connector style for easier installation.

Will this sensor fit my vehicle?

The Dorman 977-519 is compatible with a defined list of model years and trims; always verify your vehicle’s specific fitment before ordering. Use the site’s garage tool to check your exact make, model and trim to ensure correct application.

• Compatible models include Dodge Dakota (1997–2001).
• Compatible Jeep models include Cherokee, Grand Cherokee and Wrangler (1998–2001).
• Input precise trim level in the garage tool for final confirmation.

What should I know about installation and testing?

Installation typically requires removing the throttle body access panel or air intake components to reach the sensor, then unbolting the old unit and swapping the connector. After replacement, a quick wiring and output check with a multimeter or a diagnostic scan can confirm correct operation before road testing.

• Basic hand tools and safety precautions are usually sufficient.
• Verify connector seating and wiring integrity before powering the vehicle.
• Perform a live signal or resistance check to confirm expected sensor output.

Why choose this Dorman part over a used sensor?

This new Dorman TPS is manufactured from fresh components to avoid problems tied to wear, contamination, or degradation that affect reused parts. Buying a new replacement reduces the risk of early failure and removes the uncertainty of unknown service history.

• New components avoid previous wear or electrical fatigue common in used sensors.
• Designed to match original fit and function for a straightforward swap.
• Supported by Dorman’s product team with decades of automotive parts experience.
