A-Premium Idle Air Control Valve & Throttle Position Sensor Kit for Jeep/Dodge 1999–2004 — IAC + TPS, Hardware Included

A-Premium Idle Air Control Valve (IAC) and Throttle Position Sensor (TPS) replacement kit restores accurate idle control and throttle position feedback for compatible Jeep and Dodge V8/V6 engines.

When an engine idles rough, stalls at stop, or the check engine light flags throttle-related codes, the IAC and TPS are common wear items to inspect. This A-Premium kit pairs a four-terminal idle air control valve with a three-terminal throttle position sensor engineered to fit specific Jeep Grand Cherokee, Liberty, Dodge Dakota, Durango and Ram 1500 models from the 1999–2004 era. Each part is supplied with mounting hardware and O-rings where required, letting you replace both sensors in one service visit without hunting for extra fasteners.

How will replacing the IAC and TPS improve engine idle and drivability?

Swapping worn or faulty sensors returns the engine computer’s ability to regulate air bypass and measure throttle angle accurately, which reduces erratic idle and helps prevent stalling. Improved sensor readings also stabilize idle under load changes like A/C engagement or electrical loads.

• Restores precise idle control by regulating bypass airflow
• Provides accurate throttle position feedback to the ECU
• Includes new mounting bolts and O-rings for leak-free installation
• Fits exact OEM-style connectors for plug-and-play replacement
