TPS Throttle Position Sensor & IAC Idle Speed Air Control Valve for Ford F-250
This TPS throttle position sensor and IAC idle speed air control valve set is designed for Ford F-250 pickup trucks, restoring accurate throttle response and stable idle control. The TPS throttle position sensor monitors throttle blade position while the IAC idle speed air control valve regulates bypass air to maintain correct idle speed, replacing worn components to fix stalling and rough running.
Overview
This direct-replacement kit includes a TPS throttle position sensor and an IAC idle speed air control valve for Ford F-250 trucks. The TPS throttle position sensor provides real-time throttle position data to the powertrain control module, while the IAC idle speed air control valve controls idle air flow to prevent stalling. This pair resolves common issues like idle surge, stalling, and poor throttle response in Ford F-250 work trucks.

Good To Know
Q: What symptoms indicate a failing TPS or IAC on my F-250? A: Look for rough idle, stalling when coming to a stop, delayed throttle response, or diagnostic trouble codes P0122 or P0505. Replacing both as a set ensures consistent idle control.
Q: Is this kit compatible with gasoline engines only? A: This TPS and IAC set is intended for gasoline-powered Ford F-250 trucks; it does not fit diesel engines. Verify your engine type and model year before purchasing.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
