Throttle Position (TP) Sensor: 2.5L
- Turn ignition off. Remove TP sensor connector. Install a 0.006" (.15 mm) feeler gauge between throttle plate stop screw and throttle lever. See Figure
.
- Connect ohmmeter leads to terminals IDL and GND. See Fig 1
. Loosen TP sensor mounting screws. Continuity should be present. Install a 0.020" (.50 mm) feeler gauge between throttle plate stop screw and throttle lever. Continuity should not be present. If continuity is not as specified, go to next step.
- Install Breakout Box (014-00322) and Adapter (T92C-6000-AH) between Powertrain Control Module (PCM) and PCM wiring harness connector. Turn ignition on. Measure voltage between breakout box test pin No. 47 and ground.
- With throttle valve closed, voltage should be 0.1-1.0 volt. With throttle valve fully open, voltage should be 3.1-4.4 volts. If voltage is not as specified, loosen TP sensor mounting bolts.
- Rotate TP sensor until voltmeter reads 0.1-1.0 volt with throttle valve fully closed and 3.1-4.4 volts with throttle valve fully open. Replace TP sensor if specified voltages cannot be obtained.
