Examination
Checking the resistance between the corresponding terminals of the throttle position sensor on four-cylinder engines
Checking the resistance between the corresponding terminals of the throttle position sensor connector on six-cylinder engines
1. Disconnect the electrical connector from the throttle position sensor (TPS) and apply vacuum to the throttle positioner.
2. Install a 0.7mm feeler gauge between the idle speed adjustment screw and the stop.
3. Using an ohmmeter, measure the resistance between the corresponding pairs of contacts on the electrical connector (see Fig. Checking the resistance between the corresponding terminals of the throttle position sensor on four-cylinder engines and Fig. Checking the resistance between the corresponding terminals of the throttle position sensor connector on six-cylinder engines).
If the measured resistance differs from the required values, install a 0.7 mm thick feeler gauge between the idle speed adjustment screw and the stop and connect the ohmmeter to the IGL and E2 terminals. Loosen the throttle position sensor mounting screws and slowly rotate the sensor clockwise until the ohmmeter shows infinity.
4. Tighten the throttle position sensor mounting screws, install the probe and re-measure the resistance between the corresponding terminals.
Replacement
If adjusting the sensor does not bring positive results, unscrew the sensor mounting screws and replace the sensor with a new one.
