Control
Models before 1988
1. The throttle position sensor is located on the throttle body. Disconnect the sensor electrical connector.
2. Measure the resistance between the black-brown and yellow-red contacts. Compare the data with the values given in the specification.
3. If the resistance is different from the given one, loosen the fastening screw and adjust the position of the sensor. Measure the resistance again (if the set screw has a shear head, see step 6). If the resistance value does not recover, replace the sensor.
Models since 1988
4. Checking the sensor and its circuits is carried out only at a service station.
Replacement
5. Disconnect the wires from the sensor.
6. Remove the mounting bolts and the holder. If the bolts are shear-head type, drill a small hole in the center and remove the bolt with a thread extractor. This procedure is easier if the valve body is removed from the vehicle (see Chapter 4).
7. Remove the sensor from the housing.
8. Insert the sensor (with a new gasket) into the damper housing, aligning the sensor shaft and damper shaft. On pre-1988 models, adjust the sensor by rotating the damper counter-clockwise and tighten the bolts gently but securely.
9. Checking the sensor resistance (see steps 1-3), turning the sensor to obtain the required resistance (only for models before 1988).
10. Tighten the bolts. If shear-off head bolts are used, tighten until the head shears off.
11. Connect the electrical connector.
