Throttle Position Sensor: Adjustments
NOTE: Before attempting to adjust the Throttle Sensor, make certain the idle speed and ignition timing are correctly adjusted. See this section for the
proper procedures.
1.
Verify the following conditions:
a. Engine fully warmed up. (185 - 205°F)
b. All lights, engine cooling fan and accessories "off".
c. Transmission in P or N.
d. Steering wheel in the straight ahead position (models with power steering only)
Accelerator Cable Adjustment
2.
Verify that the throttle cable has enough slack that it is not holding the throttle open in any way. Loosen the adjustment bolts for the throttle cable
if necessary.
3.
Using a high-impedance digital voltmeter, carefully back probe the throttle position connector into terminals #2 and #4. Refer to the connector in
the image.
Throttle Position Sensor (TPS)
4.
Turn the key to the ON position.
5.
Check the output voltage.
Voltage
0.48 - 0.52 volts
If the voltage is not as specified, adjust the TPS by loosening the mounting screws and rotating the sensor.
NOTE: Clockwise rotation of the sensor increases the voltage output while counter-clockwise rotation reduces voltage.
6.
Tighten the sensor set screws securely.
7.
Turn the ignition switch OFF.
8.
Disconnect the battery for at least ten seconds to clear any stored trouble codes.
