Throttle Position (TP) Sensor

Disconnect negative battery cable and TP sensor connector. See Fig 1 . Using ohmmeter, check resistance between indicated terminals. See THROTTLE POSITION (TP) SENSOR RESISTANCE table.

If resistance is not as specified, adjust the TP sensor. See the ADJUSTMENTS article. If resistance is not as specified after adjustment, replace TP sensor. For further diagnostic procedures, see the TESTS W/CODES article.

THROTTLE POSITION (TP) SENSOR RESISTANCE

Application	Ohms
Between Terminals "A" & "C"	100-100,000
Between Terminals "A" & "D"	2870-5330

Disconnect negative battery cable. Remove instrument cluster. Connect ohmmeter between RSW and GND terminals on back of instrument cluster. Insert screwdriver into speedometer cable connector. Rotate screwdriver. See Fig 2 .
Ohmmeter reading should alternate between zero and infinity 4 times for each revolution of speedometer cable. Replace speedometer if VSS does not test as described.
