Throttle Position (TP) Sensor
RH side of TBI (Throttle Body Injection)
Testing and Inspection:
This check should be performed when TP sensor attaching parts have been replaced. A Tech 1 scan tool can be used to read the TP sensor output voltage, or:
Connect digital voltmeter J 39200 or equivalent, from TP sensor connector terminal "B" (BLK wire) to terminal "C" (DK BLU wire). Jumpers for terminal access can be made using terminals "1214836" and "12014837".
With ignition "ON," engine stopped, the TP sensor voltage should be less than .85 volt if more than 85 volt verify free throttle movement. If still more than .85 volt, replace TP sensor.
Remove the voltmeter and jumpers, reconnect the TP sensor connector to the sensor.
