Steps | _ Key Off, wait 10 seconds. Disconnect Throttle Position Sensor harness connector
_ Disconnect processor 60 pin connector. Inspect for damaged pins, corrosion, loose wires, etc. Service as necessary. _ DVOM on 200,000 ohm scale _ Measure resistance between Throttle Position Sensor SIGNAL at the Throttle Position Sensor vehicle harness connector and Test Pin 46 at the breakout box and between Throttle Position Sensor SIGNAL at Throttle Position Sensor vehicle harness connector and ground |
Result | Are all resistances greater than 10,000 ohms? |
Direction | NO
Service short circuit. Remove breakout box. Reconnect processor and Throttle Position Sensor. Rerun Quick Test YES Remove breakout box. Replace processor. Reconnect processor and Throttle Position Sensor. Rerun Quick Test. |
