WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
The numbers below refer to the step numbers on the diagnostic procedures.
- 6
This step checks the integrity of the 5-volt reference and ground circuits of the TP sensors. - 7
This step determines if the 5-volt reference circuit or the sensor ground circuit is the cause of the DTC. - 8
If the scan tool displays 100 percent for the TP sensor 1 and the TP sensor 2 angle, this indicates that the TP sensor signal circuits are not the cause of the DTC. - 9
This step checks for excessive resistance in the TP sensor 5-volt reference circuit between the TP sensor harness connector and the PCM harness connector. - 10
This step checks for excessive resistance in the TP sensor ground circuit between the TP sensor harness connector and the PCM harness connector. - 11
This step checks for the TP sensor signal circuits for being shorted to another circuit in the PCM wiring harness between the PCM and the TP sensor wiring harness. - 16
When the PCM detects a problem within the throttle control system, more than one related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing one individual problem may correct more than one DTC. Keep this in mind when reviewing captured DTC info.
