- On the scan tool a good TP sensor 1 will typically display a TP angle of 8-10 percent at idle, and 76-77 percent at wide open throttle (WOT).
- An intermittent malfunction may be caused by fault in the TAC module electrical circuit. Inspect the wiring harness and components for an intermittent condition. Refer to Intermittent Conditions .
- Repair any electrical circuit faults that were found. Refer to Wiring Repairs .
- The information included in the Freeze Frame data can be useful in determining the vehicle operating conditions when the DTC first set.
