Circuit/System Verification
- Ignition ON, observe the DTC information with a scan tool. Verify DTCs P0641 or P0651 are not set.
- If either DTC is set, refer to DTC P0641 or P0651 .
- Start the engine, observe the rough road sensor voltage parameter. The reading should be between 1.1-3.7 volts.
- If the vehicle passes the Circuit/System Verification test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.
