Ignition ON, observe the DTC information with a scan tool. Verify DTCs P0697 or P06A3 are not set. If a DTC is set, refer to DTC P0641, P0651, P0697, or P06A3 (ECM) for further diagnosis.2. Ignition ON, observe the scan tool Accelerator Pedal Position percentage parameter. The scan tool shoulddisplay 0 percent.3. Observe the scan tool APP Sensor 1 and 2 Agree/Disagree parameter while performing the followingtests: Rapidly depress the accelerator pedal from the rest position to the wide open throttle position(WOT) and release pedal. Repeat the procedure several times. Slowly depress the accelerator pedal to WOT and then slowly return the pedal to closed throttle.Repeat the procedure several times.The APP Sensor 1 and 2 Agree/Disagree parameter should display Agree.4. Observe the DTC information with a scan tool. DTCs P2122, P2123, P2127, P2128, or P2138 should notset.5. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. Youmay also operate the vehicle within the conditions that you observed from the Freeze Frame/FailureRecords data.</blockquote>
