Circuit/System Verification
- Ignition ON, observe the diagnostic trouble code (DTC) information with a scan tool. Verify that DTC P0651 is not set.
- Compare the scan tool BARO pressure parameter to the Altitude Versus Barometric Pressure
table. The BARO should be within the specified range displayed in the table for the specific altitude.
- If not within the specified range, refer to DTC P0106
for further diagnosis.
- Compare the scan tool Air Pressure Sensor pressure parameter to the BARO reading. The readings should be within 3 kPa (0.5 psi).
- Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
