Circuit/System Verification
- Service Mode active, verify DTC P0697 is not set.
- Determine the current vehicle testing altitude. Service Mode active, observe the scan tool BARO Sensor parameter. Compare the parameter to the Altitude Versus Barometric Pressure
table. The BARO sensor pressure parameter should be within the specified range indicated in the table.
- Service Mode active, observe the scan tool MAP sensor parameter. Ignition ON, engine running, the MAP Sensor parameter should change.
- 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.
