- Determine the current vehicle testing altitude.
- Verify the scan tool parameter : MAP Sensor = The value should be within the range listed in the table : Altitude Versus Barometric Pressure
- If not in the specified range
Refer to : DTC P0106, P0107, or P0108
- Go to next step : If in the specified range
- If not in the specified range
- Verify the scan tool parameter : BARO Sensor 1 = The value should be within the range listed in the table : Altitude Versus Barometric Pressure
- If not in the specified range
Refer to : DTC P2227-P2230
- Go to next step : If in the specified range
- If not in the specified range
- Verify the scan tool parameter : BARO Sensor 2 = The value should be within the range listed in the table : Altitude Versus Barometric Pressure
- If not in the specified range
Refer to : Circuit/System Testing
- Go to next step : If in the specified range
- If not in the specified range
- Verify the scan tool parameter : BARO Sensor 2 = The value should not spike or drop out.
