- If none of the DTCs are set
- Determine the current vehicle testing altitude.
- Verify the scan tool parameter:
- MAP Sensor = Altitude Versus Barometric Pressure - The value should be within the range listed in the table.
- Boost Pressure = Altitude Versus Barometric Pressure - The value should be within the range listed in the table.
- BARO = Altitude Versus Barometric Pressure - The value should be within the range listed in the table.
- If not in the specified range
- {MAP Sensor}Refer to:DTC P0106 .
- {Boost Pressure}Refer to:DTC P0236 .
- {BARO}Refer to: Circuit/System Testing.
- Go to next step: If in the specified range
- Verify the scan tool parameter:BARO = The value should not spike or drop out.
Perform the action while monitoring the parameter:
- Wiggle the harness and connector:B75C Multifunction Intake Air Sensor
- Wiggle the harness and connector:X3 @K20 Engine Control Module
- If the value spikes or drops out
Repair as necessary - Wiring / Terminal(s) / Electrical Connector(s)
