- If any of the DTCs are set
- Go to next step: If none of the DTCs are set
- Verify the following parameters are within 25°C (45°F) of each other:
- Start-Up IAT Sensor 1
- Start-Up IAT Sensor 2
- If not in the specified range
- {Start-Up IAT Sensor 1} Refer to: DTC P0112-P0114
- {Start-Up IAT Sensor 2} Refer to: DTC P0097-P0099 or P00F4-P00F6
- Go to next step: If in the specified range
- Engine - Idling
- Verify the scan tool parameter: = -39 to 149°C (-38 to 300°F) and changes
- IAT Sensor 1
- IAT Sensor 2
- {LT4, LT5} IAT Sensor 3
- If not in the specified range or does not change
- {IAT Sensor 1} Refer to: DTC P0112-P0114
- {IAT Sensor 2} Refer to: DTC P0097-P0099 or P00F4-P00F6
- Go to next step: If in the specified range and changes
- Verify the appropriate scan tool parameter:
- IAT Sensor 1
- IAT Sensor 2
Perform the action while monitoring the parameter:
- Wiggle the harness and connector: B75C Multifunction Intake Air Sensor
- Wiggle the harness and connector: K20 Engine Control Module
- If the value spikes or drops out
Repair as necessary - Wiring/Terminal(s)/Electrical Connector(s)
- Go to next step: If the value does not spike or drop out
- All OK.
