Circuit/System Verification
WARNING: This page is about a different variant/trim than selected.
- Ignition - On / Vehicle - In Service Mode
- Verify DTC P00E9, P00EA, P00EB, P00EC, P007C, P007D, P007E, P10D6, P10D7, P10D8, P0181, P2610 is not set.
- If any of the DTCs are set
- Go to next step: If none of the DTCs are set
- Verify the following parameters are within 20°C (36°F) of each other:
- Start-Up Charge Air Cooler Temperature
- Start-Up Charge Air Cooler Temperature Sensor 2
- Start-Up Intake Air Temperature Sensor 3
- If not in the specified range
- Refer to: DTC P007C-P007E or P10D6-P10D8
- Go to next step: If in the specified range
- Engine - Idling
- Verify the scan tool parameter: = -39 to 215°C (-38 to 419°F) and changes
- Charge Air Cooler Temperature Sensor
- Charge Air Cooler Temperature Sensor 2
- If not in the specified range or does not change
- Refer to: DTC P007C-P007E or P10D6-P10D8
- Go to next step: If in the specified range and changes
- Perform the action while monitoring the parameter:
- Charge Air Cooler Temperature Sensor
- Charge Air Cooler Temperature Sensor 2
- Wiggle the harness and connector: B193A Charge Air Cooler Inlet Temperature Sensor - The value should not spike or drop out.
- Wiggle the harness and connector: B193B Charge Air Cooler Outlet Temperature Sensor - The value should not spike or drop out.
- Wiggle the harness and connector: K20 Engine Control Module - The value should not spike or drop out.
- 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
- Ignition/Vehicle & All vehicle systems - Off
- Verify the following conditions do not exist:
- B65 Intake Manifold Pressure and Air Temperature Sensor - Leaking @ O-Ring - Missing / Visible Damage
- Intake Air Duct - Collapsed/Loose Clamps/Restricted/Visible Damage
- Intake Manifold - Cracked/Loose Clamps/Visible Damage - Refer to: Intake Manifold Replacement
- Charge Air Cooler
- Leaking - Loose Clamps/Visible Damage
- Restricted - Moisture/Ice
Refer to: Charge Air Cooler Diagnosis
- If a condition exists - Repair or replace as necessary
- All OK.
NOTE:
To minimize the effects of residual engine heat and heating elements inside the sensor, perform step 3 of this procedure only if the ignition has been Off for longer than 8 h.
