Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.
  1. Ignition - On/Vehicle - In Service Mode
  2. DTC P0097, P0098, P0099, P00EA, P00EB, P00EC, P14B6, U060F, U1346, U2011 = Not set
    • Go to next step: If none of the DTCs are set 
  3. Verify the following scan tool Freeze Frame/Failure Records parameters are within 25°C (45°F) of each other:
    • Start-Up IAT Sensor 1
    • Start-Up IAT Sensor 2
    • Start-Up IAT Sensor 3
    • If not within 25°C (45°F) of each other 
    1. Ignition/Vehicle - Off
      2. NOTE:

      Test the sensor that is colder or warmer than the other temperature sensor(s).

    2. Disconnect the appropriate electrical connector:
      • {IAT Sensor 1} B75C Multifunction Intake Air Sensor
      • {IAT Sensor 2} B75C Multifunction Intake Air Sensor
      • {IAT Sensor 3} B111B Turbocharger Boost/Intake Air Temperature Sensor
    3. Disconnect the appropriate electrical connector: K20 Engine Control Module
    4. Test for less than 2 ohms between the test points:
      • {B111B Turbocharger Boost/Intake Air Temperature Sensor} Low Reference circuit terminal 1@Component harness & The other end of the circuit@Control module harness
      • {B75C Multifunction Intake Air Sensor} Low Reference circuit terminal 3@Component harness & The other end of the circuit@Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • Go to next step: If less than 2 ohms
    5. Test for less than 2 ohms between the test points:
      • {B75C Multifunction Intake Air Sensor - IAT Sensor 1} Signal circuit terminal 1@Component harness & The other end of the circuit@Control module harness
      • {B75C Multifunction Intake Air Sensor - IAT Sensor 2} Signal circuit terminal 8@Component harness & The other end of the circuit@Control module harness
      • {B111B Turbocharger Boost/Intake Air Temperature Sensor - IAT Sensor 3} Signal circuit terminal 2@Component harness & The other end of the circuit@Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • Go to next step: If less than 2 ohms
    6. Test or replace the component: B75C Multifunction Intake Air SensororB111B Turbocharger Boost/Intake Air Temperature Sensor
    • Go to next step: If within 25°C (45°F) of each other 
  4. Verify the appropriate scan tool parameter:
    • IAT Sensor 1
    • IAT Sensor 2
    • IAT Sensor 3
    • Perform the action while monitoring the parameter:
    • Wiggle the harness and connector: B75C Multifunction Intake Air Sensor
    • Wiggle the harness and connector: B111B Turbocharger Boost/Intake Air Temperature 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 
  5. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

    Verify the DTC does not set.

    • If the DTC sets 

      Repeat the procedure starting at step 2

    • Go to next step: If the DTC is not set 
  6. All OK.
