Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.
  1. If you were sent here from DTC P0068, P0121, P012B, or P1101 refer to Circuit/System Testing - step 1.
  2. Ignition ON.
  3. Verify the scan tool TB Idle Airflow Compensation parameter is less than 90%.
    • If less than 90% 
  4. Verify the scan tool TP Sensors 1 and 2 Agree/Disagree parameter displays Agree while performing the Throttle Sweep Test with a scan tool.
    • If Agree 
  5. Determine the current vehicle testing altitude.
  6. Verify the scan tool MAP Sensor pressure parameter is within the range specified in the Altitude Versus Barometric Pressure table.
    • The MAP Sensor pressure is not in range 

      Refer to Circuit/System Testing - step 1.

    • The MAP Sensor pressure is within range 
  7. Engine idling.
  8. Verify the scan tool MAP Sensor pressure parameter is between 26-52 kPa (3.8-7.5 psi) and changes with accelerator pedal input.
    • If not between 26-52 kPa (3.8-7.5 psi) or does not change 

      Refer to Circuit/System Testing - step 1

    • If between 26-52 kPa (3.8-7.5 psi) and changes 
  9. Verify the scan tool SC Inlet Pressure Sensor pressure parameter is within range specified in the Altitude Versus Barometric Pressure table.
    • The SC Inlet Pressure Sensor pressure is not in range 

      Refer to DTC P012B  for further diagnosis.

    • The SC Inlet Pressure Sensor pressure is within range 
  10. Verify the SC Inlet Pressure Sensor pressure parameter decreases after starting the engine.
    • The SC Inlet Pressure Sensor pressure did not decrease 

      Refer to DTC P012B  for further diagnosis.

    • The SC Inlet Pressure Sensor pressure decrease 
  11. Verify the scan tool MAF Sensor g/s parameter changes smoothly and gradually as the engine speed is increased and decreased while performing the actions listed below.
    1. Engine idling
    2. Perform the scan tool snapshot function.
    3. Increase the engine speed slowly to 3000 RPM and then back to idle.
    4. Exit from the scan tool snapshot and review the data.
    5. Observe the MAF Sensor parameter frame by frame with a scan tool.
    • The MAF Sensor parameter changes smoothly and gradually 
  12. 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.
  13. Verify a DTC does not set.
    • If the DTC sets 

      Refer to Circuit/System Testing - step 1.

    • If the DTC does not set 
  14. All OK.
