Circuit/System Verification

  1. Verify that DTCs P0641 and P0651 are not set.
    • If any of the DTCs are set, refer to DTC P0641  or P0651  .
  2. Verify that restrictions do not exist in the exhaust system. Refer to Restricted Exhaust .
  3. Verify that the engine is in good mechanical condition. Refer to Symptoms - Engine Mechanical for the 4.4L engine.
  4. Ignition ON, observe the scan tool MAP, SC Inlet Pressure, and BARO parameters. Verify the MAP, SC Inlet Pressure, and BARO sensor parameters are within 5 kPa of each other.
  5. Ignition ON, observe the MAP Sensor kPa parameter with a scan tool. Start the engine. The MAP Sensor kPa parameter should change.
  6. Engine running at idle, observe and record the MAP Sensor parameter kPa value with a scan tool. Slowly increase the engine speed from idle to 2,000 RPM, then allow the engine speed to return idle. The MAP sensor parameter should increment to a higher value at 2,000 RPM and return to the recorded idle value.
  7. Ignition ON, compare APP sensors 1 and 2 percentages with a scan tool. Verify that they do not differ more than 5 percent while performing a slow pedal sweep is performed.
  8. Ignition ON, observe the scan tool MAP sensor parameter. Start the engine. The MAP Sensor parameter should change.
  9. Engine running, observe the DTC information with a scan tool. DTCs P0106 should not set.
  10. 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.
