Circuit/System Verification

  1. Verify that DTC P0641 or P0651 is not set.
  2. Verify that restrictions do not exist in the exhaust system. Refer to Restricted Exhaust .
  3. Engine operating at idle, observe the scan tool MAF Sensor parameter. The reading should be between 1,700-3,200 Hz depending on the ECT.
  4. A wide open throttle (WOT) acceleration from a stop should cause the MAF Sensor parameter on the scan tool to increase rapidly. This increase should be from 2-6 g/s at idle to greater than 150 g/s at the time of the 1-2 shift.
  5. Use the scan tool and compare the MAF Sensor parameter to a known good vehicle, under various operating conditions.
  6. Verify the proper operation of the MAP sensor. A skewed MAP sensor will cause the BARO value to be inaccurate. Refer to DTC P0106 .
  7. 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.
