Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.

Ignition ON, verify that DTC P0641, P0651, P0697, P06A3, or P06D2 is not set.
- If any of the DTCs are set
  Refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.
- Go to next step: If none of the DTCs are set
Determine the current vehicle testing altitude.
Verify the scan tool MAP Sensor parameter is within the range specified in the Altitude Versus Barometric Pressure table.
- If the MAP Sensor parameter is not in range
  Refer to Circuit/System Testing for further diagnosis.
- Go to next step: If the MAP Sensor parameter is within range
Verify the engine is equipped with a turbocharger.
- If not equipped with a turbocharger
  Refer to Step 6.
- Go to next step: If equipped with a turbocharger
Engine idling, verify the scan tool MAP Sensor voltage parameter is between 0.3 - 4.8 V and changes with accelerator pedal input.
- If not between 0.3 - 4.8 V or does not change
  Refer to Circuit/System Testing.
- Go to next step: If between 0.3 - 4.8 V and changes
  Go to next step: Refer to Step 7.
Engine idling, verify the scan tool MAP Sensor voltage parameter is between 0.2 - 4.5 V and changes with accelerator pedal input.
- If not between 0.2 - 4.5 V or does not change
  Refer to Circuit/System Testing.
- Go to next step: If between 0.2 - 4.5 V and changes
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed in the Freeze Frame/Failure Records data.
Verify the DTC does not set.
- If any DTC sets
  Refer to Circuit/System Testing.
- Go to next step: If no DTC sets
