Circuit/System Verification
WARNING: This page is about a different variant/trim than selected.
- Ignition ON, verify that DTC P0641, P0651, P0697, or P06A3 is not set.
- If any of the DTCs are set
Refer to DTC P0641, P0651, P0697, or P06A3 (ECM) for further diagnosis.
- If none of the DTCs are set
- If any 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.
- If the MAP Sensor parameter is in range
- If the MAP Sensor parameter is not in range
- Verify the engine is equipped with a turbocharger.
- If not equipped with a turbocharger
Refer to Step 6.
- If equipped with a turbocharger
- If not 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.
- If between 0.3-4.8 V and changes
Refer to Step 7.
- If not between 0.3-4.8 V or does not change
- 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.
- If between 0.2-4.5 V and changes
- If not between 0.2-4.5 V or does not change
- Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. 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 the DTC sets
Refer to Circuit/System Testing.
- If the DTC does not set
- If the DTC sets
