- Go to next step: If none of the DTCs are set
- If any of the DTCs are set
- Verify the scan tool parameter: Manifold Absolute Pressure Sensor = The value should be within the range listed in the table: Altitude Versus Barometric Pressure
- If not in the specified range
Refer to: Circuit/System Testing
- Go to next step: If in the specified range
- If not in the specified range
- Engine - Idling - At normal operating temperature.
- Accessories - Off
- Verify the scan tool parameter:
- Manifold Absolute Pressure Sensor = The value should be within the range listed in the table: Altitude Versus Barometric Pressure
- Manifold Absolute Pressure Sensor = The value should change with accelerator pedal input.
- If not in the specified range or does not change
Refer to: Circuit/System Testing
- Go to next step: If in the specified range and changes
- Verify the scan tool parameter: Manifold Absolute Pressure Sensor = The value should not spike or drop out.
Perform the action while monitoring the parameter:
- Wiggle the harness and connector: B65 Intake Manifold Pressure and Air Temperature Sensor
- Wiggle the harness and connector: K20 Engine Control Module
- If the value spikes or drops out
Repair as necessary - Wiring/Terminal(s)/Electrical Connector(s)
