- B74 Manifold Absolute Pressure Sensor
- If a condition exists
Repair or replace as necessary
- Go to next step : If no condition exists
- Verify the scan tool parameter :
- BARO Sensor = Altitude Versus Barometric Pressure - The value should be within the range listed in the table.
- MAP Sensor = Altitude Versus Barometric Pressure - The value should be within the range listed in the table.
- If not in the specified range
- {BARO Sensor} Refer to : DTC P2227-P2230 .
