Code No. P2228: Barometric Pressure Sensor Circuit Low Input
FUNCTION
- The barometric pressure sensor converts the barometric pressure into a voltage signal and inputs the signal to the engine-ECU.
- In response to the signal, the engine-ECU corrects the fuel injection amount, etc.
TROUBLE JUDGEMENT
Check Conditions
- More than 2 seconds have passed since the engine starting sequence was completed.
- Battery positive voltage is more than 6 V.
Judgement Criterion
- Barometric pressure sensor output signal is less than 49 kPa for 10 seconds.
FAIL-SAFE AND BACKUP FUNCTION
- Control as if the barometric pressure is 101 kPa.
PROBABLE CAUSE
- Failed barometric pressure sensor
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE diagnosis code
Replace the engine-ECU (integrated with barometric pressure sensor).
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions 
).
