Code No. P2229: Barometric Pressure Sensor Circuit High 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 JUDGMENT

Check Conditions

More than 2 seconds have passed since the engine starting sequence was completed.
Battery positive voltage is more than 8 V.

Judgement Criterion

Barometric pressure sensor output signal is more than 113 kPa (approximately 1,200 m below sea level) for 10 seconds.

PROBABLE CAUSE

Failed barometric pressure sensor

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis code

Reconfirmation of diagnosis code.

Q. Is the diagnosis code set?

	Replace the engine-ECU.

	Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
