Code No. P0105: Barometric Pressure Sensor System

FUNCTION

The barometric pressure sensor converts the barometric pressure into a voltage signal and inputs the signal to the engine-A/T-ECU.
In response to the signal, the engine-A/T-ECU corrects the fuel injection amount, etc.

TROUBLE JUDGMENT

Check Conditions

2 seconds later after the ignition switch has been in ON position or the engine has started up.
The battery voltage is 8 V or more.

Judgment Criteria

The sensor output voltage is 4.5 V or more (barometric pressure of above 114 kPa or equivalent) for 4 seconds.

or

The sensor output voltage is 0.2 V or less (barometric pressure of below 53 kPa or equivalent) for 4 seconds.

PROBABLE CAUSE

Failed barometric pressure sensor

DIAGNOSIS PROCEDURE

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

Q. Is the diagnosis code set?

	Replace engine-A/T-ECU.

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