>> Proceed to 

ECM-185, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010702910

1.

CHECK BAROMETRIC PRESSURE SENSOR POWER SUPPLY-1

1.

Turn ignition switch OFF.

2.

Disconnect barometric pressure sensor harness connector.

3.

Turn ignition switch ON.

4.

Check the voltage between barometric pressure sensor harness connectors.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> GO TO 2.

2.

CHECK BAROMETRIC PRESSURE SENSOR POWER SUPPLY-2

Check the voltage between barometric pressure sensor harness connector and ground.

DTC No.

Component Inspection

INFOID:0000000010702911

1.

COMPONENT FUNCTION CHECK

1.

Turn ignition switch ON.

2.

Check the voltage between ECM harness connector terminals as follows.

NOTE:
Since this sensor is an absolute pressure sensor, values vary with ambient pressure and altitude.

3.

Measure the barometric pressure.
NOTE:
As the barometric pressure described on the synoptic chart is the value at sea level, compensate the
pressure with the following chart.
