EXHAUST GAS PRESSURE SENSOR INSPECTION [MZR-CD 2.2]

id0140f2446000

Caution

•  Because the output characteristics of the exhaust gas pressure sensor are adjusted while it is installed to the bracket, replace the exhaust gas pressure sensor and the bracket as a single unit.

Note

•  Perform the following test only when directed.

Voltage Inspection

1.  While the connector is connected, remove the hoses attached to exhaust gas pressure sensor ports A and B.

2.  Switch the ignition to ON.

3.  Verify that the voltage at PCM terminal 1AD is within the specification.

•  If not as specified, replace the exhaust gas pressure sensor and the bracket as a single unit. (See EXHAUST GAS PRESSURE SENSOR/EXHAUST GAS PRESSURE CORRECTION TEMPERATURE SENSOR REMOVAL/INSTALLATION [MZR-CD 2.2].)

4.  Verify that the voltage variance at PCM terminal 1AD is within the specification when a pressure of 0—100 kPa is applied to exhaust gas pressure sensor port A.

•  If not as specified, replace the exhaust gas pressure sensor and the bracket as a single unit. (See EXHAUST GAS PRESSURE SENSOR/EXHAUST GAS PRESSURE CORRECTION TEMPERATURE SENSOR REMOVAL/INSTALLATION [MZR-CD 2.2].)
