DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait atle-
ast 10 seconds before conducting the next test.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON and wait at least 5 seconds.

2.

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000006044842

1.

CHECK MAP SENSOR POWER SUPPLY CIRCUIT

1.

Disconnect manifold absolute pressure sensor (MAP) sensor harness connector.

2.

CHECK MAP SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between MAP sensor harness connector and ECM harness connector.

DTC No.

YES

>> GO TO 3.

NO

>> Repair open circuit, short to ground or short to power in harness or connectors.

3.

CHECK MAP SENSOR INTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Check the continuity between MAP sensor harness connector and ECM harness connector.

2.

Also check harness for short to ground and power.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair open circuit, short to ground or short to power in harness or connectors.

4.

CHECK MAP SENSOR

Check map sensor. Refer to

XX-XX, "*****"

.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace MAP sensor.

5.

CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to

XX-XX, "*****"

.

>> INSPECTION END

Component Inspection

INFOID:0000000006044845

1.

CHECK MAP SENSOR-I

1.

Turn ignition switch OFF.

2.

Start engine and warm it up to normal operating temperature.

3.

Turn ignition switch OFF, wait at least 5 seconds and then turn ON.

4.

Check the voltage between ECM harness connector terminals as follows.

NOTE:
• To avoid the influence of intake manifold vacuum, check the voltage 1 or more minutes past after engine

is stopped.

• Because the sensor is absolute pressure sensor, output value may differ depending on atmospheric

pressure and altitude.

5.

Measure the atmospheric pressure.

As the atmospheric pressure described on the synoptic chart is the value at sea level, compensate the
pressure with the following chart.

6.

Check the manifold absolute pressure sensor value corresponding to the atmospheric pressure.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace MAP sensor.

2.

CHECK MAP SENSOR-II

1.

Start engine and let it idle.

2.

Check intake manifold vacuum.

3.

Check the voltage between ECM harness connector terminals as per the following.

4.

Confirm the difference of the voltage when engine is stopped and at idling is within the values shown in
the following chart.

Is the inspection result normal?

YES

>> INSPECTION END

NO
