SKYACTIV-G 2.5

1.  Install the manifold gauge. (See MANIFOLD GAUGE SET CONNECTION.)

2.  Verify the high-pressure side reading of the manifold gauge.

3.  Measure the terminal voltage at PCM terminal 2AZ, 2AV and 2AI.

4.  Using the graph below, measure and verify the terminal voltages at 2AV.

5.  Follow the PCM inspection when measuring the other terminal voltages. (See PCM INSPECTION [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].) (See PCM INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT CYLINDER DEACTIVATION)].)

•  Terminal 2AZ: Approx. 5 V (Ignition switch ON)

•  Terminal 2AI: 1.0 V or less

―  If each voltage is not normal, inspect the related wiring harness.

•  If there is any malfunction, replace the related wiring harness.

•  If the wiring harness is normal, replace the refrigerant pressure sensor.

SKYACTIV-G 2.5T

1.  Install the manifold gauge. (See MANIFOLD GAUGE SET CONNECTION.)

2.  Verify the high-pressure side reading of the manifold gauge.

3.  Measure the terminal voltage at PCM terminal 2Y, 2W and 2V.

4.  Using the graph below, measure and verify the terminal voltages at 2W.

5.  Follow the PCM inspection when measuring the other terminal voltages. (See PCM INSPECTION [SKYACTIV-G 2.5T].)

•  Terminal 2Y: Approx. 5 V (Ignition switch ON)

•  Terminal 2V: 1.0 V or less

―  If each voltage is not normal, inspect the related wiring harness.

•  If there is any malfunction, replace the related wiring harness.

•  If the wiring harness is normal, replace the refrigerant pressure sensor.

SKYACTIV-D 2.2

1.  Install the manifold gauge. (See MANIFOLD GAUGE SET CONNECTION.)

2.  Verify the high-pressure side reading of the manifold gauge.

3.  Measure the terminal voltage at PCM terminal 2BB, 2BH and 2BD.

4.  Using the graph below, measure and verify the terminal voltages at 2BH.

5.  Follow the PCM inspection when measuring the other terminal voltages. (See PCM INSPECTION [SKYACTIV-D 2.2].)

•  Terminal 2BB: Approx. 5 V (Ignition switch ON)

•  Terminal 2BD: 1.0 V or less

―  If each voltage is not normal, inspect the related wiring harness.

•  If there is any malfunction, replace the related wiring harness.

•  If the wiring harness is normal, replace the refrigerant pressure sensor.
