e-SKYACTIV (Refrigerant pressure sensor No.1)

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 T, S and Y.

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

5.  Follow the PCM inspection when measuring the other terminal voltages. (See PCM INSPECTION.)

•  Terminal Y: Approx. 5 V (Main power ON (READY off or on))

•  Terminal T: 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.
