Component Function Check

1.CHECK REFRIGERANT PRESSURE SENSOR OVERALL FUNCTION

  1. Start engine and warm it up to normal operating temperature.
  2. Turn A/C switch and blower fan switch ON.
  3. Check the voltage between ECM harness connector terminals.

Is the inspection result normal?


Is the inspection result normal? YES >> INSPECTION END

NO >> Proceed to EC-465, "Diagnosis Procedure".

Diagnosis Procedure

1.CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY

  1. Turn ignition OFF.
  2. Disconnect refrigerant pressure sensor harness connector.
  3. Turn ignition switch ON.
  4. Check the voltage between refrigerant pressure sensor harness connector and ground.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 3.

NO >> GO TO 2.

2.CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY CIRCUIT

  1. Turn ignition switch OFF.
  2. Disconnect ECM harness connector.
  3. Check the continuity between refrigerant pressure sensor harness connector and ECM harness connector.


  1. Also check harness for short to ground.

Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.

NO >> Repair or replace error-detected parts.

3.CHECK REFRIGERANT PRESSURE SENSOR GROUND

  1. Turn ignition switch OFF.
  2. Disconnect ECM harness connector.
  3. Check the continuity between refrigerant pressure sensor harness connector and ECM harness connector.


  1. Also check harness for short to power.

Is the inspection result normal? YES >> GO TO 4.

NO >> Repair or replace error-detected parts.

4.CHECK REFRIGERANT PRESSURE SENSOR INPUT SIGNAL CIRCUIT

  1. Check the continuity between ECM harness connector and refrigerant pressure sensor harness connector.


  1. Also check harness for short to ground and to power.

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace error-detected parts.

5.CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to GI-39, "Intermittent Incident".

Is the inspection result normal? YES >> Replace refrigerant pressure sensor. Refer to HAC-110, "Removal and Installation" (For automatic air condittioner), or HAC-191, "Removal and Installation" (For manual air condittioner).

NO >> Repair or replace error-detected parts.
