Nissan Sentra Service Manual: Refrigerant pressure sensor
Component Function Check
1.CHECK REFRIGERANT PRESSURE SENSOR OVERALL FUNCTION
- Start engine and warm it up to normal operating temperature.
- Turn A/C switch and blower fan switch ON.
- Check the voltage between ECM harness connector terminals.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-465, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY
- Turn ignition OFF.
- Disconnect refrigerant pressure sensor harness connector.
- Turn ignition switch ON.
- Check the voltage between refrigerant pressure sensor harness connector and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between refrigerant pressure sensor harness connector and ECM harness connector.
- 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
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between refrigerant pressure sensor harness connector and ECM harness connector.
- 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
- Check the continuity between ECM harness connector and refrigerant pressure sensor harness connector.
- 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.
