Mazda CX-5 Service & Repair Manual: Refrigerant Pressure Sensor Inspection [Full Auto Air Conditioner]
1. Install the manifold gauge.
2. Verify the high-pressure side reading of the manifold gauge.
3. Measure the terminal voltage at PCM terminal 2BB, 2AX and 2AJ
4. Using the graph below, measure and verify the terminal voltages at 2AX.
5. Follow the PCM inspection when measuring the other terminal voltages..
-
Terminal 2BB: Approx. 5 V (Ignition switch on)
-
Terminal 2AJ: 1.0 V or less
-
If the each voltage is not normal, inspect the related wiring harness.
-
If there is any malfunction, replace the related wiring harness.
-
If wiring harness is normal, replace the refrigerant pressure sensor.
Refrigerant Pressure Check
NOTE:
Measure the refrigerant pressure after approx.10 min have elapsed
from engine start.

Camshaft Position (CMP) Sensor
Purpose/Function
Detects the camshaft speed as basic information for mainly determining the
fuel injection timing and ignition timing.
Detects the camshaft speed and inputs it to the PCM as a CMP signal.
Construction
Intake CMP sensor
Installed on the cylinder head.

Turn and Lane-Change Signals
NOTE
• If an indicator light stays on without
flashing or if it flashes abnormally, one of the turn signal bulbs may be burned
out.
• A personalized function is available to change
the turn indicator sound volume.

Evaporator
Purpose
The evaporator cools the passing air.
Function
The evaporator vaporizes the atomized refrigerant flowing internally, and
the air passing through the evaporator is cooled by the release of latent heat.
The moisture in the air is condensed at this time and dehumidifie ...
