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.

Rear Shock Absorber Disposal
WARNING:
Whenever drilling into a rear shock absorber, wear protective eye wear. The
gas in the rear shock absorber is pressurized, and could spray metal chips into
the eyes and face when drilling.
1. Clamp a rear shock absorber on a flat surface or with the piston pointing
