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.

Air Fuel Ratio (A/F) Sensor Heater Control
Outline
Based on the control of the A/F sensor heater, a stabilized oxygen concentration
is detected even at low exhaust temperatures, and feedback control of fuel injection
even at cold engine start is made possible for improved cold temperature exhaust
emission performance.
