Mazda 3 Service Manual: Refrigerant Pressure Sensor Inspection [Manual Air Conditioner]
MZR 2.0, MZR 2.5
1. Install the manifold gauge.
2. Verify the high-pressure side reading of the manifold gauge.
3. Measure the terminal voltage of the climate control unit.
-
1G,1H and 2J
4. Verify that below graph as measure the terminal voltage 2J.
5. Follow the climate control unit inspection when measure the other terminal voltage..
-
Terminal 1G: 1.0 V or less
-
Terminal 1H: Approx. 5 V (Ignition switch on)
-
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.

System
The system operates only when the driver
is in the vehicle or within operational
range while the key is being carried.
NOTE
When the battery power is low, or in
places where there are high-intensity radio
waves or noise, the operational range
may become narrower or the system may
not operate ...
Tire Pressure Adjustment (With TPMS)
1. Use of a digital gauge is recommended for accurate measurement of the air
pressure.
2. Tire pressure lowers gradually as time passes. Due to this, monthly air pressure
inspection is recommended.
3. Perform tire pressure adjustment before driving. (When tires are cold.)
