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.

Engine Tune Up [Mzr 2.0, Mzr 2.5]
NOTE:
If the accelerator pedal is depressed continuously for a specified time,
the engine speed may decrease to the idle speed. This is due to the fuel cut
control operation, which prevents overheating, and it does not indicate a malfunction.
Engine Tune-up Preparation
1. Verify ...
Wheel Alignment Pre Inspection
1. Park the vehicle on a level ground, in an unloaded condition*, and with the
wheels straight forward.
*: Unloaded condition.....Fuel tank is full. Engine coolant and engine oil are
at specified level. Spare tire, jack and tools are in designated position.
2. Inspect the tire pressure.
