Description
This dtc is output when the refrigerant pressure is either extremely low (0.19 Mpa [2.0 Kgf/cm2, 28 psi] or less) or extremely high (3.14 Mpa [32.0 Kgf/cm2, 455 psi] or more). The air conditioning pressure sensor, which is installed on the pipe of the high pressure side, detects the refrigerant pressure and sends refrigerant pressure signals to the air conditioning amplifier. The air conditioning amplifier determines the pressure from the signals in accordance with the sensor characteristics, and controls the compressor accordingly.

Steering angle sensor zero point malfunction
Description
The skid control ecu learns the steering sensor zero point every time the
ignition switch is turned on and
the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds.
The ecu also stores the
previous zero point.
If front wheel alignment or the steering wh ...
