Kia Sportage: Air conditioning System / A/C Pressure Transducer Description and operation
A/C pressure transducer converts the pressure value of high pressure line into
voltage value after measuring it. Based on the converted voltage value, engine
ECU controls cooling fan by operating it at high or low speed. Engine ECU stops
the operation of compressor when the temperature of refrigerant line is too
high or low irregularly to optimize air conditioning system.

Replacement

Since the sidewalls of radial tires are thinner, they can be damaged by mounting
some types of snow chains on them. Therefore, the use of snow tires is recommended
instead of snow chains. Do not mount tire chains on vehicles equipped with aluminum
wheels; snow chains may cause damage to the ...
Check the fluid level in the reservoir periodically. The fluid level should be
between MAX (Maximum) and MIN (Minimum) marks on the side of the reservoir.
Before removing the reservoir cap and adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent brake fluid contam ...
