Description and operation Description The A/C Pressure Transducer (APT) converts the pressure value of high pressure line into voltage value after measuring it. By converted voltage value, engine ECU controls the cooling fan by operating it high speed or low speed.
Troubleshooting 1) After replacing H/UNIT, always check that the system operates properly. 2) If the failure persists after replacing the H/UNIT, do not replace the unit.
