WARNING Over-inflation or under-inflation can reduce tire life, adversely affect vehicle handling, and lead to sudden tire failure that may cause loss of vehicle control resulting in an accident.
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.
Repair procedures Inspection 1. Turn the ignition switch ON. 2. Manually operate the control switch and measure the voltage of the blower motor. 3. Select the control switch to raise the voltage until high speed.
