Signal Waveform
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the OCV connector. 3. Measure resistance between the OCV terminals 1 and 2. 4.
Replacement 1. Remove the condenser. 2. Remove the cap (B) on the bottom of the condenser with the L wrench (A). Tightening torque : 9.81 ~ 14.71 N.m (1.0 ~ 1.5 kgf.m, 7.2 ~ 10.8 lb-ft) 3. Remove the receiver-drier (A) from condenser using a long nose plier.
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 at high speed or low speed.
