Circuit Diagram
Description Heated Oxygen Sensor (HO2S) consists of zirconium and alumina and is installed on upstream and downstream of the Manifold Catalyst Converter (MCC).
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.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the intake actuator connector. 3. Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the intake actuator operates to the recirculation position when connected in reverse.
