Circuit Diagram
Description Heated Oxygen Sensor (HO2S) consists of the zirconium and the alumina and is installed on upstream and downstream of the Warm-up Catalytic Converter (WCC).
Inspection 1. Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals. 2. Inspect the voltage value whether it is sufficient to be regular value or not. Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA] 3.
Inspection 1. Ignition "ON" 2. Manually operate the control switch and measure the voltage of blower motor. 3. Select the control switch to raise voltage until high speed. Specification FanMotor VoltageManualFirst speed3.8 ±0.5VSecond speed5.
