MONITOR DESCRIPTION


  1. Active Air fuel Ratio Control

    The ECM usually performs air fuel ratio feedback control so that the air fuel ratio sensor output indicates a near stoichiometric air fuel level. This vehicle includes active air fuel ratio control in addition to regular air fuel ratio control. The ECM performs active air fuel ratio control to detect any deterioration in the Three-Way Catalytic Converter (TWC) and heated oxygen sensor malfunctions (refer to the diagram below).

    Active air fuel ratio control is performed for approximately 30 seconds while driving with a warm engine. During active air fuel ratio control, the air fuel ratio is forcibly regulated to become lean or rich by the ECM. If the ECM detects a malfunction, a DTC is stored.

  2. Abnormal Voltage Output of Heated Oxygen Sensor (DTCs P013613 and P015613)

    While the ECM is performing active air fuel ratio control, the air fuel ratio is forcibly regulated to become rich or lean. If the sensor is not functioning properly, the voltage output variation is small. For example, when the heated oxygen sensor voltage does not increase to 0.71 V or higher during active air fuel ratio control, the ECM determines that the sensor voltage output is abnormal and stores DTC P013613 or P015613.

    B0075SOE01

  3. Open in Heated Oxygen Sensor Circuit (DTCs P013617 and P015617)

    During active air fuel ratio control, the ECM calculates the Oxygen Storage Capacity (OSC)* of the Three-Way Catalytic Converter (TWC) by forcibly regulating the air fuel ratio to become rich or lean.

    If the heated oxygen sensor has an open circuit, or the voltage output of the sensor noticeably decreases, the OSC indicates an extraordinarily high value. Even if the ECM attempts to continue regulating the air fuel ratio to become rich or lean, the heated oxygen sensor output does not change.

    While performing active air fuel ratio control, when the target air fuel ratio is rich and the heated oxygen sensor voltage output is less than 0.21 V (lean), the ECM interprets this as an abnormally low sensor output voltage and stores DTC P013617 or P015617.

    Tech Tips

    *: The TWC has the capability to store oxygen. The OSC and the emission purification capacity of the TWC are mutually related. The ECM determines whether the catalyst has deteriorated based on the calculated OSC value.

  4. High or Low Impedance of Heated Oxygen Sensor (DTCs P013611 and P015611 or P013614 and P015614)

    B0072WHE03

    During normal air fuel ratio feedback control, there are small variations in the exhaust gas oxygen concentration. In order to continuously monitor the slight variation of the heated oxygen sensor signal while the engine is running, the impedance* of the sensor is measured by the ECM. The ECM determines that there is a malfunction in the sensor when the measured impedance deviates from the standard range.

    *: The effective resistance in an alternating current electrical circuit.

    Tech Tips


    • The impedance cannot be measured using an ohmmeter.

    • DTC P013611 or P015611 indicates the deterioration of the heated oxygen sensor. The ECM stores the DTC by calculating the impedance of the sensor when the typical enabling conditions are satisfied (2 driving cycles).

    • DTC P013614 or P015614 indicates an open or short circuit in the heated oxygen sensor (2 driving cycles). The ECM stores the DTC when the impedance of the sensor exceeds the threshold 15 kΩ.

  5. Extremely High Output Voltage of Heated Oxygen Sensor (DTCs P013615 and P015615)

    The ECM continuously monitors the heated oxygen sensor output voltage while the engine is running.

    DTC P013615 or P015615 is stored if the heated oxygen sensor voltage output is 1.2 V or higher for 10 seconds or more.

  6. Abnormal Voltage Output of Heated Oxygen Sensor During Fuel-cut (DTCs P013623 and P015623)

    The sensor output voltage drops to less than 0.2 V (extremely lean status) immediately when the vehicle decelerates and fuel cut is operating. If the voltage does not drop to less than 0.2 V for 1073.725 seconds or more, the ECM determines that the sensor response has deteriorated, illuminates the MIL and stores a DTC.

  7. Abnormal Voltage Output of Heated Oxygen Sensor During Fuel-cut from Rich Condition (DTCs P013A00 and P013C00)

    If the sensor output voltage does not drop from 0.35 to 0.2 V immediately when the vehicle decelerates and fuel cut is operating, the ECM illuminates the MIL and stores a DTC.

      Remains at less than 3.3 V

      Tech Tips

      A normal heated oxygen sensor voltage (O2 Sensor Voltage B1S2 or O2 Sensor Voltage B2S2) reacts in accordance with increases and decreases in fuel injection volumes. When the air fuel ratio sensor voltage (A/F (O2) Sensor Voltage B1S1 or A/F (O2) Sensor Voltage B2S1) remains at either less or higher than 3.3 V despite the heated oxygen sensor indicating a normal reaction, the air fuel ratio sensor is malfunctioning.
