HEATED OXYGEN SENSOR OUTPUT VOLTAGE | REMARKS |
0.6 - 1.0 V | High load operation makes air/fuel ratio richer and normal heated oxygen sensor (rear) also can output voltage of 0.6 - 1.0 V. |
note | If the temperature of sensing area does not reach the high temperature [of approximately 400°C (752°F) or more] even though the heated oxygen sensor (rear) is normal, the output voltage would be possibly low in spite of the rich air-fuel ratio. |
note | When the vehicle is driven with high loads, the temperature of the sensing area of the heated oxygen sensor (rear) is sufficiently high. Thus, it is not necessary to apply the voltage to the heater. |
