Oxygen Sensor Signal Voltage Inspection
1. Measure the oxygen sensor signal voltage between the ECU
terminal No.11 and No.9. Maintain the engine speed ia at
idle while the coolant temperature is over 80°C.
Specified Value
If the measured value is not within the specified value, the
possible cause may be in cable, oxygen sensor or ECU.
Oxygen Sensor Heating Voltage Inspection
1. Measure the oxygen sensor heating voltage between the
ECU terminal No.11 and No.9. Maintain the engine speed ia
at idle while the coolant temperature is over 80°C.
Specified Value
If the measured value is not within the specified value, the
possible cause may be in cable, oxygen sensor or ECU.
Oxygen Sensor Heating Current Consumption
Inspection
1. Measure the oxygen sensor heating current consumption
between the ECU terminal No.9 and No.5 while the ignition
switch is in "ON" position.
Specified Value
