2000 Lexus LS 400 V8 Two Wheel Drive Automatic
Need help with O2 sensor readings.
I have LS400 2000 model which has 4 Oxygen Sensors.
I think that I may have some problem in my O2 sensors.
if you guys could check this readings and help me with this issue & tell me if these sensors are either functioning correctly or not.
These are readings of O2 sensor back finally on idle without acceleration.
I do not have any DTC
the only problem is that
fuel mileage is low which is 19 - 20 MPG on highway compared with other LS400 owners who get 24-30 MPG on highway.
I have changed spark plugs, cleaned engine air filter. But I think it may be because of these O2 sensors.
Bank 1 sensor 2 readings are not similar to Bank 2 sensor 2 readings, does this means that I had to replace the sensor.
I don't know about these readings, could you tell me in case if any of these readings are wrong.
