Thread: P0135 O2 sensor fault

Hi,
I have a P0135 fault for the O2 sensor.

P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank1, Sensor1)

Also the same for the Bank 2.

I have replaced both sensors and still have the same fault.

MAF sensor appears to be working ok. In terms of air consumption.

I would appreciate any ideas or where to look.

I am told, by looking on the net, that it could be a short or open circuit.

Am I barking up the wrong tree?
How can you check the sensors out with a meter?

Cheers,

Chilly

If you wanted the official LR word on this code you could try:

TOPIx - TOPIx

You need a subscription to the site to access the information. You can buy a one hour model, year specific subscription to just the diagnostic information for £3.00.

The information should include a comprehensive diagnostic flow for the fault. This is basically what LR dealers would have access to.
