Those things are easy to break. As for 37000 miles, it all depends. Yes,
it is easy to connect them wrong. However, like most hardware devices,
they fail whenever they fail. Mine was replaced long before that mileage.

In any case, O2 sensers are covered under warranty.

Code reader showed P0155. Code in my Bentley manual: "Heater Circuit, Bank 2, Sensor 1" Autozone tech said check connectors, I shouldn't be having a problem with the O2 sensors at 37,000 miles.

It is a problem somewhere with the emissions controls. As the car is still under warranty, take it to the dealer. A common problem is one of the O2 sensors, but the code reader will tell them which one and what is wrong with it. Jim > Joe

With 37,500 miles! Any chance that its something simple? I just passed emissions test a few weeks ago. I checked the gas cap, but that was fine. I do oil changes myself so I don't reset the oil change indicator.(Low mileage) That can't be it? Joe
