Problems With My Verso

[GMalcolm30]

Hi, ive been having some problems with my Corolla Verso.

The car was in the garage and the fault code P0037 came up, they then replaced the upstream sensor.

After we left the garage and drove a few miles the engine warning light came on and the car went back to the garage.

They again tested the fault codes and the same P0037 code came up, they are now saying the downstream sensor needs replaced, does this sound like a usual issue or have the garage made a mistake and are trying to make us pay for it? thanks

Have you tried searching Google for info on this fault? Try these. Neither mention an Upstream or Downstream sensor... <shrug>
