When I had the work done they didn't reset the CEL ( they would have charged me). So today I unplugged the battery and when I started the car the CEL immediately came back on.

The code is P0134, no activity from the front sensor on the passenger side.

How can this be, my sensor is newish. What could possibly be wrong?

Any help would be appreciated,
marc
