Thanks for the responses. I am not sure what the difference is between a CEL and a “Service Engine Soon” light, but the light actually says “Service Engine Soon.”
The Actual code is P0155. The readouts did not give any information on sensor # or bank #.
There are about 70,000 miles on the car. I am the second owner and it has been properly maintained as far as I know.
I have a good mechanic that I trust, I just don’t have the $ right now to take it to him. I am trying to figure out whether I can keep driving for a while or whether I need to take it in ASAP. I’d rather not do more damage, but I am feeling the $ pinch.
Thanks very much for your thoughts!
