Default engine light came one
I have a 2002 Dodge Ram 1500 and the engine light came on today. I was able to get a code that is P0133. Could the idylling sensor cause this or is it another problem. It has been running fine in town but when putting it on the highway it revs itself up.

"O2 Sensor Circuit Slow response". I'd say clear it and see what happens.

Yep, normal procedure is to reset the PCM and see if the code comes back. If it does, change out the pre-cat O2 sensor...
