Though I am not sure this is the oxygen sensor again yet... I am wondering what possible problems (if it's only a few..) could cause an oxygen sensor to go bringing on the check engine light. I just had the sensor replaced not long ago and already the check engine light is on again.... might be the same problem... might not be... I will find out on monday. If anyone can help me out it would be appriciated.

 

Pull the DTC codes, don't erase the CEL and let us know what you've got---then we might be able to help. At this point it would all be guessing.

 

Yep. No need for that. Pull the code 2006 you should be able to do the odometer trick to pull up the code. Check your owners manual or do a Search for that as thre have been plenty of them floating around.
