Though I am not sure this is the oxygen sensor again yet... I am wondering what possible problems (if 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 tomorrow. If anyone can help me out it would be appriciated.

 

You might want to get a OBDll checker. There is a connector to the left of your steering column. I purchased one at Costco for $35.00. It will give you the P codes that are stored in your engine controller.

 

You are in a dead area and you need to post in your era of year of make.
