I have a right rear o2 sensor that is malfunctioning. Apparently the heating element is not working. I was advised that the sensor still works, but not until it heats up on it's own. I am still going to replace it because a car cannot pass emmissions in Ohio with the check engine light on.
Does anyone have advice on replacing? Best place to buy, etc..
After the sensor is replaced, does the check engine light go off automatically?
Thanks for any help.
