General Maintenance & Repairs - Engine light on again

I went and got my wiper switch looked at the one day at the dealer and also was going to have them replace my one O2 sensor on my car since the SES light came back(the SES light went off about 3 months ago). The dealer ran a scan and told me it was throwing codes for both front sensors and the cat converter too. They deleted the light and told me to run it some so I held off on getting the one O2 sensor that was bad in the spring. They told me it was about the wires were going bad or wasn't keepin temperature. Should I even replace them or just leave them go as the car is excempt from emissions but I have to have the light off to pass. I was thinking of just pulling the battery for a few minutes to kill the light. Thanks

If you are getting front O2 sensor codes, you need to replace them. The front o2's are used to properly fuel your car.

If it's the rear o2's, then don't wory about it

Dont ignore it by doing the quick fix, your car is telling you something is wrong so fix the problem correctly, you'll be glad you did.
