My 2003 3.8L had a broken exhaust, right side above the catalytic.Before it wasfixed the O2 sensor set off the SES light, now how do I reset the SES light without paying $90 bucks to a shop with a computer?A few folks suggested 1. Disconnect the battery, 2. Drive it for 3 days, 3. It has to be put on a computer...

Any help for a new guy?

If the problem is fixed it should realize it...if not disconnect the batt

 

OK, today when I get home....a hundred miles driven and it hasn't realized it yet...I'll try the battery. Thanks

 

You need to leave it disconnected for about 15 min. for the computer to reset it's self, this will also reset the idle so it might be a little rough the first timeback on.If the code comes back right away then you have a sensor unplugged, if it takes a day or 2 to come back then you have a bad sensor/have not fixed the problem.

 

go to autozone..... tell them you need your sensors checked.... they will tell you what you already know.... ask them to reset it... they should for free... unless the guy is an ****

 

Thanks to All
The battery disconnect worked for now.
I got bored at work so went and tried it. For a five minute idle the SES light did not come on after reconnect.....

Thanks again....

 

If you have a county requiring emissions inspection, they connect to your PCU and they know that it is not ready unless you drive about 100 miles.

But on the other hand if they just look for a SES/CEL then you're good.
