Check Engine Light
|
Sign In

Was out of town with the 2004 Dodge Stratus 6 cylinder and the check engine light came on.
Stopped at a local mechanic and he checked it out with his computer. He turned the light out and said it was the O2 Sensor. He couldn't change it but said it would be ok to drive it home and have a local mechnic look at it.
I drove it home 120 miles and the light stayed out.
Could his computer have had a false reading or could the O2 sensor have started working once again?

The 02 sensor code do you know it? Some vehicles could have much as four and they do get exspensive but I would drive the car until it happens again

No, I don't know the code.
Is it true that the only consequences if the O2 senor goes out is the fuel will burn richer resulting in poorer gas mileage.
I don't want to get stranded waiting on someone to fix it.

The O2 sensor determines how rich or lean the engine is running so the computer can adjust the mixture so it will be as efficient as possible. The light could have come on due to a small mixture adjustment that threw the parameters just a little outside what the computer wants to see. It is possible the light will not come on for quite a while. Please have the codes read if it comes on again and post the EXACT code number for us. If you can find a place that has a high end scanner, you can pull up the erased code.

Hey W2O, what you thing about the aftermarket 02 sensors, I worked on a 2001 KIA and went thru 4 of them, and finally used a OEM from dealership and it worked.

You stated my stand exactly. The aftermarket sensors just have to fall in the parameters. Sometimes they are right on the edge of failure. And then they fail qiuckly, or immediately if the vehicle is not running absolutely perfectly. I do OEM on all ignition and emission componets.
