Check Engine Light, Running Great
Hello,
Got my first check engine light in my 97 sc400 w/180k miles. Car is running fine. Know it needs Brake lines, lower control arm on pass side, and a serpentine belt change(common pwr sterering leaking occurring finally)
Just passed emissions 8/1, no smoke, smells, or any signs of issues.
Did fill tank with $50 yesterday, normally only put in 15-30 here and there. Heard gas caps usual culprit. I took it off and put it back on, no change yet. Should I be worried in meantime or am I good to go for now? Having the issues above repaired in coming weeks.
Thanks guys

If it was the gas cap the CEL would go off after a few days of driving it. You may also want to "reset" the ECU. Unplug your Negative battery terminal for a few minutes, then put it back on. Drive around for a few miles see if your CEL comes back on. I would get your codes read first like mentioned above tho because there is a code that is related to the gas cap.
Are you sure you put the right gas in?

Okay, so autozone checked code. turns out bank 1, sensor 1 O2 is bad. What do I search to find this particular one, where located on car, and anyone have a good barely used one? Will change out all 4 next year if I decide to keep car but want to fix temp now.
Thanks

When I had the same issue I went ahead and got a scan tool to look at everything to make sure I replaced the right one. the one I got hooks to the laptop and its just plug n play. it gives a ton of information. things you don't think abut like the tps sensor and what-not.
I recommend doing this. it'll save you time instead of replacing a working O2 sensor, finding out you did the wrong one, and then redoing the job until you get the right one.
