I have a CEL light on all the time...wished it can go away since my car is stock now...but it feels weird when it's not there from resetting the battery.
had my first emissions test this year, and now I need it every year (because I live in a ****ty county, if I lived 200 yards to the west I wouldn't have them as often.) So, I need to keep the light off, they just plug it in, they don't put it on the rollers anymore. But, when I had my CAI installed it would come on for a few miles and turn off, and then backfire the next day when I start up.
P0131 - O2 sensor circuit low voltage, Bank 1 Sensor 1
P0135 - O2 heater circuit, Bank 1 Sensor 1
P0138 - O2 sensor circuit high voltage, Bank 1 Sensor 2 (Usually low voltage code)
P0141 - O2 heater circuit, Bank 1 Sensor 2
The CEL has been on for at least 2+ years now. I am working to resolve this issue, however the problem seems to evade me. Maybe I just need authentic Mobis / Hyundai O2 sensors instead of the premium Bosch sensors I have been running.

always on. actually with all my mods, four of the lights are on even though there are no problems. i like it. sometimes i talk to it. i say things like " you ...... little ... .... light. why the .... won't you ....... go away and leave me with a little ....... peace from your ...... little shining ...... self." my cel is my best friend. never yells at me, never talks back, good listener, and is always there when i turn on the car.
Well, im my car, not only do i have a CEL light with (4 faults, runs fine!) i also have the airbag light on too. So there. Booya. I win.
CEL is on probably due the the exhaust from the flex pipe back not connected ...
Air bag light was on ... removed the bulb.
my car thinks the hatch is always open, so THERE!! BOOYA BACK DUDE!
