Weird cel light, need help

This started yesterday. When I pulled from my driveway, the cel came on for a sec and went away,(it wasn't flashing). For the duration of 20 miles it came on about 9 times, only for a sec. While it's on I feel I lose power. If I'm at idle and the light comes on, the car dies. I can't pull the code due to it not
staying on. Plz help

Re: Weird cel light, need help

Codes get stored until you reset your ecu....
More than likely you have codes stored, unless you've unplugged the clock fuse or the battery.

Re: Weird cel light, need help

P0420 (cat or 02 sensor) and p1259 (electric load detector). I dont understand why the cel goes on and off tho?? How should I go about this?

Re: Weird cel light, need help

I've seen the light stay on when it stores, when it's pending it doesn't, when it's a misfire it flashed. This symptom is one I haven't seen. It stays on only for a second (while it's on for that second, I lose power) it does it about 9 or 10 times a trip. I understand that it stores in the ecu, but why is it on and off for a second while I lose power when it's on ONLY for that SECOND that it's ON?? I don't think p0420 would cause this. Only thing I can conclude to is a faulty wire in the o2 sensor and it's related to p1259??

Your posts are useless.



op: check your grounds, replace your secondary o2 sensor and test your battery and alternator

Re: Weird cel light, need help

What kind of code reader did you use?

I ask because my $49 generic one gives possible causes with codes..one time a random misfire code mentioned egr, load detector, and bunch of stuff...it was my distributor cap and rotor...

Now if your cat or 02 sensor trigger a code your car changes up tactics to try and keep emissions as low as possible.
The obd system is a save the planet gizmo designed to lessen your carbon footprint by making the engine combust fuel as efficiently as possible. It also happens to be a diagnostic tool used by many to tell when something is going bad in the induction or exhaust.

Anyway, if your engines obd thinks the cat is clogged or receives weird voltage from the 'monitors' it changes the air/fuel/fire mixture to do what it's designed to do...make your car run like $hit so you'll fix it.

Re: Weird cel light, need help

Alright fellow luders, disregard most of the things I've said. Sooo, i found out that if I had my scanner or any scanner pluged into the obd2 port, the symptoms stop (lost of power when cel light comes one/no cel light at all) and there's no pending codes for the past 50 miles I've driven with the scanner pluged in. The second I disconnect the scanner, my cel light flickers and lose power when it's on for a second duration at a time. But I still have no pending codes.... WTF!!!!!

Re: Weird cel light, need help

Why would you drive 50 miles with your scanner plugged in?
