I've been searching and couldn't find anything that would be the cause of my problem..
It's been happening ever since 2 weeks ago.. I'd be cruising on the highway at 65 and randomly the epc and traction lights would come on simultaniously. Also, I can't rev over 3500 and can't go over 65, guess it's referred to as "limp mode." They would stay on until I stop, turn the car off, and restart it after a minute. If I do it too soon only the esp goes off.. and I'd have to restart again to get them both gone. Then it's all fine and dandy, usually.
Now, up until yesterday I had a cel for an o2 sensor.. sensor 1 bank 1, and a bad cat. The epc/traction light happened while the cel was on.. once or twice while highway driving. Now, these lights haven't come on under 60 mph.
I picked the car up from the dealer yesterday. They had replaced the faulty cat, and the o2 sensor cel went away due to the cat being replaced. They had also replaced my bad wheel bearing, and I guess we had a recall on the brake light sensor.. so they did that free aswell. (I did this myself about 5 months ago) I had lights with mine only recently and with theirs.
So no more cel's, but during highway driving, 65 mph, the epc and traction came on again twice. restarted and they went away. There was a parked time between them and the engine had cooled off.
My rear pads are getting low, and will be changed very soon.. that has thrown no lights of brake faults, so I don't know if that would cause any problems.
Now, do you guys think I have an underlying problem with my epc system? Maybe a connector going bad, or just has bad contacts and the highway driving are shaking it enough to cause it to throw the lights and cause "limp mode"?
I have a V-Checker Scanner - Pro from ecstuning coming.. we'll see if it can dig anything up.
Thanks in advance guys.
