Ok - so I have a few things going on...and after reading a bit out here I think the oil gauge issue is the sending unit (gauge is pegged all the way). However my other issues, I am not sure about: ABS and Traction Control lights come on, the "dinger" goes off to alarm me when they do come on which is after about 5 mins of driving. That has been happening for about 2 months. I have just noticed a day ago that another dashboard light comes on....the "Brake" light comes on. (just to make sure we are on same page, this should be telling me my emergency brake is engaged). The mileage for this car is at 151,xxx. The model is an SE. Any information is greatly appreciated.
Oh...two other items...no heat or very limited heat and 4 of the 8 buttons for air control don't light up...sounds like a fuse??

Thanks

I'm with you on the sender for oil pressure.

Double check your brake fluid level, it can also cause the light to come on.

On the traction/abs, that may be related to the fuild level if found low...but it could also be a bad wheel bearing.

I had the ABS/Traction/Brake light issue too. I replaced my front brake pads and rotors and it has not happened since. Mine were warped beyond funny, and I think it was messing up something. However, based on recent experience, if they go on again, I'll be on the wheel bearings.
