00 SE Problems

I got a problem with my GP SE. At any given time, I'll be driving and my ABS light and my Trac Off lights will come on at the same time. And just this morning, my Service Engine Soon light came on with them... has anyone had this before? If so, what is it and how much is it going to cost? Any help would be great! Thanks!

Your ABS/Trac light could be a bad speed senser/Hub. If this is the case the whole hub assembly would have to be replaced. Common too is the wiring to the senser sometimes corrode which would be a cheaper solution than 500.00 a dealer charges for a senser hub replacement. As for your Engine light Autozone or most auto parts stores can scan for a code for free and you can post it here and someone can tell you what it's for.

I agree with JonJon that the trac off/ABS light is most likely a bad hub bearing. The check engine light is unrelated, so take it to Zone or Advance, and they'll scan it for free.

Alright.... heres what I got...

I took my car to Auto Zone, they said that there were 2 codes, and they were for a small emissions leak, caused by my fueling with the car on(which I did, but came on a few days later... hmmm), a missing O-Ring on my gas cap. In other words, something minor and should go away in a few days.

Now... whats this hub bearing gonna cost to be replaced? And I hate when crap like this happens. I'm a volunteer firefighter, and can't have it down for a long time...!

The trac and ABS light both come on to indicate a problem with the WSS (wheel speed sensor) which is incorporated in the wheel hub. The only way to replace the sensor is to replace the entire hub assembly.

However, don't worry about that right now because usually the problem is wiring to the sensor. If you jack up the front end of the vehicle and turn the wheel clockwise to the lock you can get access to the driver's side wire harness. Pull apart that connection and make sure it's not full of moisture/grit. Blow it out and put it back together and then trace the wires to the sensor and then away from the sensor as far as you can. If everything looks okay go check the passenger side.

There are four WSS' in all so it will take some time to check all the wiring or I believe if you have access to a GM powertrain scan tool it should tell you which WSS is causing problems and then you can go straight to that one and check the wiring.

One other thing you can do to the wheel sensor(s) is ohm it out with a multimeter and see if it's in a specified range of resistance. Undo the electrical connector and go across the 2 pins on the sensor/hub side.

Here are the specs:

Rear wheel sensor (1030 - 1180 ohms)

Front wheel sensor (1020 - 1137 ohms)

If outside of this range it's flaky. Also, maybe you can try to duplicate road conditions by using a rubber mallet and tap (not too hard) on the hub to see if it breaks continuity.

Also... forgot to mention, when I turn the wheel at low speed it makes a whining noise and when I turn harder, it mage a light grinding noise.... think theres a connection??

yes, there is a connection. The noise you are hearing is the hub bearing. Make sure you don't buy a cheap "white box" Chinese hub bearing, unless you want to change it again soon.
