00 Vette Losing Power Low traction?

**Jerry's 99SS** · 05-01-2010, 10:17 AM

I have a 2000 Vette. This has a magna charger on it. Last year I had the supercharger rebuilt and it was lost power sometimes. We contacted Magnuson and they said if the harness is to tight you can lose power and not run right. We rerouted and lenghthened the harness. A few weeks ago I turned off the traction control for a second. It didn't seem to disengage when I put it back on. Then as I was driving I lost power and the low traction light came on. Then it flashed to loss of power. I made it home unhooked the battery and eventually got it to reset with the reset switch and messing with it. It then ran fine for about a week then it happened again. Pulled battery and tried to reset (I saw some message about wait 10 seconds) finally got it to reset. Runs great now. Any ideas, since I have no way of knowing when this will happen again or where.

Thanks for all the advice in advance!

sounds like the traction control is kicking in when it shouldn't. You'll need a scan tool to monitor/record the event and determine which wheel speed sensor isn't reading correctly.

Cutlass, that makes sense. I don't have a scan tool can I rent one or do I need to buy one of the expensive units? If so which do you recommend?

Thanks again!

actually I just remembered a technique using a multimeter that I've used on GM SUVs before for unwanted ABS activation.
So your problem has to be one of the rear wheel speed sensors.
unplug one sensor and put a multimeter across the two terminals. measure AC voltage in millivolts while spinning the wheel clockwise by hand as fast as you can (at least one revolution per second). On the trucks I check, its usually reads around 300 to 350 mV AC on a good one and noticably less on a bad one. Replace the one that reads lower.
