Question [B]94 LS400 (150K miles) - Trac Light on Instrument Bd. Going On in Dry Weather?[/B]

My Trac light on the Instrument Board has recently started to come on infrequently when I am in dry weather with dry pavement. Just started noticing this in the cold weather in Wash DC this winter (20 degrees to 50 degrees). Could come on when I start the car up and not go off for an hour or two and then when I stop and drive it somewhere else in the next 1/2 hour, it does not come on at all. Or could come on after Ive driven it somewhere & stopped, then it might come on when I am going somewhere else within a half hour, in dry weather conditions, but cold weather conditions? Also, seemed to notice gas mileage has decreased, could this traction sitiuation actually be on for an hour or two in dry weather and be using more gas?

Has anyone experienced this problem and can you tell me approximate cost to repair at dealer? Thanks for your help and advice.

I had a similar problem like this. The dealer said the Traction Actuator was bad and quoted me something like 2k to fix. I was told that if you buy the throttle body at a salvage yard it comes with the trac actuator. You might want to try and confirm this. I never had mine fixed as I don't prefer driving with this option anyway. Good Luck.

We had a similar problem. We took it to the dealership and it was an oxygen sensor. Cost about $300.00.

On my '91 LS400, topping off the brake fluid fixed the problem of a trac light flashing off and on! Good luck--cheap enough fix if it works!

Thumbs up Trac

I have the same problem. It only happens after the second and each sebsequent start thereafter. I referred to this site a couple of years ago. I was told to drive more than 15mph and simply turn key off then back on while coasting (keep gear selection in "D"). Works every time.
