During snow my Traction Control has to pop on and off as expected. A few days later, when the snow is gone, I take a trip down the highway and the CEL lights up with an O2 sensor code. I pull over and reset the computer and carry on.

I'm thinking the Fuel is dumped without burning up when the DTC kicks in and then muddies up the sensor...

I'm also wondering if there is something I can do to prevent this in the future. Should I just clean the sensor after each snow storm?

thoughts....

Thanks

Ill ask my Toyota / Lexus buddies and see. Is there any way to shield it? I don't have traction control on mine lol

Thanks for the reply.

I do have the switch to turn it off, and I do often, but with a rear-wheel drive in the snow no way am I driving around others with that thing off.

Interestingly we had several inches this past week and it was kicking on and off every time I gave it fuel. However, the snow is now gone and it hasn't popped a CEL this time. {fingers-crossed}

One of my friends said it could be the traction motors, possibly shorting out or just not working.
