Susan Syme, you are probably talking about the Enhanced Traction System (ETS) warning light. It will turn on when the engine computer sees a ...

The ETS light comes on usually in responce to a cooling system problem in Cavaliers. The first thing to do is check your fuses. The Check Engine light always comes on when the ETS light comes on. You need to be concerned with this ETS system first. Usually it is your 30 amp fuse that needs to be replaced. On most cav's the fuse box us under your hood, on the right hand side. There are two fuses that are for the coolent system. Check these fuses first. If the fuse is blown, change it and the dash light should go out. If the fuse blows in a week or so again, then try to read the codes like the guys above say. When the fuse it out, the code reader is just going to say that you need to check your fuse. This is what happened in my car, and my mechanic said it was pretty common in these cars. Good luck.

yes you should. my brother had this same problem a few months ago. and his cavalier would randomly shut off on him when it wanted to. it can get dangerous if ignored. he ended up replacing the tps (throttle sensor) and the o2 sensor and it started running decently

On certain issues that cause the 'check engine' light to come on, the 'computer' shuts off the 'Electronic Traction System' (ETS) to save power incase it is needed due to the issue. The main thing to focus on in this situation is why is the 'check engine' light on. You can go to your local auto parts store and ask them to check what code(s) is being given. Once the issue that is making the 'check engine' light is fixed then the 'ETS Off' light should also turn off.

ETS is Enhanced Traction System is used to stop wheel slip thru reducing engine output. And if the light is on it doesn't mean you will spend x amount of dollars to fix it! It just means that ETS has been disabled because you have a engine problem and the computer cannot reduce power to the wheels because the engine might stall so the computer disables the system! Now some cars come with a switch by the shifter that turns on and off the system because if you get stuck in the snow traction control will keep you from getting stuck

You need to get a scanner hooked up to see if your computer has found an error, for the reason the check engine light goes on.

the ets light will come on when you have a driveability problem it would be the best bet the check the dtcs and fix those for the check engine light first clear everything then drive it.

Just a shot in the dark, but the oil pump may be going bad.

you have an senser bad'' you can un-hook the batter for a few seconds or longer and it will reset the system'''and see what happens''''''my names is james e-mail me back if this helps at'' [email protected] p.s. un-hook the ground cable '''not the pos.'''''

I have a 96 cavalier and if i forget to turn the gas cap until it clicks air gets in the tank and the ck. engine light comes on. So, don't forget that could be part of the problem
