Check that your air sensor is plugged in/connected to where it should be - this is the most common reason for ETS light coming on
If these two lights come on together then the extra traction sensor is broken and needs to be replaced when the sensor is fixed the check engine light will go off and the ets light will work properly again.
get a scanner
When there is a failure that sets the check engine light, the vehicle responds by going into a limp mode. This means traction control and ETS are automatically turned off for safety and to prevent further problems with the vehicle.
I have a 1997 Chevy cavelier and it say's ets off check engine I'm curious to what would cause this problem and how do you fix it.

Sources of owners manual are Dealer, Salvage Yard, Ebay, and many on-line sites. Check Engine light will come on when the computer has detected a fault in the emissions system. Scanning the computer will list a fault code that will help to narrow down the problem. EST is, Electronic Spark Timing. I have a 97' Chevy Cavalier, and my check engine light comes on every once and a while. When it does come on the ETS OFF light also comes on...did you mean the ETS OFF light? or the EST OFF light? ETS OFF means the Enhanced Traction System. I took my car to Autozone and had them read the computer and it had something to do with a misfiring sparkplug, I replaced the sparkplugs and now everything is fine.
ETS means ENHANCED TRACTION SYSTEM. You need to have the ECU scanned and see what codes come up. With these codes an expert can diagnose the cause of the problem.
ETS is the traction control system. If you want it, you simply push the button to turn it on... you may have hit it inadvertently.. I used to own a 99 Grand Am (another GM product) and constantly did the same thing. Or it could be a fault in the ETS system. As for the check engine light, the first thing you do is find out the cause of it. You can go to any auto parts store and have them read the fault codes with their OBD2 scanner.
Really have to know what year the car is because these problems vary from year to year.
ETS stands for (Electronic Traction System) or as some call it Traction Control. Your Traction Control is simply turned off.
It means your traction control is turned off. Should be a button for it on the side of your shifter.
