Ets off light comes on then after awhile check engine light comes on but when i turn the car off the lights go off. the lights come on and go off. when ets light is on the car struggles to shift when light goes off the car runs fine. help please.

The ETS light is the warning light for the Electronic Traction Control. Check Engine light indicates there is a problem with the emissions system. Take the vehicle to Auto Zone, Advance Auto Parts, O'Reilles, or Pep Boys and have the ECU scanned to see what codes comes up. The code will tell your what part is being effected.

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.

Hello there
let me try to explain it the best way i can

If you are talking about the light coming on when you are driving in slippery conditions, this is normal. If you are talking about it staying on all the time, the ets is either turned off or you have another problem. Let?s take a moment and explain why the electronic traction control which is called Enhanced Traction System (ETS) warning light will turn on when the engine computer sees a problem. The ETS system monitors wheel speed via the Anti-lock Brake System (ABS). If the ETS system sees a wheel spinning due to snow, ice, rain etc., the ETS computer sends a request to the vehicle?s engine computer to reduce torque. The engine computer responds with a combination of strategies. In the engine computer?s bag of tricks to stop wheel spin it can perform any one or combination of the following; cut fuel off by trimming or turning off fuel injectors, ****** the spark timing or up shift the transmission. In the days of old we just let up on the gas pedal. Now the computer does it for you. If you have an engine running problem it is more of a problem than you realize. The engine computer is the high command center. The engine computer will work and respond to information from the other computers in the vehicle. But in the event there is a system or running problem that the engine computer is responsible for, ?it will? lock out all of the other vehicle computers. If there is an engine running problem that causes the engine computer to store a code and turn on the ?Check Engine? light guess what computer doesn't talk to the others? The engine computer. The ETS computer gets all put out when this occurs and turns its warning light on in protest. So, there you have it. If the check engine light is on the ETS warning light will come on as well and the ETS system will not operate until the engine computer problem is corrected.

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

Check engine light is for telling you that there is A problem with the fuel injection or emissions system, Most of the time there is no major problem to really wory about. ETS is the light for the Enhanced Traction system (traction control) This is not A vital component of your car.

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.

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.

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
