SOURCE: check engine light stays how to get it out

You must clear the code . It can be cleared with an OBD2 code reader and some vehicles will clear by leaving the battery cable off for a while.

Service eng light,abs light,trac control light all stay on


sounds like possibly one of the sensor connections is disconnected possibly when oil was changed maybe one of the plug ins were knocked off or partailly disconnected, check all plug ins under hood most likely a plug in on the abs unit under the hood,(usually has lines running to the master cylinder) possbly plug in onthe master cylinder also.

Final drive speed sensor causing Trac light and rough shifting. Metal dust on the sensor. Have the transmission filter and fluid serviced. This should have been done at 60,000 miles. You may get an ABS light too. Service the sensor. Perform an OBDII scan for stored faults.

Abs light ,trac off, and service engine soon would come once in awhile, but now its on all the time. my turn signals sometimes won't work either.


These are differnt issues. The Trac off light is on because the ABS is on most common reason is because of a bad abs sensor which is part of the wheel bearing unless there is any damaged wiring.Your check engine light is on for another reason there could be many possibilities.The turn signals may be the hazard switch or turn signal switch. You should take to a repair facility that has a scan tool to tell you what are causing the abs and engine lights to come on.

Sounds like you have a bad wheel speed sensor. You need to have it scanned. Since it's been sitting, it might just be a bad connection to one of the speed sensors.

It is possible that you pushed the ETS button. The 'trac off' light comes on in my Grand Am when this is pushed.
