Engine light and traction control light have come on...

[Brentismaximas]

My 2012 ZR6 traction control and engine lights have both come on. They stay on while idling. And when I drive it the traction light stays solid and the engine light flashes. And now the car kind of shudders when accelerating at lowish revs.

Has anyone seems this before?

What happened before the lights came on?

My 2009 Presara traction and engine lights came on yesterday. I turned the engine off and then back on, the lights returned. I left it turned off for an hour. When I turned it on again the lights returned. I took it to my mechanic who wasn't worried. Apparently the traction light can be upset by dirt or small iron based pebbles sticking to the magnetic sensor. The engine light comes on in sympathy with the traction control sensor. My mechanic plugged in a diagnostic tool which showed nothing wrong although he wants to do a proper diagnostic next week. Today when I started up the lights didn't come on and in an hour of use they stayed off. I let you know what my mechanic finds out later next week.

Check out previous topics on this forum. It has been discussed at length before.
The TSC light and the engine light can come on for many reasons. In my case it has been the traction control with wheel slip when reversing on slippery ground.
After a few start/stops the problem rights itself, and the lights go out - until the next time I reverse in a tricky situation.
