This morning I started the car with the remote and went out and put the key in a procedure I've done hundreds of times.
This time, however, the Check Engine Light and the Elelectronic Stability Control light remained on.
The car drove, but very slow, I think it is a safe mode of some sort. Maximum RPM was about 1200. I drove around the block, came home and parked on the street and shut the car off. I restarted the car and it is now back to normal except the CEL is still on. Drives fine and the ESC light is off.
Here's what I think may have happened. Last night I drove home in a slushy wet and slippery snow. The ESC was never engaged, but the ABS did a couple of times. I parked the car and, of course, the temperature remained below freezing. Something may have frozen or otherwise affected the wheel sensors for the ABS and ESC. The short drive was enough to free it up.
My question though, would that put the CEL on? I'm also assuming it has to be reset with an instrument by a repair shop or possibly the auto part store.
Any other ideas?.
