Check engine after drifting
 

Hi,

I've encountered a weird issue.
I was drifting with a low RPM (¬4K in AVG, sometime hit 6-7K for "fixes" but in general around 4RPM) for a relatively long time (maintained ¬2-3 minutes drift with couple of seconds stop between each drift, for around 20 minutes) and suddenly check engine light was on.

I'm after oil service, checked oil level - was good,
oil temperature was only slightly higher than regular drive (~around 140) .

Tried to turn the car off and start again, check engine was still on.

Turned the car off for around 20 minutes, started again - the light went suddenly off.

Any ideas what can it be?

Thanks,

probably something a code reader can tell you about

The car keeps track of differences in wheel speeds. When you put a car on a dyno where the front wheels are not turning, but the rear wheels are it'll often throw a check engine light.

This could be a similar to the situation you've described where you were drifting and the front wheel speed was probably different than the rear wheel speed.

Typically this check engine light will self-clear after a bit of "normal" driving where the wheel speeds match.

There are at least 2 ways to determine if the check engine light is something to worry about:

1) Get a tool that will let you read the codes, and use the codes to figure out what is inducing the light.

2) Drive the car for a bit, if the check engine light is due to the differences in wheel speeds as I noted above, it'll auto-clear the check engine light after driving the car for a bit.
