Vsc code c1336

That code relates to a crankshaft position sensor signal. It you have a check engine light come it disables the VSC and Trac system. Until you get that sensor fixed the VSC and the TRAC system will be inop. So whenever you have a check engine light come on that is what you will see. Even though you cancel the check engine light the fault still exists and the VSC/ TRAC light will come back on. That is a sure way to tell that something is wrong.

Toyota 2001, 4-runner, 158k...the check engine,VSC/TRAC, and TRAC OFF warning lights came on at the same time and have stayed on...what could be the problem?

VSC lights always go on during a "Check engine" period so just get the engine fault code and DIY or go to a TRUSTED mechanic (or someone you trust goes to).It is likely an emissions problem.

The VSC, Check engine and, traction control all came on today at the same time for no apparent reason?

Anytime the Check Engine light comes on, you will find that the VSC and TRAC OFF lights come on as well. Supposedly, it's in order to lighten the load on the car's computer when things are going wrong. Find out what the Check Engine code is (for free at your local Autozone?), and get that taken care of before worrying too much about the VSC or TRAC OFF lights.

When the vsc trac light comes on my 2003 Toyota 4 Runner, what does that mean?

As long as it does'nt stay on it's doing what it's suposed to be doing which is saving you from going out of control. It'll come on more often if you drive like hell, run with low tracktion tires or worn out ones and if the air pressure is low. If your tires have over 80,000 miles on them even if the tread is still good their bad tires as their skating along and the trackstion system is working hard to keep the car under control. If the tires aren't al the same size it'll do it to. ( fronts worn out backs still with tread.) Mis matched tires too. Ifthe light stays on other light's are bound to be coming on too the ABS light the brake light, and even the engine light as their all involved in traction control.

Check engine light vsc light and trac off light

VSC and TRAC lights will come on any time the check engine light does to reduce engine load. As such these lights being on may have nothing to do with the why the check engine light came on.

If the check engine light is on, a trouble code(s) has been stored in the computer that points to the problem area. The dealer should have read this code(s) to come up with what was wrong. Did the dealer give you a sheet with the trouble code number on it?

The engine may have variable valve timing, if it is not working the engine will revert back to a fail safe condition so that no damage will occur. But it will not be running a peak performance. Or it could be something with the engine timing system.

If you want to do your own checking, start calling autoparts stores to see if one will read the trouble codes for free, it is an easy job. AutoZone will read codes for free.

Hope this help.

Toyota 2001 4 runner vsc lights on and trac off.also check engine light on.what is the problem?

Those lights always come on whenever the check engine light is on.It could be from the gas cap not being tight enough or an air hose in the engine compartment coming loose. I recommend bringing your vehicle to someone that can read the codes and reset the lights for you. The codes will narrow down what the problem really is.
