2011 camry check engine ligth flashing

Then you need to at least get the codes for both the check engine and the traction control systems. Could be something as simple as a bad connection or ground in either system.

A flashing check engine light is warning you that the engine is misfiring and damaging the catalytic converter. It needs to be looked at sooner rather than later. Most likely you need a tune up. The traction control light is a different issue. Hope that helps! Jim

When a computer turns on the CEL, it cancels cruise control and traction controls by default. If the flashing CEL was sudden, you might just have a defective gas cap, or one that isn't properly tightened. Or it might be an EVAP problem where the pollution controls have a fault. You don't know cars, so just do what you should do anyway. Check the gas cap or just buy a new one. If that doesn't fix it, take it to a mechanic to check out and repair.
