It might be that you did not tighten the gas cap enough.
You must have an engine scanner to do that.
That REQUIRES an ENGINE SCANNER to do that.
You use a scan tool after repairing the cause of the code that turned the light on.
it depends on the engine but check where the lower hose ends closest to the engine
Yes but, if the light is flashing no.
NO!!!
See link below.
It is on because the ECU has detected a problem with the emissions system.
Every sensor on the engine and transmission can cause the light to come on.
steering weel collumn, check autozone
Check engine timing
It will run, But not right and the check engine light will come on. It needs the converter.
