Why is the check and VSC indicator light on?

Question

Check and VSC lights stay on in my Toyota Highlander 2007; code P0300

Answer 1

HI there

This code, P0300 is for a random multiple cylinder misfire. This code can be caused by several things ranging from spark plugs to low fuel pressure. The VSC light is on as a default because of the check engine light. Once the check engine light is off, then the VSC light should go off as well. Here is some more info on the causes of this code.
