Hello and welcome. My name is Jerry and I will be happy to assist you today.


There are many areas in the power train controls that will make the light come on or flash. You will want to have the codes read to see what area the problem is in. Normally Autozone will read the codes for free and even tell you the area of concern, as well as clear the code out of the computer.


The code(s) can only be cleared with a scan tool. Not only a parts store can clear it but any shop with a scan tool.


When we know the code(s) then we will have a better understanding as to what the cause may be.
