Crazy check engine light
Whenever I pull a sensor such as MAF or a coil the check engine light doesn’t come on. Instead the traction light comes on instead. However when I use a scanner a code pops up but no light.. when I turn the key to the on position I can see the check engine then but not when a senor is pulled...- Vaughn-Vaughn
