Welcome to just I'm here to help you and your 100% satisfaction is my goal.

On this vehicle you can reset the PCM like disconnecting the battery cables and touching the cables together for 30 seconds this will completely discharge and reset the module . If you immediately get a service engine soon light that means there is a problem present in the system and must be fixed
