Anyone had the engine malfunction light come on then go out a couple of starts later? I thought once it stored a fault it stayed there until you cleared it.
Do you own a
DealerTool? The code should be in memory even if the MIL is no longer lit. The light might only indicate when the problem happens, but the reason should be stored in memory that you can retrieve and erase with the DealerTool.
In some vehicles, the MIL (malfunction Indicator Lamp) does different things with different problems. Some will latch on even after the problem is gone, some go out instantly when the problem is gone. Some require so many restarts to clear. Your best bet is always a shop manual to explain the way the different codes act. But regardless of the MIL being lit or not, the code stays in memory until you erase it.
