View Full Version : Check Engine Light Turns On and Off

Lately my check engine light has been turning off and on intermittently. Does this mean anything? I have a DAD and after the last time I ran a diagnostic I didn't clear the codes so it makes sense that it would be on. I did get two P2356 CDI Control Unit Codes with the last diagnostic. Does this have anything to do with it?

The van runs great despite the intermittent CEL.

Thanks everyone!

Dan,
Since you asked....

That code with 008 sub fault is CDI control unit "Internal Fault". That sounds scary.

You indicated that you've changed the Intake Temperature Sensor and it seems to be running well. I would read/record all the codes and do a reset to see what, if anything, returns. Maybe the temp sensor being a bit wonky affected things?

Of course the real answer is to contact Doktor A.

P.S. - I trust your fully loaded trip continued to go well.
