Any other guesses as to why I would have an intermittent CEL for glow plugs on my 06 T1N Sprinter?
Trouble codes are:
PO671 - cylinder 1 glow plug circuit/open
PO672 - cylinder 2 glow plug circuit/open
PO380 - glow plug / heater circuit A
I believe I've had other CELs for other cylinders at times as well.
The engine is an OE reman with 65k miles on it so the glow plugs are low mileage and when removed and tested with a multimeter they all show less than 1 ohm resistance.
I did not test my old glow plug controller, but I just went ahead and replaced it with the newer version.
My CEL remains. It doesn't affect the way the vehicle drives and doesn't seem to affect cold starts either, but why do I have this insistent CEL? I've put up with it so far but would prefer to save the CEL for other "real" issues I need to know about.
