CEL Glow Plug Circuit

[f_250pstroke02]

Popped the #2 cylinder glow plug circuit code and need a little insight. What does this mean? Glow plug isn't coming on or going off? Also, I now have a light haze of white smoke at idle and alot of white/blue smoke on hard acceleration from a dead stop. Any ideas?

The glow plug is probably dead. You can check it with an ohm meter. If you see a short, or about .5 ohms the glow plug is good. If you see open then the glow plug is dead.

Thanks Dave.

Any harm in driving her a little bit? My other truck is still in the shop and does anyone have an idea on the smoke? Talked to a Ford tech and he thought it might be the EGR cooler

Drive it. Plug it in if it is cold outside. I think I would agree with the Ford Tech in that it may be the EGR cooler. But I have no experience with this.
