Post subject:  New glow plugs going bad?

Wife calls the other day with a CEL. Truck running find. We met in town and I pulled codes. Got P1263, P0836, P0672, & B2TAE. I'm not sure about that body code but the others seem to point to glow plug #2 (It would have to be 2, not 1 or 4, but 2). I replaced the stockers this past winter with a set of steel ones from IDparts. Before I order a new one and start to investigate warrenty with IDparts I wanted to see if anyone has any experience or issues with the steel glow plugs. BTW, I cleared codes and a cel popped up again this am. It's 70 degrees in the morning here so I doubt they are actually coming on but probably just a current passed to them for start up procedure. Truck starts fine.

I'm assuming you got the Etecno 7v steel plugs? If so, then yes, this has been a common issue. There's a thread here: viewtopic.php?f=5&t=77911

My CEL came on this winter when I had the Jeep in Chicago and it was below 0 the entire time i was there. First, it was my #4 plug, then #2 a week later. The Etecno's I bought from IDparts were less than 5 months old. I just replaced all 4 plugs and installed the intake elbow kit for easier replacement should they fail again. I'll be dropping off all 4 old plugs for warranty testing at IDparts and keeping whichever ones check out OK as spares.

Yes, 7v Etecno

I saw that thread. Not reassuring. I find it odd, and disturbing, that it failed during the summer when they are not really being used. I'll email IDparts and see what they say.

You are not alone, but ID parts will take care of you.

Yep plenty of us are having steel 7v failures. I have yet to contact ID parts but mine failed after about 4 months

I believe that the glow plugs are run in warm weather to help with emissions during start up. Here is a small chart to show the duration when they are on. (Copied from another thread)

Engine Coolant Temperature, Key-ON-Wait-To Start Lamp-(Seconds), Pre-Heat-Cycle-(Glow Plugs On Seconds), Post-Heat Cycle(Seconds)
-30C 10 SEC. 35 SEC. 200 SEC.
-10C 10 SEC. 23 SEC. 180 SEC.
+10C 1 SEC. 21 SEC. 160 SEC.
+30C 1 SEC. 20 SEC. 140 SEC.
+40C 1 SEC. 19 SEC. 70 SEC.
+70C 1 SEC. 16 SEC. 20 SEC.

Mine through the GP#4 bad code this week, also 7v Etecnos that were replaced in February. I checked the resistance through the harness and it shows #4 as an open. Either it went really bad or there's a harness issue. Already have a RMA from IDParts just in case.
