I had a mechanic years ago that had several solutions to such a warning light. I got in one of our older pickups one day and noticed black electrical tape over the emissions light. I started asking questions and was told that they had done everything that they could and still couldn't keep the light off so they covered it up to keep people from complaining about it. When I suggested that the tape was an unacceptable fix, the next solution was to either cut the wire to the light or remove the bulb, whichever was easiest!

 

I may have to go with the tape idea ........ this is dragging on ..... week 3 now.

Ok, took truck in this am and the short answer is now a Reductdant Solenoid is on order ..... expected arrival 2-3 weeks.

This visit was very interesting and wanted to pass this along. The tech had me come back with him into the shop where he hooked up the IDS. He got the codes and connected to the Ford Professional Technicians Site. It then interacted with the IDS reading the codes etc. .... very cool. He then initiated a reductant cycle remotely and you could see the Reductdant Pump pressure and DC current draw graphically on the IDS screen. I was impressed. The pump pressure climbed to 75 pounds and as it was climbing you could see the current draw dropping off. All through the ODBII port and nothing else. This is cool chit.

At the end of the day the generated code suggested the change of the reductant solenoid with no other course of action if the change of solenoid doesn't fix it. That part was not very cool. If the change of solenoid doesnt fix it they do not know what to do next as there is no path on the Ford site. Guess we will have to go back to basic mechanics 101 and start replacing everything else.

Am I bitter about this ..... not so much. At least the truck is drivable and not down. Reduced power yes, which is a pain. Unlike Ricks issue I am not facing any costs related to this. Just a PITA. And yes, I think 2-3 weeks for parts is way out of line.

 

Heh guys. I haven't posted all the happenings on this issue but suffice it to say as of last week I have been CEL free! This took 3 months to get resolved if you can believe it. After replacing the pump, solenoid, tank, lines, another pump, and finally a 3rd pump it is working. They suspect, and I tend to agree, that it was the DEF pump that went bad and then 2 replacements were also defective. The replacements did pump but were not able to maintain required pressure all the time hence the CEL. Must be an issue with these pumps or at least maybe a run of them had something bad in them.

 

dbc001:
Just read this entire thread, and I have to say you seem fairly upbeat for such a terrible situation. I don't know how in the world I would operate if my truck was not 100% for one day let alone 3 months.

With your pumps, do they not test anything anymore before it was shipped?

Thanks for keeping us updated.

 

I'm not sure I would say I was upbeat, however, with the CEL on for polution control I was not as concerned. For 3 months I poluted more than I should have, oh well, I have probably done worse environmental things during that time If it had been down and out I would not have been so understanding.

Do they test the pumps; unknown to me. I can say that the Dealer Tech had his laptop connected and could see the pressure readouts translated into a graph where the pressure was within working levels. With 20/20 hindsight the pressure was slower to build up on the defective units versus the last one installed.
