RESOLVED 🛑 STOP sign on instrument panel

[GJohnson]

This is a 2106 5055E cab tractor with 12x12 PR transmission with 800+ hours bought at auction that needed a rebuild. I drove this tractor and even loaded it after purchase. I have no previous history for it. When I got it home, it barely had enough compression to crank, but had no lights on the dash at all. I ran it for a few hours, blowby and gurgling oil from the valve cover. Obviously the rings were allowing compression to pass. It didn’t get hot or have any stored codes. The rebuild is done. Upon cranking it after rebuild, it started right up. However, I now have lights and codes. Codes include 102.04 = manifold air pressure sensor low voltage. 105.03 = engine inlet air pressure temp sensor voltage too high. 1569.31 = engine protection. This last one says (internet says) it’s in conjunction with other codes. Lights are STOP, DPF regen says it needs a parked regen as the button is flashing, engine information indicator is on as well. Engine is now derated to 1800 rpm. Again, no lights or codes before the rebuild. Am I now flowing too much exhaust pressure than what the computer was accustomed to reading? Because it’s derated, do I have to involve JD? I know there are some smart guys on here. All of your help is appreciated!

Did you clean/replace/bypass the DPF?

 

[GJohnson]

No. As I said, it wasn’t asking for anything before the rebuild. I didn’t want to change the parameters unnecessarily as I realize how sensitive sensors can be.

Being that it was running so bad before the rebuild, the DPF might be plugged. Also, did you swap out the fuel for known good fuel. If not, you don't know if there is gasoline or even paint thinner in there.

It ran great, but had no power. The fuel in it has been replaced with fresh diesel from my tank with a filter. Fresh coolant and new oil. Fluids shouldn’t be my issue as they’ve all been changed. All of the filters have also been changed, even the cab filters. I only ran it long enough to ensure the coolant system was fully flowing through the heater core as it is above head in cab.

 

[ruffdog]

Your not gonna have any power if the DPF is plugged like this. Does the exhaust sound and feel very muffled?

 

[GJohnson]

It had no power before the rebuild. It has plenty of power and compression now. Except it is derated. Never having a tractor with DPF, I can’t say what exhaust flow is or should be. It sounds right, but that means nothing really as I only have this tractor to judge that from. But again…it did not want a regen or have a stop prior to rebuild. Looking at the pic, my dpf filter looks nothing like that. It is white inside and I can see the ceramic quite well.

 

[ruffdog]

You might have to have a tech hook up to it with the shop computer and check the codes and parameters. Keep us posted.

This one looked clean until this happened....wow.

If I could delete this, I would. I’m not looking for DIFFERENT answers, just answers. So far, only two, ruff dog who was trying his best to be helpful and you, worried about where this is posted. Do you happen to have any input about the issues?

 

[ruffdog]

What chance is there that during the repair some wires were pinched? The tractor may have sat for a while so mice damaging wires may happen too.

 

[GJohnson]

Definitely not a mouse issue…but there’s a chance of damage to wiring simply from moving them to take off the head. I don’t think that’s the issue, but it’s possible. As I said, I ran it long enough to get antifreeze up through the heat system. I didn’t allow it to idle below 1200 rpm until shutdown. When it was running, I was outside of the cab for a bit, feeling exhaust and looking for any issues. That’s when the stop light illuminated. The engine light was on as I had two codes unrelated (I thought) to this issue.

Have you tried disconnecting the battery for a few minutes to see if the codes will reset? On the 9530 I used to run it through a couple of the stop sign codes. Don’t recall what they were but doing a power cycle reset them. May or may not work for the codes you are receiving.

Yes, worth a try.

It needs to go to the dealership and have the codes cleared.

 

[GJohnson]

Resolved…manifold sensors were not plugged in after rebuild. Entirely my own fault. all is well with this tractor now. Thank you all for your input. It’s not always necessary to involve dealer. We can still lean on one another and that is appreciated!

Thanks for bringing this full circle.
