4052M keeps showing STOP signal

Our John Deere 4052M is 3 yrs old and has been running hot (literally) after brush hogging for about 30 minutes I get. STOP signal and have to shut it down. Took it in a week after itís warranty last year and the only charged me $200 to check codes. He cleaned the A5501 Pin 26 signal wire to the fuel pressure sensor but that didnít help for long...anyone else have this problem? What else should we check?

Re: 4052M keeps showing STOP signal

We need some more information. You said it is running hot. Do you mean the gauge is running into the red? Have you checked all the basics? Radiator and coolers clean, belt tight, coolant full? Since you have multiple coolers(radiator, aftercooler, oil cooler, etc, it can be challenging to clean between each one. they can look clean from the outside at a glance, but dirt can be packed down in the fins and air can't get through efficiently. You said dealer pulled codes. Do you know what codes they found? Was it a fuel pressure code since they cleaned connections for fuel pressure sensor? Fuel pressure issues should not cause overheating typically. Have you tried checking engine temperatures with an infrared thermometer? Maybe it is not truly overheating and has electrical issue in gauge/sender circuit.

Re: 4052M keeps showing STOP signal

How tall of grass are you brush hogging? I've found it's pretty easy to get the radiator packed full of grass pollen/seeds in the right conditions.

Re: 4052M keeps showing STOP signal

To jd 110 or anyone that can HELP us!!! Our original post from 2-3 weeks ago explains a lot of our issues we been having with our 3 yr old 4052M tractor since the fall of 2018 (it was 2 yrs old and just out of warranty)

To catch you up since our last posting, weíve made Two trips back to dealer and they made one trip to our home our to work on our 4052M and after going over it throughly, as of now it is still showing a STOP signal and shutting down after using it for 20 minutes.

Two weeks ago we took it in for the STOP signal issue itís been having and they told us that there was algae in the gas tank and we were storing our gas wrong and to store the gas can on wood. The drain hose was not draining so they cleaned it out. They installed a new fuel filter and checked codes. Everything else checked out ok. $400 this time. We Used tractor to get work done and again 20 min later the STOP came on and tractor shut down. Later it started and we took it back to JD. This time they told us they had to replace the suction control valve. (told us it was under warranty) Got it home and it wouldnít start. They came to us to work on it and said the new sc valve wasnít on tight enough or somehow jiggled loose he tightened it and it started. No codes came up. Then we Used it to get work done and the STOP came on again 20 min later now itís back in shop AGAIN! You mentioned (a few weeks ago) it could possibly be an electrical issue in the gage sender circuit.

After having everything you mentioned checked (on the earlier thread a few weeks ago) do you think that might still be our issue? Weíre talking with them on Monday and are open to any suggestions you all might give us for them to check. Thank you for your time!

Re: 4052M keeps showing STOP signal

I looked back through the codes you posted the first time and one of them (it is missing one digit) says the fuel pressure limiter is open. I am guessing that is why they installed a new suction control valve since that is what controls fuel pressure. If a new suction control valve didn't cure it, The pressure limiter on the fuel rail may need to be replaced or you may simply have a pinched or restricted fuel return hose. I had one of those one time. Have them inspect the return line all the way back to the tank to be sure it is not restricted. This is assuming you are having a 523468.09 or 523469.00 or 523470.00 code. If not this problem, please post the current error codes. There is a special procedure the dealer must do to clear some of these codes to make tractor run properly after repair of some of these codes. Tell them to check out how to clear "latched" codes.

Re: 4052M keeps showing STOP signal

To jd110
Some more history to share after meeting with my dealership folks. My husband is not very good at paperwork so I requested all repair tickets. On 10/31/17 when the tractor was one year old and 127 hrs on it, it was shutting down with STOP signal and throwing code 000157.03 and had to have the suction control valve and pressure limiter replaced. I posted the service invoice on Tapatalk from the next issue on 9/25/18 from the codes shown you told us the fuel pressure limiter was open and the fuel rail may need replaced or the fuel hose may be pinched...if you look at the service invoice you will see they determined the problem to be a loose ECU connector Pin 26 signal wire to the fuel pressure sensor. However, we continued having the same shut down problems as the 1st year. On 10/30/19 we took it back in and this time they did the following (Iíll send a picture of the service invoice)
They told us that the fuel was bad and had a black thick film in it. I spoke with mechanic yesterday and he thought that was one of our problems this time. I showed them your comments about the fuel pressure limiter being open and a possible fuel rail problem and to check the codes and clear the latched codes...All I know is they had to overnight two parts and the sales rep couldnít remember the names of the parts...Long story short, Iím not sure they ever fixed the root of our problem (the cause of the suction control valve going bad) that began in 2017. Iíll keep you posted on what they come up with to be the problem this time...ĒsighĒ

A new update just in...the dealer just replaced the pressure limiter today. On Oct 9th they replaced the suction control valve. This brings us to a full circle from back in 2017 when our troubles first started and they had to replace the suction control valve and and the pressure limiter valve. Iím wondering why you might think that 2yrs later they had to fix the same problems. What could possibly cause them to go out after only 2 years? Thank you for any advise you might have to offer! Would you trade for a new tractor if you were us?

Re: 4052M keeps showing STOP signal

Hard to say what caused the failure again. Hopefully they checked for pinched fuel return lines. With the new fuel systems that are designed to meet emissions, good quality, clean fuel is a must. The fuel pressures are so high that any impurities in the fuel wreaks havoc. You may want to send out a fuel sample to be sure your fuel supply is good. The suction control valve and pressure limiter have not really been problem areas at our dealership for the compact tractors. I am only remembering one set we replaced in the past several years and it was due to a pinched return hose. It is recommended they get replaced together. I don't see where they recorded any error codes this time around, but they did perform a service regen on your diesel particulate filter(DPF) but that should not cause problem with the fuel system but it could have given you the STOP signal. It is important to allow the normal regens to complete when they start so that the DPF doesn't get clogged. Unfortunately all of the emissions systems can cause a lot of grief. I personally don't think you should trade, but that is something you need to decide for yourself. If you are losing confidence in your dealer, you could try to take it somewhere else. With the complexity of the newer equipment, the dealers need to invest in training for their techs to stay up to date with the technology.

Re: 4052M keeps showing STOP signal

I read that the electric fuel pump failure could cause the suction control valve to go out. Have you ever experienced that? Thank you for working through all of this with us. You are one of the good guys to take your time and answer our questions.

Re: 4052M keeps showing STOP signal

I have not experienced a suction control valve failure due to a bad electric pump. I have seen suction control valves replaced when there is nothing wrong with them. This is usually when you have low fuel rail pressure codes. Your codes indicate rail pressures too high that causes pressure limiter problems.
