2016 L4701 E-84 sensor

[TMusik]

I've had recent acceleration problems and not trying above 2000 rpm. I replaced fuel filters and used both Seafoam and MMO alternately to clean injectors. Problem persisted. I was going to remove injectors for better cleaning, but before I could get to it I got code E-84 and tractor will not rev above idle with hand throttle or foot pedal. When looking up TPS sensors for this tractor I found Speed sensor #1J985-65830. Is this the proper sensor for the repair? I found it for $24 and am ready to buy it but want a second opinion. Still waiting for my Kubota dealership to call me back to see if it's covered on power train warranty, but I can replace it myself quicker than taking it to them.
Y'all's help and advice is greatly appreciated.Thank you.

Yes, thank you. I've already read that thread. It's helped a good bit. But I need to know product specific information. Just talked to Kubota service department again. They're waiting to hear back from Kubota on if this is covered under warranty, but he also had part # 1J800-59710 and was checking with his service tech on what is the correct fix. Said it could be a week before we hear back from Kubota on if they'll honor warranty. So if I had the correct part in hand I could fix it quick and get back to it.

It might be covered under the emissions warranty if within time period.

Example document: DOCUMENT Page 11 and 12 give high level parts coverage.

you can replace it but then you have to adjust it properly. You got the information to do that?

As a side note, I would really advise you to stop adding all the snake oil products to your fuel, as when you clog up the DPF filter it won't be covered by warranty.

Try this after the new sensor install.

Seems like you might be ahead of the game if you were to haul the tractor to the dealer and let him run the diagnostics on Diagmaster. If you start pulling injectors on that model you are likely to make matters worse. And void your warranty. Resetting the ecm after you install the sensor may not be all that easy. The directions in shop manual are not all that straight forward. You do have the shop manual?

if you pull injectors for cleaning be prepared to replace them. I don't remember the actual cost but I think they're about $1000 each.

and if you do have to replace them you won't be able to properly do it without registering the new injectors to the ecu

and if you have the old ones sent out for testing you better know which ones came out of which hole they are all 4 different from each other even though they all carry the same part number from kubota. Oh what fun

lots of guys have gotten away with it for a little bit and then the dpf gets plugged or it wants to regen way too frequently and they blame it on that dad burn dpf, when in fact it was the injectors information not being entered at all or improperly, causes all sorts of potential issues. I can remember at least one for sure, SVL90, guy put 4 new injunktors in it and complained all day long about how poorly it was running, something was wrong with the injectors, etc etc. So I appeased him and removed all 4 injectors (no fun task on an SVL90), got the information off of them, checked the information in the ecu and guess what? Different. Explained it to the guy, who then agreed to pay the labor costs to re-register them individually and after that it was hunky dorey. Only cost him a set of injectors (that he purchased) and a bunch of labor for me to pull them out, then reinstall them. Would have been about 1/2 to just let us install them the first time but dealers are all out to get people, they call us stealers but ain't got a half a clue what actually happens behind those doors.

consider injector removal and/or replacement dealer only level stuff

you may have some emissions warranty left on it let them deal with it. If you are not sure about emissions warranty call dealer with your serial number and ask 'em about it. Emissions only covers some items that deal directly with emissions stuff so it may not be fully covered, BUT, if you have to carry it to the dealer tell them to call you if it's an item that is NOT covered, make them put it on the repair order and then sign it.

$4000 worth of injectors gets expensive quick. Then if the supply pump is damaged, add another $2500 or so. Fuel rail? $1500 give or take. Don't take long to add up to a bunch of money. Let kubota buy the stuff if it's needed, if they can. Little stuff I do myself but if it's gonna be a bigger deal, pay someone else or let the manufacturer eat it if at all possible.
