'06 110 TLB - Ground Speed Sensor Fault

[WTRanch]

First post but I've had my 110 for 6 years... love it and it runs like a champ (deere). Recently I have been getting a fault code after the machine has warmed up and run a bit. I checked the connector next to the rear transfer case and it's not disconnected. It's a bit tight to get into that spot with both hands so I haven't pulled the connector apart to remove any oxidation from the contacts. The wiring on both sides of the connector looks good... not chewed up by packrats.

Anyone have any ideas of what may be causing this and how to correct?

Does anyone know if the sensor fault will affect driving speed as it mentions is possible in the manual?

My 110 does exactly same. After a bit of warming I get three short flashes followed by one long one. It has done this for several years. I have not noticed any deficiency in performance so I never did anything to correct it.

It did on mine… it got to where I could only move by creeper switch.

$50 and fixed.

@threepiece: I don't want to ignore it... I know that when I'm in the worst possible spot and need it to run properly that it will cause an issue.

@ultrarunner: other than being a pretty tight spot to get both hands and tools into it appears to be a pretty straight forward repair. Am I correct, 1 bolt holding on the sensor to the transfer case and disconnece/reconnect the wire harness plug?

For mine exactly as you describe... one wire I believe

Thank you for confirmation. I'll order the part tomorrow.

The last one I bought at Deere cost $79

I had the jobber discount when I bought at $57 for the first one.

Following up with some detail in the event that anyone is searching the forum for information on fixing this issue.

The Deere parts folks at 2 different dealers both came up with part # LVA11935. I placed and order for this before I saw the reply above from @ultrarunner who used LVA17409.

I'm a 2 hour drive to the closest town/Deere dealer so when I went to pick up the part they said they would have to order LVA17409 and by the time I pay for fuel for another round trip (and risk LVA17409 not fitting properly requiring a 3rd trip) I decided to just get what was specified and pay the higher price, $137.

Upon removal of the sensor, I see that the part number is printed on the cable and it indeed was LVA11935. Note to have an oil drain pan placed below as you remove the sensor as about 3-4 ozs of hydraulic fluid will drain out.

In my case I was unable to pull the sensor fully out of the housing because the hydraulic lines were just barely interfering. Loosening the top bolts to the filter housing and the hose clamp forward of the filters allowed enough play in the lines to remove and replace the sensor. All in all it was about a 20 minute job with half of that time required to mess with the hydraulic line clearance.

Thanks to @ultrarunner for his information. His part was $50 cheaper and may have worked fine. I asked the guy at the parts counter at 4Rivers Deere and he was unable to cross-reference the 2 parts to determine suitability. So if you're tackling this repair check the cable leading into the sensor for a part number. Ultrarunner reported that the cheaper part number worked just fine.
