XUV 620i Error code 24?

[Skipholiday]

My XUV has been in the shop for over a week now.
The problem was that it would lose power while under load.
If we attempted to go fast or climb a small incline she would bog down.

Gas is good, new fuel filter and problem is still present.

When it is 1st cranked it runs perfect. I can go across the yard fine.
If I attempt to accelerate she bogs down like there is no gas.
Turn it off and restart and it runs perfect again.

The JD mechanic ran the test on it and it came back with code 24. (speed sensor). They replaced it and still the same problem. We traced all the wiring for the sensor and it looks perfect. So we replaced the computer and we still have the problem..


Any suggestions would be appreciated.

get a carberator.lol na just jokin. how much power you losin. i would say it's a oxygen sensor maybe. that's one reason i stay way from them eletronics i much rather my carberator. is there a rev limiter on there any place??

 

[Skipholiday]

I'm not sure if they have a rev limiter. The speed sensor is by the rear axle.

Hmmm oxygen sensor could be worth trying.

Seems JD doesn't want to try some stuff without a d-tac. (whatever that is)

is it the engine itself that is bogging down ?it does it while you rev it up in neutral?or does it run fine while your pumping the pedal while sitting in naetral? i know when i run in the mud alot and i do i get some mud inside of my brake pads and when i run down the road it gives me a binding feeling like when i would be pulling a load but i ain't. so what i do is go home pressure wash the pads out really good and then hit them with wd40 . don't worry the brakes still work after.lol but the bogging down feeling is gone till after you go mudding again and the mud gets clogged again. but that d-tac thing i don't know what that is.they wouldn't tell you what it was?

Its the engine. Sounds exactley like it runs out of fuel.
Turn the switch off and back on and it runs perfect again..

Injectors ? Dizzy ?

how's the fuel filter.sounds like the problem them rhinos have with the dirty tanks huh.i had A nissan pickup that would do that and it was a shorted out wire going to the fuel pump.the way i solved that problem was i ran a wire directly to it and then to a switch in the ignition that came on with the key on. and it never gave me a problem again. do you check the voltage going to the fuel pump when this is happening? it could be cutting off.

 

[Skipholiday]

Fuel filter waas the 1st thing I changed.Then the fuel.

you didn't do any chip modifying did you(it's still the stock chip in it right)? did they check the computer board to see if it has a short in it?

Fuel Pump? I heard of a tractor doing this once, and it had a rag in the tank. JC

I think he said they put in a new computer too.

 

[Skipholiday]

New computer and speed sensor.
I've had such good luck with the xuv, now the old girl has let me down..

had a fuel pump going out in a suburban that acted like that. sure was a pia until we figured it out. of course the fuel pump was inside the tank.

thats why i rather a good old carberator . that efi is nice but when that eletronics go out the whole engines goes down. so is she running again?

 

[Skipholiday]

They are going to put a new throttle body on now. Seems like they are guessing..

I thought about a fuel pump as well. The confusing part is that when it acts up, you can cycle the power and it runs good again...

does cycling the power reset an electrical breaker? fuel pump would blow out a fuse that killed the lights and engine.replace the fuse and everthings ok for a while. the ok time kept getting shorter.

if it was at your house you could have run a wire straight to your fuel pump and bypassed the whole stitch.that would have told you if it was in the eletronics part.plus you would have known how to setup a backup system for when it goes out agian.anyway you can get a schematics of the xuv?

 

[Skipholiday]

LOL you trying to be funny Tommy?
JKIN bro. Its funny you ask tho. I was speaking with a JD service tech and was suppose to be sent a schematic.
They sent me a diagram on how to replace fuses and use a booster battery.

no that's what i did for my old truck.lol but it being on warranty let them fix it .

 

[Skipholiday]

Problem fixed. Found out it was a code 11 instead of a code 24.
Code 11 is throttle body. Replaced the throttle body and all is well.
