John deere error code Ecu 1180.00

[Cotfarm]

hi I have a Jd 6930 with faulty error code ecu 1180.00
Only come on at 80' on the temp coolant is at max thermostats changed turbo looks ok
Any body got any ideas
thanks in advance

From memory this mind, I think it maybe inlet air temperature sensor, it's the one on the pipe from the air filter to the turbo.

I have the same. Can't run over 25lts/hr. It's exhaust temp. I know my turbo is finished and it is probably that to blame

 

[green giant]

I don't think exhaust temp is that code, but I may be wrong and stand corrected.

Yes, be interesting to see now. Why would it tell you to slow down for inlet air temp?

I'll check in the morning

No egt sensor on a 30 series. There are two charge air temp sensors used to manage egr and so check coolant level and if there is a restriction to coolant flow for the charge cooler.

I have changed the intake sensor and the one in the inlet manifold
Still no better

1180 is turbo pretty sure

 

[Db880]

1180 is usually a turbo. However I have also seen low coolant cause this as the turbo actuator isn't getting cooled. Check the coolant level. With engine running and header tank cap off. Put heater on when filling to help remove air locks. Make sure she is full of coolant. Like full! It will blow out what it doesn't want!!

 

[Cotfarm]

Bit more testing and playing around all sensor changed
Egr temp re-pluged back in ( been mapped out )
Ecu readings
70..-..60 was 140 before reconnected
71 ..-..35
72..-..22
73..-..22
Can't work out why the intake and the charge air cooler temp are the same ???

Probably the turbo- check for header tank oring leaks tho.

 

[Cotfarm]

Just done header tank o'rings, maybe the last owner left it to long and I
Think due to them failing its burnt out the actuator
I could be wrong and didn't want to fit a new turbo @ £1500 but it's looking that way

Does the turbo feel smooth or jerky?

 

[Cotfarm]

Turbo feels smooth,..... may be a little light from the actuator

 

[Mursal]

As its a variable vane turbo, can you manually work the turbo linkage/control rod to free it out, or at least check for smooth movement?

 

[NZ Tech]

its not really a seizing issue id say- they usually feel ok. The linkage wears inside the turbo exhaust housing increasing slope in the arm to vanes. I dont know if building the arm back up would help but its worth a shot. Tig hard face and smooth back.

Still looking for cheaper turbos but
While we're on
Anybody know how to make the 40k auto power do 50k
It's Got after market air breaks
Is just some codes or is there more too it

I've got my new turbo booked for next week. Gone genuine.
Had a real problem with the 3420 handler last month and I think if it wasn't standard the dealer might have just walked and left me on my own with it !!!
