Mine did that

Return spring on foot throttle

But the foot pedal seems to be functioning ok in cab ,? Or do I need to look elsewhere

Have u held the diff lock button until the beep comes on

 

[Cowabunga]

Have a look behind the foot throttle where there is a linkage to the potentiometer and to the hand throttle cable. Is something either jammed or come loose down there behind the shield? That is all the physical gubbins you will find in the cab for throttle control… the hand throttle, its cable which loops down to the foot pedal and its potentiometer. Otherwise it is all electronic.

 

[Buffalo Jim]

Linkage wise etc all looks good ,
Put a new sensor in ,
I have tried to calibrate and the wee cog symbol comes up but I get no beep ,
Laptop time I think

 

[dee]

Don't worry about the beep as long as it's showing the cog
Are you pressing the diff lock switch at idling and then the full revs to calibrate the throttle

 

[Buffalo Jim]

All sorted thankfully , bad earth on the bulk head caused everything ,

 

[Buffalo Jim]

Whilst in the topic anyone know what that error t203 is ?

 

[dee]

T203 is for short circuit on fwd solenoid.
Is the tractor driving

Yeah tractor driving perfect no issues atal now just brings up that fault every now and again

 

[dee]

Intermittent faults are always the worst.

Yep , must take a look round fwd solenoid clean up connection and earths etc and see I guess
