I have a new tm320 loader and have second time a p204F-9A

Customer Question

I have a new tm320 loader and have for the second time a p204F-9A code on the tractor. The last time the service person changed the DEF pump and it worked. The service person can not get to me for a week and we would like to use the tractor. The tractor is derated and cannot hardly be moved. Is there a way to reset the tractor so it can be used? The tractor has about 100 hrs.

Hi there,

This error is related to the DEF fluid.

Check that you have enough fluid in the tank.

If you do have enough fluid, then the tank sensor may be faulty, or it may be caused by a loose/damaged cable from the sensor.

As the tractor is new and only has 100 hours on it you should insist that the service person gets to you much more quickly - I would demand a visit within 24 hours, or suitable compensation if they cannot reach you within that time.
