Problerma with tps caravan 96 engine 3.0

Good afternoon I have problems with a carav 96 which, when accelerating or does not react, it does not give me fault codes and the pump pressure is correct.
Al Disconcat the TPS works correctly. They could guide me how this sensor is stressed manually.
Millions of thanks to hand

TPS is a gradual resistance. As you accelerate this, it goes through a conductive material that to different displacements of the footprint. Remove resistance by sending a specific voltage to the computer, solution: some can be opened. First, nothing to recalibrate the needle. make sure to make good contact with the conductive material. And failing that the track is without damage or much wear ... and if there should be repainted with graphite resistive paint ... I hope it helps you something!

It is correct what Umekcito says but I have an eye on the caravan on occasion it is better to make the expense and buy the spare, in any case the failure that you also have the proboca the flow.
