Plenty of options here in the UK if you google the Pt No, don't know about Spanish availability that would be down to you. Could see if there are any breakers as it looks like it is fitted to vehicles other than LR. If the reading changes when you disconnect the sensor that is a good sign that the ECU and wiring would seen to be ok. Don't know if they are a common failure item, if they are and you go to a breaker it may be worth taking your vehicle and Nano to try it at the breakers to be sure you get a good one.
