Terrano Tire Pressure Sensor Fault

Sounds like it could be the sensor. Are you getting the error on all tires or just one? If it's just one, that would point to a specific sensor issue. These sensors do have batteries, and after that many kilometers, it's quite possible one (or more) might be on its way out. Have you tried resetting the error to see if it comes back immediately, or does it take some time?

Thanks for the quick reply! It seems to be intermittent. Sometimes the light is on right away when I start the car, and other times it takes a few kilometers before the error pops up. And no, it's not showing a specific tire, just a general low pressure warning. If it is the battery, is that something I can replace myself, or is it better left to a professional?

Okay, the intermittent and non-specific warning does lean towards a sensor issue, and probably battery related given the age. Replacing the sensor battery can be done, but honestly, it's usually more trouble than it's worth. The sensors are often sealed units, and you risk damaging them trying to get them open. Plus, you'd need to reprogram the new sensor to the car's computer. My advice? Bite the bullet and take it to a workshop. They can diagnose it properly and replace the faulty sensor. It will save you the headache.

Thanks a lot for the advice! I suspected as much. I took it to my local shop, and they confirmed it was a sensor with a dead battery. They replaced it and reprogrammed it, and the error is gone. Cost me around 280€, but at least it's sorted. Appreciate the help!
