Jumper interior temperature sensor issue

Hi, I'm having issues with my 2007 Citroen Jumper, it's the diesel engine. The automatic temperature control has completely stopped working. The air conditioning system doesn't even switch on anymore, and a code reader shows an error related to the interior temperature sensor. Is it a dodgy sensor, or a broken wire? Any ideas where to start?

Sounds like a classic faulty interior temperature sensor issue. The symptoms you're describing are spot on. Have you checked the cable and plug connection to the sensor itself? It's often a simple fix like a loose connection or corroded pins. Think of it like a faulty light switch – sometimes it's the bulb, but often it's just a loose wire.

Thanks for the quick reply! Where exactly am I looking when you say check the cable and plug? Is there a common location in the Jumper where these sensors usually reside? I'm not mechanically minded, so any specifics would be super helpful.

Alright, the interior temperature sensor on the Jumper is usually located somewhere around the dashboard, often near the steering column or sometimes integrated into the climate control unit itself. Since you're not too familiar with auto electrics and you see a stored error, I would suggest visiting a workshop. It's like trying to diagnose a heart murmur with a stethoscope you barely know how to use; you might hear something, but you won't know what it means. A professional check will save you time and prevent further electrical problems.

Thanks, that's really helpful advice. I'll take your advice and get it booked into a workshop. Seems like the best approach to avoid making things worse. As you suggested, the issue was in fact the interior temp sensor, or more specifically, a broken wire leading to it. Total bill was 95€ including the check. Thanks again for the insight!
