Peugeot iOn Temperature Sensor Issues

I'm having an issue with my 2019 Peugeot iOn, an electric vehicle, at 176663 km. I'm getting an error related to the outside temperature sensor. Because of this, the air conditioning won't switch on, the spray nozzles are frozen even when it's not that cold, and the mirror heating doesn't work. It's likely a cable or plug connection issue with the sensor itself. Has anyone else experienced similar gremlins? A workshop estimated 95€, but I'm hoping to get some insights before I go that route.

A 2019 Peugeot iOn is experiencing issues with the outside temperature sensor, affecting the air conditioning, spray nozzles, and mirror heating. The problem is suspected to be related to a cable or plug connection issue with the sensor. A similar case involved a corroded connector near the front bumper, which required professional repair. It is suggested to have a workshop inspect and potentially replace the connector to resolve the issue.

Did this summary help you solve your problem?

Whoa, that sounds familiar! I have an iOn too, and I had almost the exact same cluster of symptoms a while back: AC dead, weird temp readings, and the heated mirrors were acting up too. I didn't get the frozen nozzles, but I suspect it's the same root cause. Did you check the wiring harness near the front bumper? That's where the outside temp sensor usually lives.

Thanks for the quick reply! Wiring harness near the front bumper, you say? Any specific area I should be looking at? And what exactly was the fix for you? Was it just a loose connection, or did you have to replace the sensor?

Yeah, it's a bit exposed down there. I didn't actually fix it myself, to be honest. I poked around a bit, but in the end, I took it to a workshop. They said it was a corroded connector and replaced the plug. Cost was similar to what you've been quoted. Given your symptoms, it does sound like the same thing. I'd get it checked by a professional, especially if you're not comfortable messing with the wiring.

Appreciate the confirmation. Sounds like a trip to the workshop is inevitable. I'll let them know to focus on the connector and wiring harness. Thanks again for sharing your experience!
