Crossroad fog sensor malfunction

Hi, I've got a 2007 Honda Crossroad with a gasoline engine and a strange issue. The fog sensor seems to be malfunctioning. I'm getting an error stored in the memory, the air conditioning won't switch on, the spray nozzles are frozen even when it's not that cold, and the mirror heating isn't working. I've checked the fuses, but they all seem fine. Any ideas?

A 2007 Honda Crossroad owner experienced a malfunctioning fog sensor, leading to issues with the air conditioning, spray nozzles, and mirror heating. The problem was identified as a generic 'fog sensor malfunction' error code. It was suggested that a defective cable or plug connection could be the cause, affecting multiple systems. The issue was resolved by cleaning and replacing a corroded connector on the sensor harness, restoring all functions.

Sounds like a dodgy sensor alright. When you say 'error stored in the memory,' are you referring to a specific error code thrown up by an OBD2 scanner? Could be a CAN bus issue if multiple systems are affected, which is plausible given the symptoms.

Yeah, sorry, should have mentioned that. The OBD2 scanner is throwing a generic 'fog sensor malfunction' code. Could a defective cable or plug connection really cause all these problems at once?

Absolutely, especially on a car that age. A bad connection can wreak havoc across multiple systems that rely on that sensor's input, especially if they're daisy-chained or share a common ground. Given the cost of a new sensor, I'd check the wiring and connections first. If that doesn't fix it, I'd recommend getting it checked by a workshop. Sounds like you're on the right track though.

Thanks for the advice! You were spot on. Took it to a workshop, and it turned out to be a corroded connector on the sensor harness. They cleaned it up and replaced a small section of the wiring. Cost me 95€ all in, and everything's working perfectly again.
