Peugeot Boxer water sensor malfunction
Summary of the thread
A 2018 Peugeot Boxer is experiencing a check engine light and rough running, with an error code indicating a water sensor malfunction. The initial suspicion is a faulty moisture sensor or issues with the cable or plug connection. After checking the wiring, which appears intact, the suggestion is to either check the connections for continuity or replace the sensor, as the error code specifically points to the water sensor. The recommendation is to schedule a professional inspection to potentially replace the sensor, aiming for a straightforward resolution.

Wiring looks ok. Could be internal corrosion, I suppose. The error code nails it to the water sensor. Would you suggest replacing the moisture sensor completely, or is there any point checking those connections for continuity?

If the code's specific and you've checked the easy stuff, I'd lean towards a faulty sensor or wiring. Checking continuity is a good idea if you have the tools. But honestly, chasing electrical gremlins can be a nightmare. With these symptoms I would suggest you should schedule an appointment, as it could be something simple like replacing the sensor, for around 95€.

Cheers for the advice! Sounds like I've poked around enough for one weekend. Booking it in, and hopefully, it's just a sensor swap. Fingers crossed it's a quick fix! Appreciate the help!

Water sensor issue on a Boxer, eh? Rough running and check engine light, classic signs. Have you checked the sensor's wiring harness and plug for any obvious damage – corrosion, loose connections, that kind of thing? Is the error code pointing specifically to the sensor, or is it a general 'engine management' fault?
