It just tells me there is a fault. I have not had a scan done but the VAG system scan tells you exactly what sensor(s) is/are faulty.

I have a similar fault on the Fabia and my research shows that 99% of the time it is a faulty sensor. I was advised to buy a sensor and swap them out one at a time to see which one is faulty.

Update: a car expert YouTuber has confirmed this advice. He stated that if one of them doesn't work, the system is disabled. I must say that I am pretty disappointed. I'm a new Honda owner of 2 weeks, and having this issue has quite frankly p**sed me off . I've seen videos where you can tell if a sensor is working by touching each one while the system is supposed to be working, it kind of clicks/vibrates, so I'll be trying to figure out which one has stopped working tomorrow.

I did suggest you may be able to test each sensor in post #7.

If you've only had the car for two weeks though, I would suggest the car dealer should be sorting it out.

Thank you mate. The car dealer is a couple hours drive away, and they would probably need the car at least a few days, which makes life too difficult. They did offer to take a look.

I just hope I'll be able to tell which sensor is dud.

although I agree the car dealer should be sorting it out I can understand this is not always convenient. 
Can you not identify the problem sensor  somewhere quiet by physically  driving/reversing into actual  obstructions such as traffic cones.   It should be easy enough to identify if one sensor  activates for a cone  and another does not .   If there is no obvious difference it may indicate more than one sensor is faulty  or the system as a whole has a problem, or not switched on .

If you can identify one  faulty sensor  then at least you know where you stand for getting it repaired under warranty.   If you can positively  identify a particular fault to the dealer  its on record that its  within the warranty period  and he might agree to you getting it fixed at his expense  by a specialist  more local to you.

I dont know how  easy the sensors are to change. If you are a keen diy mechanic  with no warranty  you could even consider swopping sensors between left and right to see if the fault migrates with the sensor.  You will then know with more certainty a new sensor is required. But if they are reasonably cheap buy one anyway as Jocko suggests.

A diagnostic check on the vehicle will identify which sensor is at fault. Each sensor creates a different trouble code, as well as other trouble codes relating to the interconnection of the sensors and units.

Try blowing air into each sensor or use vacuum cleaner on each .Final check a smart smack against each one.

It could be something as simple as an over enthusiastic pre sale preparation clogging it with polish.

The whole system is disabled, which is something that happens even if it's just the one sensor that's not working.

I am having a bit of trouble finding a sensor that is compatible with a 2016 Jazz, they aren't really available so I might have to source one through Honda.

I tried the rubbing your finger over each one AND recording them with a camera to hear a click, and none of them are working which could mean any number of things.

I am considering buying a diagnostic tool but I need to do slot of research before getting one.

I can neither hear nor feel any of mine clicking. One guy on the Skoda forum bought one of those engineers' stethoscopes and said even with that he couldn't hear a working set clicking. I think for the majority of cars, being able to hear them is a fallacy. The way to check it is with a suitable diagnostic set-up (too expensive for an average owner) that pinpoints the defective sensor.

I have been considering getting my own diagnostic tool or getting it done professionally, but I'm tight with money and am having trouble justifying possibly spending over £50 on a parking sensor when I could manage without, and after spending so much buying the damn thing... I really was hoping it was a quick fix

As the WD-40 trick didn't work, I'll definitely give this a go too

I am of the same opinion. I have never had parking sensors so the fact mine don't work is neither here nor there. I use my bumpers as parking sensors!

If the sensors are just covered with something, the system doesn't show any warnings. It just switches off. With an orange "i" on the display and a blinking green light on the switch it seems obvious, that there is something deeper.

I agree that an auto electrician with a suitable diagnostics tool is the quickiest, cheapest and best solution. But if that is not possible, then I would start by checking all sensor wiring connectors as well as the switch connector.

I doubt that any generic diagnostic tool is able to reveal anything about these sensors. You need Honda specific one, which are priced for professionals.

I think you may be right, but I know it won't be cheap.

I think I will have to phone a few places to gauge how much diagnosis will cost.

It's such a shame and very disappointing that the system gives no indication about what it could be that's causing the problem.
