Peugeot 307 Rear Parking Sensors - Advice Appreciated

[Skirmisheer]

I recently bought a 2007 1.6 Petrol 307 SW SE and have been sorting various issues that the car came with.

The latest project is trying to make the rear parking sensors work. When I put the car in reverse I get a message on the screen to say that there is a fault with the parking system and a short beep. The reversing light is on. I've just removed all sensors and cleaned them and WD40'd the connections to try and remove any moisture but the problem is still there.

I'd therefore appreciate any advice/information that may fix the problem as it is nice to have rear parking sensors working.

Thanks
David

Use the mirrors.

or

Check the sensors are getting a feed etc.

[Skirmisheer]

What great advice...

Funnily enough I do use the mirrors but sometimes there may be something small just out of sight and that's when parking sensors are very useful.

Perhaps someone else can offer some technical advice that is rather more useful.

Im not certain how they work but i imagine they will get the feed off the reverse light switch on the gearbox same as the light will. If the light is working check to see if they have a feed also.

it may just be as simple as a failed sensor, try putting the car in reverse with the engine off and feeling each sensor face with your finger tip, You should feel a slight pulsing.
Failing that it will probably need a diagnostics carrying out, there is usually a small control unit somwhere for them too.

You may have one or more duff sensors. With the ignition on, put the car in reverse and listen VERY closely to each sensor in turn. You'll need to be somewhere very quiet and if they're working, you'll hear a faint, rapid ticking noise. You may be able to identify a duff sensor and check its wiring (I had a one on my old beemer squashed between the bumper and the body). You can usually change them individually, or if you're lucky like I was, repair the wire and yippee a working system!
If you hear no ticking pulses from any of the sensors, it's most likely to be an issue with the control box.

Best of luck.

Thanks for the replies.

I've noticed that the warnning message only appears on the display when the engine is actually running. Moving the ignition to position 2 doesn't make the message appear. Are the sensors likely to work without the engine running? Obviously I need a very trustworthy person in control of the gears and clutch if I'm to listen to the rear sensors while the engine is running!

While I can imagine the actual sensors failing due to various reasons I would have thought it highly unlikely that the control unit would be faulty?

Why?, after all it's a French car ...

You'll be bloody lucky to hear the clicking sounds over the engine running!

I know that I'm late in replying to your problem, but I've only just joined the forum. To correct this problem, you really need to take the car to a Peugeot agent, or if you know someone with an analyser, then they could help you by reading the fault code, and then rectify the problem, and delete the fault code. If the fault code is not deleted from the ECU, then you will continue to get the fault code, even if you rectify the fault.

Its a Peugeot 307 its a wonder anything electrical works on it at all, even for Peugeot the 307 hit a new all time low.

[Skirmisheer]

The fix was easy in the end. I found a very useful website that gave instructions for testing the sensors using a multimeter and measuring the resistance. The faulty sensor was found and another purchased off ebay. One connected up the whole system was and still is working fine. The sensor fault had nothing to do with Peugeot as most cars use exactly the same type.
The rest of the electrics have been fine on the car too so I've got no complaints about the 307.

Which website has the information on how to check the sensors with a multimeter. I supect I have a faulty sensor.

[Skirmisheer]

Here you are.

I wasnt getting at you but you really are lucky not too have electrical problems with a 307. Peugeot quality went downhill badly with the 07 series cars but I think the 307 was an all time low, apparently water leaks somewhere around the n/s windscreen bottom corner drip onto a circuit board somewhere under the dash which controls most of the vehicles operating systems.

You may well be right however while I had mine everything worked fine. I now have a 2.3 Mondeo estate but the only reason I changed was because I needed an automatic because of my dodgy knee. I'd have quite happily had another 307 SW but the performance with auto boxes is pretty poor.
