Hello, I have a read the codes of my peugeot 307 and i got P0406. This indicates Exhaust Gas Recirculation Sensor 'A' Circuit High.

Hello, I have a read the codes of my peugeot 307 and i got P0406. This indicates Exhaust Gas Recirculation Sensor 'A' Circuit High. I reset the code, but it reads as code pending on the software and then the engine fault returns after a short while. I got a mechanic to have a look. He cleaned the egr valve and said it was really dirty. He doesn't know what to do next and I really want to solve the problem. Does anyone have any advice as to a affordable mechanic who will be able to find and fix the problem? The engine was losing power at times but I haven't noticed this happen since he cleaned the valve.

The car in a Peugeot 307 1.6hdi 2005 with a dv6ted4 and 96k miles. I want to sell this car asap and would like to fix all faults before selling.

I live in Dun Laoghaire and I am willing to travel to find a good but affordable mechanic.

The Suspect areas for the egr P0406 fault are..
1)Engine ECU 5V shared supply
2)Electrical harness
3)Connector
4)EGR electrovalve

Check wiring,connector for damage...after that if you got you hands on s/h egr valve pop it in and see if that helps...:)

There are a few Dublin based mechanics on here who should be able to sort
you out...:)

Thank you I really appreciate the advice. Since I last reset the faults other codes have appeared that were present before as well:

p0489
P1461

I have been talking to a mechanic in clondalkin and he wants to do a diagnostic for €30. i am afraid all he will do is tell me the same codes. Atlas quoted €45 and peugeot €75. I really want to get it fixed asap as I need the cash but I am afraid no one will buy it with the fault. Do you know decent mechanic in Dublin?

It seems likely that the EGR valve itself is faulty. Proper diagnosis, i.e actually testing the EGR valve rather then just reading the fault codes is what's needed but I've seen a couple of EGR's go on these engines.

Thanks again to Row, drove down to him last night and he had it whistling like a canary in no time. I'm so glad there are some trustworthy people left to save me from spending half the cars value trying to get her running.
And also thank you Nissan Doctor for the advice, really appreciated.

It was nice to meet you and hopefully you've gained some info..:cool:

For others...I fitted/Coded in a good S/H egr valve and it sorted the problem.
The old one looked fine but the motor side if it has sort circuited and was bringing up a continues egr related fault codes.

Hey guys, sorry to dig a thread up.

I'm having the same issue now - what was the resolve for this one? Was a replacement egr required?

Best way forward is a diagnostic scan for fault codes. These messages can appear for a variety of reasons. PM for details of diagnostic services in your area if you're stuck.
