The connector on the end is the sensor (to the left on the picture above).
Here is the sensor on its own that Citroen do not sell:

No, you misunderstood. I meant the connector , with the cables behind.

Re: Citroen C5 2009 EGR valve
The connectors to the sensors will be part of the engine harness:
This is the main engine harness: 6569TQ is the part for the harness (1)

Re: Citroen C5 2009 EGR valve
Now I purchased used fuel pressure sensor. But unfortunately I cut the old one from the harness long time ago. This new one have different colours on the cables. How do I connect it right?

Re: Citroen C5 2009 EGR valve
Hi Sufii.
Ok, so the colours are not important as PSA used anything going! What's important are the pin outs.
Wire pin outs:
Pin 1: 6774 (Line Pressure Signal) This goes to pin G3 in the engine ECU
Pin 2: 6773 (Line Pressure - Supply) This goes to pin C4 in the engine ECU
Pin 3: 6772 (Line Pressure + Supply) This goes to pin B4 in the engine ECU
The Engine ECU connection should be a brown 48 pin connector.

Re: Citroen C5 2009 EGR valve
Thanks for very good help. But I have to admit that my car is still standing still. Been a few months now. So I replaced the EGR valve and the fuell pressure sensor regarding to the chart diagram you posted. But the car still won't start. What can I do further?
Thanks for good help folks!

Re: Citroen C5 2009 EGR valve
Are you using Diagbox as your diagnostic software and have you ran a complete global diagnostic if you are?
We never really knew what the original problem issue was, but have been just supplying the info that you have requested for various replacements that you've requested.
Are there any dash warnings, is the car turning over? is the immobiliser / Engine ECU unlocked?
If you can't start it, and in the absence of any fault codes, then you may need to get it to a specialist to work on. There's not a lot we can do remotely without any fault codes to go on realistically.

Re: Citroen C5 2009 EGR valve
No, I don't have Diagbox diagnostic, but are using another manufacture. Its no special fault codes related to starting problems.
The main problem was that the EGR valve lost the covering metal on the bottom, and the heat coming out from the valve melted det fuel sensor og en fuel rail. So now I changed the sensor, and EGR valve.
But last time Ive tried to start the car, the EGR valve was not fitted yet. Can that be the problem? I haven't gotten time to fix it yet and retry.

Re: Citroen C5 2009 EGR valve
Ok, now I finally got the car started, but I am not still satisfied yet, the engine power is weak. What could it be? I have changed the EGR valve and the fuel pressure sensor, and im 100% sure that I made the right joints on the fuel pressure sensor cables.
