Yes you do, the common rail fuel pressure sensor is saying the fuel control regulator on the other side, it is not working correctly, assuming we don't have wiring fault or upstream problem, which is why you test with a multimeter to figure out what the ECU is DTC'ing on.

Some diagnostics will have the ability to do more than read DTC.


Does this make it a warranty issue ?

Where is the fuel control regulator located? Is it in the ECU itself? How do I test it with a multimeter? If you can give more details, I would appreciate it.

Are you comfortable to bleed the HP side of the injectors/common rail, if not might be easier to pass to a diesel mechanic, if not a wiring issue ?
The sensors are usually on each end of the common rail. One is the fuel pressure sensor (which is detecting the error, may be in error) and the fuel regulator is on the other. Till I look the DTC up this is general advice only.

Need the EDC from the VIN.

DTC P0611 Fuel injection control unit performance.
Cant go any further with Haynes on this, will need whole VIN and the DAM/RPO to look into Peugeot Wiring Diagrams.

What pressure is the diagnostics showing at start and idle ?
What are you using for diagnostics ?
And how did we arrive at your resetting the injectors (ECU) ?


Wires don't always play nice and go high Ohm's. An effective repair might be to replace the wiring involved. Sometimes just saves on, fixing at one place to find another one and so forth.

I use diagbox. I'm leaving now and I'll measure everything via diagbox and send you pictures. And I coded the injectors, the error is still present.

Did you code them from 1 being at the transmssion side ?

If you changed the injectors, did you bleed the air out of the common rail and each injector ?
(does it start immediately or have trouble starting as well)

No, I didn't change anything. I bought the car 20 days ago and it had that error. The error is constant and cannot be deleted. I coded just like you said.

Oh man I did everything as you said. Took off all the sensors and vented them. So are the injectors. The error is still present. The problem will be the ECU itself. 😨

 

[DuleKerez]

hey ,did you solved the problem ?

Nou 🙂‍↕

thanks for the the useful info RedSector ,mine is acting up after the fuel temperature passes 72° or so ,and from what I'm seeing my voltage is also invalid ,I'm curios what should that read .by the way can't find it as a standalone part ,I think it comes only with the fuel line ...which is a bummer .and from the looks ov it the filter is the heater as well?

Hello, today I looked at the fuel temperature on the diagbox and it tells me that it is fine. it shows me 3 degrees higher than the outside temperature. Of course it also says INVALID VOLTAGE. Now, if it is defective, it would also show incorrect temperature readings. Isn't it? These days I'm going to clean the EGR valve and everything related to it (because my engine shakes a lot at idle and the consumption beeps) and I'll report the results. I have no answer for DTC P0611 and I still don't know what it is. What error is Diagbox showing you? I would like it if you could take a picture of the computer wiring if you have a 2.2 HDI engine. As you can see, my cables are cut. I'm curious if it's the bark like that or...

Just because the temperature sensor reads correctly when the fuel is at ambient temperature it doesn't mean it will read correctly when warm. For example when the thermistor get warm it can become open circuit. It would be worth repeating your check after the engine has been running.

I had thermistors which worked at 25 ˚C but short circuited a different temperature.

Good. I'll test. The problem is that I don't know where to buy it. Because there is no number on it. And I can't find the same one anywhere, at least by appearance. Was there any alternative? Another, replacement sensor?

This is simply because I may use it, check against my engine 4HN, 4HK of the 4007, the Peugeot wiring diagrams are crap compared (really lack this level of detail, just PDF that been scanned in).

Hello. Could you see which crankshaft sensor goes there? Number or shape, whatever. To remove it, do you have to remove the wheel? Thanks

 

[DuleKerez]

Hello. Can you explain to me how to code the injectors? I know you said that it can't be done if there is a fault with the engine. Believe it or not, it works. I can also take a picture for you, because I changed their places. (experimented) I'm just wondering if all 10 numbers or the first 9 are entered? And the first injector is the one from the battery? And my problem could be related to the crankshaft sensor. How to measure the correctness of the sensor? They have two, don't they? Because the engine shakes at idle, even the front wheels shake a little.
