Peugeot 307 1.6 HDi 9HX: P0490 and P1162 EGR EDC16C32 Errors Persisting After Fixes

Hello.

I have a problem with the car as in the topic, Peugeot 308 after lifts, engine 1.6 HDi 9HX without FAP (factory without FAP) - after erasing errors in a few seconds P0490 and P1162 are coming back, even without firing a car. After a longer ride there are other errors with EGR, no EGR position is visible on the live data view. I substituted the new EGR (replacement), but the same thing happens. I checked the 100W bulb passing the wires to the computer - everything's fine. On the EGR execution test, it works like the EGR throttle - I also check the transitions to it, and I can not locate where one cable goes (the rest has a passage).

Also, the reading from the MAF is overvalued by about 200 units at a standstill, while the difference varies, but still is.

I would ask for a schematic of this element (EGR throttle), possibly a schematic diagram of the entire engine installation, as well as for clues - is not this a programming fault that would be arranged by the new software?

All five wires enter the engine controller.

What did you start with EGR (company)? What are you diagnosing? Can you see the driver trying to open?

First, I would do an EGR adaptation.

Made, to no avail.

And this can be a big thank you for this information, I will have a car this week, or I will check it again next time.

There are no opening attempts, the car has been running well for about two years after the purchase, the EGR fault has only appeared this year. EGR EGR, I know it's not the highest shelf, but friends in the store said they did not have any problems with that. I diagnose with Gscan, Launchem, but a friend came with a toy service and readings / errors overlapped.

Ok, how does EGR behave when playing with gas? Can you see the driver trying to drive?

As I remember, the power supply is common to the EGR, the flow meter and the fuel pressure sensor.

In addition, check if you have 5V and not 2.5V.

Give a screenshot of the planet so that I know what mistakes are exactly, I mean description.

From Planet:

P0490 - Electric EGR valve position copy signal
P1162 - Electric EGR valve position copy signal

As for the voltages, then the 5V on the plug from the valve is, the transition to the ECU too. One throttle cable has no ECU transition and I will check how I will have a car.

When viewing live data, it is not possible to read the current EGR position at all.

5v is on plug No. 1 and 12v should be in 3 and mass in 5

Because the valve is blocked due to error p1162.

When this 12V occurs, because after removing the plug and starting the engine, there is nothing - unless at the moment of the drive. In any case, the valve test works on the executive test (I was looking at the new one) so 12V should be.

Adaptation was also made with a suitable - factory - device.

Alexander, from the side of the page, you approach the matter.

Aleksander_01 will you tell me what was the solution to this problem?

I haven't been here for six months, so I'm answering just now. There were two faults there, one was EGR sticking to the mass and the other was in the pipes. It rarely happens, but it does.
