Peugeot 207 1.4 HDI: Antipollution Fault, Loss of Power, P1166 High Diesel Pressure Issue

This misfortune met me with this depressing message. By default, the message Antipollution System Fault appeared on the display and CHECK was lit. The car only goes out at longer journeys and faster speeds. I changed the fuel filter and the air filter, a few days on short trips was calm (no message was released and even CHECK disappeared). However, today on a longer route, the message + CHECK popped up, the car started to jerk, lose power and finally went out. The car could not be started, it took several minutes before the car started. More than once, as if it would fire up, it will jump in revolutions and go out again. Somehow I fired after 20 minutes and returned home. After some hour I went down to go to a friend to the computer (there was neither a message nor a CHECK). The car started and drove normally. I went to a friend to connect the car to Diagbox. An error has occurred:

I noticed that after the car went out, the fuel system became airy. For the car to start it needs to be pumped up with a pear. There are evident air bubbles in the hose. Fuel and air filter and pressure regulator replaced. Fuel tank clean.

Anyone have any ideas?

Check the tightness of the fuel lines, also the toilet pump to check.

Hi!
If you remove a set of pears with wires from the engine compartment, you will find a worn wire. To replace the whole (original PLN 600) or repair at the place of abrasion.

To see these hoses, I have to dismantle the air filter together with the housing, so by the way I will replace the fuel pressure sensor as soon as I have access. I don't have time to deal with it yet. I will take it on days and let me know if I found the culprit.

Hi!
The pressure sensor is a common malfunction, but you have rather a fault for fuel shortages, besides, you need to pump up before firing, but I focus on rubbing the pear circuit wire.

The wires are slightly worn, but not through and I do not see any signs of fuel leakage. I replaced the sensor. Soon I'm going on a longer route to test the car.
Tenths 1 must be pumped only when it goes out while driving. In the morning with firing I have no problems, it smokes with a touch. I'll let you know in the evening whether changing the sensor has helped.

Car tested on a route of about 40 km one way, where 30 km is an express road. The car did not go out and it was probably a matter of replacing the sensor. I'll go and watch. We'll see over time. I will let you know in a week or two or if the fault persists.

Hi!
If you do not pump in the morning, this is not a pear wire, but sooner a sensor, although in the future knock on unpainted, as the pear wire is wiped, it is in one place, it is dry, but it already takes the left air, tested in many Peugeots 1.4 hdi.

A month has passed since the pressure sensor on the rail was replaced and there is peace, so he was the culprit.
