Daf 105 460 Engine Warning: Reducing Power, Fuel Temp Sensor & Filter Issues on 1600km Route

Question

Hello, I have a problem. Daf on the 1600 km route displayed a warning engine in red about 7 times and lost power but there was no warning about the loss of power. The computer sintering was caused by errors from the fuel temperature sensor. I exchanged it and then the same goes on from time to...

Hello - the problem can be with fuel pressure
check the actual fuel pressure with the pressure gauge. You do it by turning the fuel pressure sensor and connecting the manometer. The pressure should be about 5 bar at idle. If it is not, or "wavers" from 1 to 2-3 bar, replace the feed pump.
EBS will not reduce power. greetings
ps check also if the "Christmas tree" in the fuel filter housing is not damaged.

I think that if the pump would sit it would not be pressure and the computer would indicate 5 bar. Jaltest always shows it well. There are no saved errors in dmci here. The filter and the basis of the new spring in the arm removed the lichen I have no idea what to take

Hello. As for the fuel pressure and temperature sensor, it has "made me into a horse" several times. Check that the pressure stays constant at 5 bar or if it changes after adding gas. If it keeps "rigid" the sensor is damaged.
I suggest you go to someone who has a DAVIE and do a fan test and test the performance of the cylinders, unless jaltest can do it. greetings

The pressure jumps around 5 bar is also ok. But it arrived and the errors are further away from the temperature and pressure sensor A it is New. Here, I rather do not put up for the installation: / the error turns on and goes off while driving or is it possible that a new duplex sensor?

Maybe there is some glitch in dmci, or some software error. It must be that dmci is not unreliable, but appearances are wrong.

Hello, when it comes to pressure and temperature sensors, in the last month I exchanged 3 or 4 (new), and DAF included the complaint! Try to replace the sensor with another car. Regarding errors - are there only errors in the pressure sensor, or temperature and pressure?
Last week I fought with DAF, who did not want to go, and made big blue eyes when it turned out that there was a piece of plastic in the tank that blocked the fuel. Look into the tank, maybe something floats on the bottom. I'm honest

The temperature and pressure sensor error appears. Power supply 5v has, apropo fuel I have already looked at everything today I replaced the fuel filter and separator on the original. Because there was a mistake too low pressure. Zaworek in arm pulled out to be honest I did not have such a case. It will replace the sensor as you handled me, the car will fly on the route and we'll see I'll know. I did a road test with a computer that you know on the wheel of 5 and when we were driving 6 .6.5 and it did not catch a bad error. Well, let's see if this is not my next step, it will be a power pump because maybe something takes it already

in my dafa an error of low fuel pressure appeared in the course of about 950,000 km. 2-3 times a week. but the pump was already falling because the pressure in the idle gear was jumping from 1 to 2 bars. after replacing for a new 4-5. if you have 5, you have a pump.

serwis33 · Answer

Hello I agree with szy18 - if there is a pressure of about 5 bar, the feed pump is efficient and does not need to be replaced. If you have the option to do this, test the performance of the cylinders, you can deduce from it whether something happens with the unit pumps and injectors. greetings

Hello. I replaced the fuel filter and separator with original dafoski and everything hula. I also warn you how you want to save money on fuel filters, but it does not go. Apparently their bandwidth is different

serwis33 · Answer

Hello, and where did the non-original fuel filter and separator come from in your car? There is so much crap on the market now that I only assemble original filters and sealants in DAFs. greetings
