V70 2006 D5 185HP EGR throttle position sensor - Powerloss

[Calle799]

(First of all, sorry if i make this repost, i maked a thread in VOLVO V70 00-07 first but then i found this Diesel engine thread, hope it is ok)

Hello,

I got some problems with my Volvo V70 2006 D5 185HP. I was out and driving like usual and suddenly i lost a lot of power and a message that the engine needs service.

I took my Delphi computer and got 3 fault codes. 1 for the swirl link,1 for the Glow plug control (P6665) and the last one for the EGR throttle position sensor faulty signal (P44B0 / P4450)

The first ting i checked was the swirl arm, it was boken. I buyed a new arm and a new link/flaps and installed it. The old one was not in good condition. One falut code gone but still powerloss..

The glowplug fault code comes and goes. I think this one has nothing with the powerloss to do.

So, the big problem is the EGR throttle position sensor faulty signal... I have cleand the EGR, hoosing and the throttle. I have replace the black electronic cover that is on the EGR and i still have the same issue. The code comes back as soon as i start the engine and powerloss it feels like the car has 50 HP. The parameters for the EGR is stuck on 99.94%.

So what should i check.. Anybody have any ideas, Could it be vacuumleaks? Bad sensors? Electrical issue?

Best regards

I changed the EGR valve incl. the EGR cooler. The car is running perfectly now
