The engine serial number is not available. I would sugest dyno that way you will get a better picture of what's really going on.But let me tell you I don't know how heavy your loads are but this setup is kind of weak for loads over 35000 and it will pull but it lacks power and strugles and mpg drops.The auto trany is suppose to read the data as far as load weight and driving conditions and adjust to that.Also the way you drive it can be a factor too you have to kind of help it shift,speed up a little before you star climbing that hill but in most cases you'll be the last one on the top depending on your weight and also your differential ratio.And if you keep flooring the gas pedal it will only burn more fuel it won't go any faster.But you may also have a leak somewhere it could be sucking air Or exaust leak or something that causes this.I have an 07 780 d12 engine eaton 10 speed fully automatic and geting 6.8 to 7.5 mpg with minimum idling.My differentials are 3.42 and my loads are arround 20000 but when I get a 39000 pound load its another story.The other day 5mpg Boston to Charlotte via i-81 39000 in the box.Just an example.Good, used fan clutch from a 1995 Volvo VE D12 engine. This is just an example of what I have seen. On a problem with a C9 cat the engine was on the dyno and showed about 200HP under rated hp, because the ABS/ATC system was putting it in a derate. Both systems ABS/ATC and auto trans have the ability to reduce the engines power dramatically.

One is the ABS/ATC and on some models if it has a auto trans(not a autoshift manual, a true auto trans).

The other way to get an engine derate is thorugh the Datalink network - some systems have the ability to derate the engine. I wouldnt think this would be the case on yours because that would flag a check engine code. One is if the ECM detects a problem with a system, example of this would be high coolant temperature, not critically high, but high enough that the ecm turns the power down on the engine to try to reduce the temperature before it reaches a critical stage where the engine will shut down. But to answer your question what is it - derate can in my experience (on other vehicles) happen two ways. I didnt know Volvo engines had a Degraded mode, atleast I have never seen it. but still not sure what pressure is the right one for this engine and if its too high could it hurt the engine?Īny suggestions will be greatly appreciated.

Today I'm going to check physically fuel pressure after the pump. EGR valves been changed 60k miles ago and dont give any codes so I consider them to be OKĬant tell if engine takes oil but pipes that goes from valve cover are clean and no smoke is coming out of them like I saw on some Detroit engines. I've changed oil fuel air and antifreeze filters, adjusted valves and checked injectors by disconnecting them one at the time with the VACDS software. I have to mention that my friend has exactly same engine and his truck averages over 6 mpg and in his truck response to throttle pedal is like in some sports cars comparing to mine truck.

Dealer says it suppose to be around 45 at idle and over 60 a high rpm, when I call VOLVO of US hot-line they give me 15 psi and 45.

VCADS software shows 32 psi on idle and 64 at higher throttle like 1650 rpm. The only thing that is totally unclear is fuel pressure. Turbo boost under higher rpm shows a little over 30. Went to the dealer to check codes - no codes at all. On flat road it takes really long time to change it from 9th to 10th gear. Truck averages 4mpg and totally has no power on higher gears( 7-10) Low gears are quite ok but still not the way it supposed to be. Just bought 05 Volvo 630 with VED D12 465HP engine, 10 speed auto-shift, 630k miles.
