Multiecuscan

Hello!

I can't read Injectors correction on EDC15C7
When i mark the checkbox there only appears "mg/I" but there is no value...
The car is Lancia Lybra 2,4 and Alfa Romeo 166 2,4
Also i can't read the fuel temperature (but only in Lybra)?!?!
I've tested it on KKL, ELM, on my registered ECUScan and on another computer whit unregistered version

(By the way, my problem is fault: "P0191 - Diesel pressure control; Invalid signal; Fatal; Light ON"
it happens when car is on hi load and pass 3'000rpm
when fault occures, fuel pressure is much lower then desired fuel pressure (for example: 1350/760 bar)
car: Lybra 2,4)

Any ideas?

hi dave here had this a few times the most likely cause is excessive injector back leakage
you will need to do a test with backleakage test kit to confirm
also had one with this code intermittantly and it turned out to be a faulty fuel pump relay overheating and cut out on over run
