Hello i have in garage a Ford Focus 2.0 Tdci 136hp 2005 year, the car don't start, i try with other wiring harnes and with other ecu and i have same DTCs (except imovilizer with other used ecu)

i add document file

can help me?

All you fault codes about short circuit, u still have some where short or open circuit
ground from battery ? wiring to EGR/injectors clear ?


i try with other wiring harnesDTCs not means brand new that did possibility of same bad/shorted wiring


and with other ecu and i have same DTCs its clear pointing that u still have wiring problem or shorted sensor

Thanks for reply i don't check for sensor on short(that may be a posibility and now i think it is the more possible). The car not star about 8 month and is very hackneyed for many mechanical that can't star the car.

You are on correct answer, the pressure sensor of turbocharger is in short. The car now start! Thanks!!!

And all the other faultcodes disepered because they chare same voltage from ECU, right.
Dead short or voltage drop ?

I assume directly short circuit, these liked do it after corrosion or overheating. U can found what is principal of these sensors when you understand why they shorting :)

Have heard about other sensors that also can get shorted,
Anyway its quick to connect voltmeter on same rail and start rip off connectors.

Yep but sometime we all need some simple mind / idea from somewhere from somebody. Some time, when have much experience u starting search too deep and forget check first simple things
