Hi,
I have a 2007 ford focus 1.6tdci with a P042f code:- Exhaust gas recirculation (EGR) valve actuator A – actuator stuck closed, I've replaced with a new EGR and still the same code, so with a multimeter i checked the the wiring, i got:
pin 1- 5v ref
pin 2- 2.6 i think is signal
pin 3- 0.14
pin 4- 0.48
pin 5- 0.01 ground
should i have 12v on one of pin 3 or 4 or is it power side switched. Thanks
Taking Voltmeter readings at one end is a great start but by no means is it "Checking Wiring"
For that you will need access to an accurate wiring diagram so it can all begin to make sense. And of course it would be a good idea to look at feedback whilst it is being activated and moving from stop to stop.

Hello,
About P042F fault code I have some bad news...replacing EGR and adapting the new one in ECU will not solve the issue,but replacing ECU(in my case) yes.
I think you must scope the feedback signal from EGR vs actuation(curent or voltage)

Hi if you give me reg via pm Il email you factory diagram , this dtc is usually a pcm fault with motor circuit pal but send me over reg or vin and Il give you all help I can .
