Thanks Mike but I think you misinterpreted my question or I wasn't clear. Basically I think we have hit a dead end here & I'm not sure if there is much more we can do that is accurate enough to give us anything meaningful moving forward, perhaps you disagree?
The sensor voltage is either being pulled down by another component on the car somewhere & finding this without accurate info on what other component values etc should be is very difficult, not to mention gaining access to them. Or the ECU is faulty but then what has caused it to fail is vital to find out if it has to be replaced. Catch 22.
Baring in mind how much time i've been off the road now, how much I have spent on it & how much it would cost for a Peugeot dealer to look at it, I am seriously having to consider selling it for spares or repair.
No, you're good max, I think we're on the same page.
In respect of a definitive daignosis, I agree that probing for a potentially obviously low resistance is sort of pissing in the wind without the data for each circuit/component. Alternatively you could disconnect each other sensor/actuator circuit and see if the 5v magically re-appears.... but that requires a lot more yoga, as you say.
That's the last option I can come up with at this point.
Equally, all the prior suggestions including to read live data is only valid if you see any value in fixing your car, but also happy to help if I can. I think it's a nice enough car and a pity to get shot of after all you've invested in it, given the only definitive evidence we have of it being a non-runner so far is bad ECT data.
