Technical '06 Panda crank sensor issue.....
Cool
Under 0.2V on the engine while cranking is correct
It's intermittent but at the time of test it's 100% okay
No idea on the ECU I have a euro 5 engine and the ECU is bolted to the engine and a coil pack on top of the valve cover

Do you think i should make a voltage drop between the positive and alternator?

One more thing the light of the shifter lit after trying to crank the 1st time even after removing the key from the ignition then went out all by itself after a while
Yes please, to the stud if possible, I know it's a bit hard to get to

Nah it's easy from the downside up I'm gonna go and do it and hopefully i can manage the starter aswell because it's very well covered
Sound like the tester and not a real fault
These only fire the coils in pair even if there's no mixture to ignite (waste spark)

Ok so i got a steady 0.23 on the starter and 0.28 and drops on the alternator

It means both coils are working because 1 and 2 are both working but wanted to be sure that that's how it should be

Anyway what's next?
How's the battery check light while cranking is
You need to measure while the fault is fault is present

After clearing them all and trying to crank the car won't start and the faults won't show up at any system, the battery and oil lights on the dashboard are now stable, won't go out
No P0335 error?

And one more thing i had this issue when the car was running where i get a vehicle overheating warning while the gauge hits the max then after a few moments aka 2-3 seconds sometimes a little more the gauge comes back all by itself to the middle and the warning goes out dunno if it helps the investigation

Nothing anymore but wait a moment gonna check again after several cranks

Ok so checked again now the p0335 is gone u1700 is gone and even gave a clear fault code command although there was nothing, TCM was empty aswell and ordered a clear, EPS empty aswell and gave a clear fault too dashboard clean too and gave a clear faults as a safety measure and finally the BCM that had the serial line and minicrypt fault codes cleared them, then when i cranked the serial line came back alone and if i crank 2-3 times the minicrypt fault appears again all the other systems are completely empty of faults and forgot to mention the abs as well
Wired directly into the ECU
Sends a voltage out measure the voltage drop after the sensor
Still pointing to an intermittent problem
Still looks likely the reference power or grounds are at fault

What do you mean? What do you want me to test?

Are these the 36 and 45 pins of the ECU loom?
Is that 0.28V voltage drop between the either end of the alternator to starter
Or
Battery negative to alternator
