All OK yes....next test, switch your Meter to AC readings and low value [say 10 / 20 AC ] Meter on pins get someone to crank engine over, you should see to spec below.
OHMS 600-1000K
AC Volts.. 2 /4... depends on how fast Cranking, doing these tests at ECU tests the loom as well.
Thanks for your reply, I have done exactly this, to the letter, which is how I got to this point where I think I have found the problem but don't know how to fix it as both CPS and phase sensor are brand new. I do get 0.1 volts on the phase sensor which should be 2.0 volts too.The missing voltage cannot be generated through ECU as it is not connected. Any further help would be greatly appreciated as if there were cliffs in Canada I would be pushing it over one.
