    Crank Shaft Position Sensor 2004 V70r

    Anyone know what volts should be measured on connector (both pins) to CPS with ignition on?
    Cheers

    Without seeing a wiring diagram I could not be certain. So, as it's not a Hall effect sensor (3 pin) it'll be either 12v or (5v from the ECM).
    However, have you checked for an RPM signal in live data first? Why do you think you've got a CSPS fault?

    Just trying to narrow down non-starting issues and ticking off the simple things before moving on. Read that if starter motor draws too much current then it can affect cps and in turn spark. I seem to have intermittent spark. Subsequently had starter checked and it needed refurb. Brushes knocked and sign of overheating. Fingers crossed this is the fix but haven’t got it back on.

    CPS is inductive pick up and I’ve managed to measure about 30mV pick up on oscilloscope off the car. I think this is expected. So hopefully it is starter.

    Thanks

    Basically, if you have a spark then rule out the CPS.
    Check to see if you have a switching signal at the injectors too. Easiest way to check this is plug in a NOID light.
    If it flashes then your CPS is fine. If it dont, check you have 12v too before progressing further.

    Good point, I'll give it a go. However, problem appears to be intermittent spark. When first checked for fuel, air and spark it looked good. Then as I was going round in circles turned out I got lucky seeing spark the first time. So something is upsetting firing order.
    Had started refurbished because it was knacked. So one less thing to check. Cheers
