Jackwhoo, if that's right why is the recounter not turning on easy start ?????
The crank sensor provides a voltage signal to the ecu . The sensor is "dumb" and does not require any power or voltage from the ecu. So you would not expect a particular voltage at the ecu side of crank sensor wiring.Thank you jackwhoo, i will have a look at the old one
But i think my problem is only 2.5 volts coming from the ecu to the crank sensor
Perhaps I have said this before? In my understanding the crank sensor is a 2 wire device, with a screened cable. That is what the lower RHS corner of the attached diagram suggests to me. How about Red & White = signal to ECU, Black = screen to earth via ECU?Hi jackwhoo, Just read your last post, thanks, the crank sensor that i have is a three wire sensor, red power from ecu 5v black earth and white signal form crank sensor to the ecu.
But as i have said i only have 2.5v from the ecu
I might be wrong but i think you are taking about a two wire crank sensor
I had great service from this place...I'm back, like a bad penny, sorry been away,
I sent the ecu to ECU testing, just had a email to say they do not have the equipment to test it.
Please can some one recommend a repair place the can test and repair the ECU
If as I suspect the ECU port is just an input connection, you would be seeing an internal biasing voltage via a high resistance. Your meter could be less sensitive than that used on Utube. This would result in a lower reading. Perhaps some research into the Bosch crankshaft sensor would resolve your conundrum.Communicator, thanks for the reply, but please if possible tell me why i have 2.5v coming out of the ecu going to the crank senser and ECU tuning has a youtube video saying that it is 5v coming out of the ecu
as you can see i am confused
Eternal, thanks, i will phone them
