Hallo
Thats how the pictures looks on BMW scope
Thebmwman:
Well
According to the pictures, the sensor should be generating something around 10 volts right?
This sensor is generating barely 500 mv
Take a look at the volts scale on the osciloscope
There is also the volts at the connector
Wiring connector
1 > Sensor output. 11.4 Volts
2 > ground. 0 volts
3 > voltage supply 12V. 12.5 volts
Is there a valid reason why to have just barely 1-volt difference at terminals 1 and 3?
Am I right?
Thebmwman:
Finally, the problem has been solved
A faulty sensor was the problem
However, it took 3 sensors to find a working one (the first 2 purchased at the local dealer)
A Third OEM part from a remote stealer solved the problem
I strongly think the local BMW stealer is selling Chinese BMW spare clones or something like that (not the first time this has happened with other parts)
Even some BMW Motorrad services have been made with HiFlo and Mahale filters as I have seen
Is this something common to happen with the BMW dealers to sell non-OEM spares?
Have someone else experienced the same issues before with the stealers?
sarausa:
This error code indicates that the vehicle's control system cannot receive or process the signal Suika game from the camshaft sensor correctly. This can lead to problems such as difficulty starting the vehicle, unstable operation or loss of power.
