I was not able to determine which sensor is bad. Can I test the sensors?
My car is a 2001 Z3 2.5

I cannot answer your question but wanted to welcome you. I know that on the early model M roadsters there was a recall or TSB involving the camshaft position sensor. Have you checked with your dealer?

The sensors are known as Hall Effect sensors. They can be tested, but you would need to remove the sensor so you could wave a block of steel in front of it, and observe the output signal with a scope or meter. That also means you would need an electrical diagram to make the proper test connections.
