    Fault code p0365

    Hi,
    What could be causing fault code p0365 (camshaft position sensor, exhaust) to appear again every time when the engine is started?
    The car is a MY2001 e39 520i with M54B22, 180k kilometers/112k miles. The following procedures did not work:
    -Changing the exhaust side camshaft pos. sensor (OEM)
    -Changing the crankshaft position sensor (OEM)
    -Checking camshaft pos. sensor's wiring with a multimeter (All ok)

    The fault code can be deleted, but comes once again active when starting engine...

    Advice needed, this is the only thing I need to sort out before we can pass MOT.
    Thanks in advance!

    Do you have 5V at the sensor pin 1 with iggy switch in position 2 (15)?

    I am getting 5V for pin 1 when the ignition switch is at position 2. Strangely the voltage from battery and continous current for the sensor has dropped to 11.2V. With engine running, the voltage is 13.6V for both.
    I have bought a new battery two months ago.
    Could something be draining the battery at startup which could be causing P0365, or is there still something to inspect?

    11.2 is too low, and indicates a dead battery. What is the overnight battery voltage w/o starting the engine? The E39 is very sensitive to battery voltage.

    Finding parasitic current drain

    An article in Motor magazine suggests this approach: measure the voltage drop across the fuse. It s/b zero. If you measure several (or more) millivolts, you can consider that circuit suspicious.

    Some modules do not take kindly to pulling fuses, and you may encounter a lockup or damage. This approach avoids that, as well as the hassle of pulling fuses.

    Also, this can identify blown fuses, where you will measure the battery voltage.

    Here’s a table that relates current drain to voltage drop across fuses:
