P1624- Pedal Position Sensor Potentiometer Supply Channel 1 Electrical.
The Siemens MSE43.0 Engine mamagement module is used on more than one model. The different meanings of the P1624 are based on your model.

The P1624 referenced here is for the MS43.0 engine management module with a note for M52 engines (323 / 328) that it is a coolant temperature below thermostat regulating temperature. You should have a M52 engine.

The MS42.0 engine mangement does not list a P1624 code in the Bentley manual.

The fault above cold be set due to the following:· Break/open in the wiring from the DME to the throttle motor(MDK).· The actuator or potentiometers inside the MDK could be contaminated.SOLUTION:
(If any of the faults listed are set) · Using a breakout box check for an open or short to ground in the wiring from the DME to the MDK.· If the wiring is intact then replace the MDK, then the adaptation values in the DME must be
cleared. Failure to do this will result in reoccurring faults.· Switch the ignition off for 30 seconds.· Turn on the ignition and delete the DME adaptations and the fault code
memory · Press the accelerator pedal to wide open throttle(WOT)4 times
MDK- motor driven throttle valve.

    Sure, it is easy to say Break out box and test it, but what is the testing procedure.
    which contacts or wires are the ones to tap into for the potentiometer?

I would advise you get the problem code read at a garage asap, to find out what the problem is, this will also tell you how urgent the repairs need to be done.
