FAQ EDC Pumps / W202/W210 W463 ECU’s
Ive checked the mercedes service manual and the fuel solenoid on startup receives 4V, i have not measured it myself under load.
The rack position sensor at idle should read 1.95v from the pump data sheet.
But its not just purely based on voltage either, it uses a sine wave to measure inductance changes to give feedback position for reference and rack.
