Hey guys!

I have an Opel Ampera MY12.

The car's electric motor started to act weird, going forward then like hitting on breakes, then the elctric motor stopped. It went full crazy.

The error codes:

P0A46 - Drive motor 2 position sensor performance

P1B04 - Drive motor 2 position sensor circuit tracking lost

I swapped the whole motor to a working one, but since I dont't have the immo PIN to my car, I didn't swap the inverter panel containing the IC/microcontroller which counts the position of the motor.

Both position sensors working fine, so I'm guessing the inverter panel is faulty. Do you guys have any tips what should I check/do before swapping the inverter panel?

Any help appriciated!

Did you go down the route of repairing the original inverter panel, or did you find someone who could handle the IMMO and let you swap in a complete working inverter?
