E1 code is either a Hall sensor failure in the motor or it could be like 2 i had here where a wire on the hall sensor connector had come loose..
E5 is the white wire that attaches to the motor and is what i believe to be a temp sensor in the motor… i have had 2 controllers with this error and attached a working controller and the E5 goes away, so my thoughts are that this is a fault in the controller and not the motor after disconnecting the white wire the scooter works as normal… This could lead to a failure in the motor later down the line but if you are stuck and need to get home its a quick fix.

I have also had the E4 error and found that a controller had blown a mosfet, i replaced all the mosfets and the controller works again…
I can add the following…
