I bought 3 encoders(revision C from china, the orignal is revision B) but still getting the speed sensor errors. Checked the wiring from the sensor to the inverter conector and it is ok.

The motor rotates normal but in a random time it stop rotating(before was every 15-30min now is 3 to 8 min) and shows the speed sensor issue, if i shutdown the car and put it in drive it works even with the error showing but again stop working in a few minutes. Also uploaded the gateway firmware trying to fix this.

I'll try to check with the osciloscope the encoder signals just to confirm that the old and new encoders are ok.

What do you think what could be? Any insight will be appreciated.

Hi,

After checking this post, thanks to Volodimir Leshchenko. Besides the continuity check was ok on the connector. I have soldered the connector on the main board of the inverter . Then I partialy assambled the drivetrain and it worked without any issue for 45min of testing. Right now I'm waiting for LDU coolant cap and drive shaft seals to complete the assambly of the car and get it completly testing.

I'll posting the results after receiving the parts and test, about 2 weeks from now.

Bad news, i was just trying to see if it still working while waiting for the parts i had order, but now the error just pop out within 30 seconds after left the brake pedal.
I had to disassamble the motor again and pulled back the board, i had checked continuity but still ok, so i will remove completly the connector clean all the pads and weld again the connector back. I'll post again the result.
