I’ve replaced the sensor as it was out of range using a multimeter. If replacing the electronic control board doesn’t fix the error, how do I check the wiring to confirm it’s good?

Depends on the model. On most ranges the wire goes diretly from the sensor to the board so replacing the sensor would solve any wiring issues. If the sensor wire plugs into another wire before gettting to the board then you would check continuity on the wire the sensor plugs in to, between where the sensor plugs in and the board.
