Throttle gives out too much ref voltage and doesn't go high

[elt93]

Hi Guys,
I just got a problem out of nowhere on my ebike. The throttle output voltage is suddenly at 2.2V instead of 0.8V at zero user input. SImilarly, it only goes up to 3.3V instead of 3.6 upon user input. What could this be due to and how can I solve it?
Thanks you for your help!

Sounds like a bad hall sensor.

Double check that you have 5 volts reaching the throttle. a bad connector or wire could cause low voltage or a faulty ground. then the hall wouldn't function right.

If the connector is good, you have a hard choice to make. order a $3 Hall sensor and spend an hour or two of your life stripping, soldering, and rebuilding your controller, or ordering a new $6.89 throttle. Example

Oh thank you! The hall sensor is probably broken, I will buy a new throttle!
