Error 21 and 00

[E-bobby]

Hi guys, today I bought a 2021 carrera vengeance e bike, it has error 00 and 21 I knew it had a error 21 and thought that there was no speed sensor on it, I turned the bike over and it was below the crank, I then repositioned it to the correct place and put some wd40 in the connections, then I put the battery on and the display showed the speed and mileage etc, then it threw it self back into error mode this time error 00, (I do have a smashed display so maybe that’s it) and then I turned the bike off and back on then error 21 appeared again. Any advice on this? Also I’m looking to buy a throttle and wondered if I can bypass the speed sensor if I buy one so it doesn’t show the code, any recommendations for a cheap but reliable throttle? Thanks guys.

What happens when you disconnect the torque sensor?

Error 21 still continues, I’m not sure because it looks fine, I will post a picture of the sensor itself and see if I need to buy a new one. Thanks

Hi I bought a new one just before as I took the sensor off again and had a close inspection, it doesn’t look good but wondering would it still work, here it is. Would a new sensor sort this issue and if not what else could it be. Thanks

There should be a cable tie around the blaxk sleeving to stop it pulling the wires off. The only way to know if a wire is off is to dig out the silicone rubber. Underneath is a connector. If youfind a broken wire you can solder it.. that's about it.
