CBR650F cbr650f crank no start

Don't remove the tps. It's a factory set unit that comes with the throttle bodies.

Test the wires/sensor first (in place), manual has diagnostic tests detailed.

If you need a new sensor, then let's talk about removal.

Thank you I have downloaded something similar to this one. I'll go over it see if any difference

So I put new fresh gas same thing. I do notice now cylinders light up when I have the throttle open slightly or wide open. I also notice that the stator and flywheel it's what is being called has some rub marks. Like at one point it was hitting. I'll test the crank sensor next. seems like it wants to start though

Really you'd resolve things more quickly using a code reader. A search on here should help you find the right connector. I have a 2023 CBR650R, which has a different connector, being Euro V compliant. As you have said, it's weird that it cranks with the ECU disconnected.....

The obd2 adapter finally came and when I try to read the codes, and error message comes up, idk if it's my obd2 scanner or cable or is there something wrong with my ecu? Yes the scanner works I use it on other cars

I think only 2021 - up is OBD2 compliant. I saw a post by someone with a 2020 use a generic scan tool though, so I'm not sure.

A quick search on ebay etc will find the adapter and or reader you're looking for.
