I'm having a very strange issue with my Honda Fit 2014/17. It starts with the error code "P0339", which is related to the Crankshaft position sensor, and the car automatically turns off without any jerk or anything in the middle of the drive. I got the crackshaft position sensor of my car replaced, and the error code is gone and never appeared again, but this turning off of the car still happens from time to time, not that frequently now, but it still happens, especially during the bumper to bumper traffic. The thing that I observe is that it normally happens when the car switches from EV mode to engine or from engine to EV mode.

I'll be grateful if some expert here gives me advice or suggestions on how to deal with this problem and get it resolved. I have already consulted multiple reliable mechanics, but they are unable to rectify this issue whatsoever.

sir @alibintahir since it is a hybrid vehicle take vehicle to workshop connect scanner and reset the ecu (re-learn). manually you can do it by starting the vehicle warm up. turn off engine remove primary 12 v battery negative terminal for 10 minutes. reconnect and start engine leave it to idle for 10 minutes, process is known as ECU re-learn.

Okay, I'll give it a try. Thanks.

By the way, can the ECU be reset by connecting the scanner or the mechanic in the workshop follow the same procedure that you suggested to me? @sardarg

I think I have mistakenly posted a duplicate thread, please remove it if you can. @sardarg

sir @alibintahir if you connect the scanner you will get complete history of fault codes (earlier & currect) stored in the ECU that will help you identify & rectify all possible issues. by removing battery terminal to reset ECU is blind reset without knowing what may recurs again.

Like sardarg said, clear the codes using scanner or remove battery for a couple of minutes.

If problem still persists, you have to check continuity between sensor's connector and ECU's connector. For that you need to get wiring diagram. Pretty sure you can have fun being electrical engineer

Need to find it's service manual to get detailed solution regarding error code.
