2019 MT82 D4 Trouble shooting

[K1514]

2019 Bullitt and I am getting an intermittent P1934 code. I am also getting tons of warnings on the dash one after another, park aid fault, blind spot system fault, cross traffic system fault, see manual with the wrench, and occasionally I loose my speed reading. I can clear the code and then if I get the dash warnings I do not necessarily get the CEL with the P1934 code again. P1934 indicates a trans speed sensor which I cannot even verify even exists on this trans. The only sensor I can find is a 6 pin on top drivers side, cant find any info on it.

It has to be something with the sensor on the driver’s side of the tranny. I‘ve had my Bullitt’s D4 completely apart and can confirm that there are no other electric sensors on/inside the tranny. See post #85 for interval magnet that work in conjunction with the aforementioned sensor.

Have you changed your clutch recently? If so, did you do a crank relearn to see if that clears up your issue?

Somerhing else to check and clean is your rear ABS sensors. If they get gunked up they will throw lots of codes. Spray them down good with brake and parts cleaner and wipe them down with a rag. I believe the tranny sensor and several other systems communicate with each other and if something is off in one area it could affect another.

Yes I did change the clutch but this issue was happening before the clutch change. I was hoping the clutch change would fix it. I did another crank relearn procedure today and I am going to clean the abs sensors. stay tuned.

I believe that sensor only exists for shift fork position for the active rev matching but I could be wrong. Speed should come from abs system
