What else could a code 23 be besides angle sensor. 2014 trx420fa1
Currently not showing any codes. Will run and shift fine for a while, then quit switching gears. Doesn’t matter if I’m in automatic or using electric shift. Redid all connections, 3rd angle sensor installed, checked shift motor, changed out the grease. Honda electric shift nothing but trouble !!! Checked continuity on almost every switch on bike. Could it be the gears inside. Currently at idle it will go to reverse, nuetral, 1st,2nd and 3rd. Then freeze up, will not downshift until you turn it off and back on. Also emergency shifter seems to work fine.
Also installed a new shift motor, all gears looked perfect. Sometimes it will show nuetral on display but will actually be in first. Have to rock bike and downshift to get in nuetral

If no codes, the service manual says it could be the TP sensor, either VS sensor, either shift solenoid valve, or low hydraulic oil pressure.

It was giving a code 22 until I put last shift position sensor on. Now every once in a while I’ll get code 23
