jeepwm69 7,399 Posted October 19, 2020 Good morning ... from Argentina I have a 2018 TRX 420tm 4x2 and it accuses me of failure 23. Two slow flashes and three fast flashes when I give contact. Can you help me thanks Cheers 1 Share this post Link to post Share on other sites
jeepwm69 7,399 Posted October 19, 2020 Cuando el indicador de marcha parpadea "-" Code 23, es el sensor de ángulo de cambio. Solo en modelos DCT y ES. Cuando el indicador de mantenimiento (llave) parpadea, el código 23 es el sensor 02. La máquina no presenta síntomas negativos, actúa normalmente. Si es el sensor de ángulo, es el n. ° 13 en el esquema, el número de pieza es 38800-HR3-A21 https://www.partzilla.com/catalog/honda/atv/2018/trx420tm1-a-rancher-es/rear-crankcase-cover Si es la llave que parpadea, es el sensor 02, que es parte 36531-HR3-A21 #8 here. https://www.partzilla.com/catalog/honda/atv/2018/trx420tm1-a-rancher-es/exhaust-muffler 1 Share this post Link to post Share on other sites

From what I found (and keep in mind I'm not real savvy on the 14-up machines) if the wrench is blinking 23, it's the 02 sensor. If the gear position is blinking 23, it's the angle sensor. I would think a TM would be a 2wd, footshift, but both of the schematics that partizilla show a 420TM and the description says "420 Rancher ES" https://www.partzilla.com/catalog/honda/atv/2018 I'm going to go with it's a footshift and has a bad 02 sensor. 2 Share this post Link to post Share on other sites

shadetree 5,770 Posted October 23, 2020 OP. the newer 420 models have a known issue with bad O2 sensors from the factory, i believe honda has an updated O2 part for the fix ?. 1 Share this post Link to post Share on other sites
TBRider 1,392 Posted October 24, 2020 Its not a bad O2 sensor, its the multiple short starts and using the cheapest fuel man can find. 1 Share this post Link to post Share on other sites

TBRider 1,392 Posted October 24, 2020 Get a new O2 sensor and the code will go away, try and always use hi test fuel and make sure the engine gets hot after starting it. Share this post Link to post Share on other sites
rustynut2 112 Posted November 2, 2020 Its not cheap fuel. I'm running ethanol free $$ gas and am on my 2nd o2 sensor. Hopefully put an original one in it the 1st time and not a updated one Share this post Link to post Share on other sites
