Hey guys I’m new to this I have a 2016 Honda 420 electric shift 4wd, and my 4wd has been acting weird it won’t engage when I put in 4, but if I ride a little it will engage, sometimes the 4wd letters in my display with come in and out, any ideas? Thanks in advance

Its probably wet harness connectors. Those connectors are not sealed very well from the factory, none of them are waterproofed. So you'll have to take both fenders off and open each connector pair, then dielectric grease each one before snapping them carefully back together. Its time consuming, but its the only choice ya got. Thankfully the tube of dielectric grease that you'll need costs less than 10 bucks. Unhook the battery before you begin and be very thorough... and be very careful with all of those fragile plastic retainers. Get a copy of the service manual before you begin and read it... especially the warnings... Welcome to the forums!

An oxygen sensor? For 4x4 not engaging properly?

most speed sensors are either bolted on/near the front diff ?, or at the back of the motor on that model near the output shaft ?. have a look in the service manual if you can get it from the site here ?.

The 4x4 conector is cliped to the lowest part of the frame, right hand side, clean it and move it up as far as you can.
