Engine light flashing

[toodeep 1,758]

This seems to be a pretty common topic on the 2014+ Foreman and Ranchers and 2015+ Rubicon. The engine light is flashing 2 long blinks and 3 short blinks, giving a code 23. That is the code for the O2 sensor. The motor will operate normally with that code so no worries there, continue riding until you fix it. The fix is replace the O2 sensor or find a delete kit. It's a really simple fix being just in front of the left rear tire. Get a new sensor, unplug the old sensor, remove old/install new and plug it in. The code will go away but will be stored in the memory (no problems with that).  The most common reason for them going bad is a lot of short run cycles not letting the exhaust get up to temp (dealer moving around parking lot, back and forth to the shed).
