Brand New TRX420FM1 - PGM-FI Light

Light is on steady when driving any speed - less than .5 hours total runtime on ATV. Anything I should check first? Manual says to reduce speed and take to dealer immediately.

Code 23 is for the O2, it’s a quick fix but that’s also what the warranty is for. If the light is on steady then I’m not so sure that that is the issue...

Some more info: When ignition switch is on or engine is idling the engine light (PGM-FI) loops with 2 long flashes followed by 3 short flashes. When quad is moving light is lit steady.

yep that's code 23, O2 sensor it is.
