Solid check engine light and code p013116 flashing. 780 miles

I've read that it's an O2 sensor. This happened at around 16 miles but went away on it's own.

I'm no longer under warranty. Any ideas?

Bank #1 O2 sensor low voltage which is the one near the muffler where others have found the lead breaks right at the sensor. There is another thread on a Z this that just happened. Yours is newer..or with lower mileage so if not this its a bad sensor or a bad connector. Unclip the lead and separate the connector and inspect. Clean with only electrical contact cleaner. If no cracking or breaking wires or the code doesn't go away after cleaning the connector, replace the O2 sensor would be my next step. But if you pull the sensor and find that it's carboned-up, there's something going on with that cylinder that needs addressed. You can try burning all the soot off with a propane tourch and blowing it out with air..nothing else but that cylinder may have a ring or valve seal...or a leaking injector problem...

I removed the sensor and this is what it looked like. Checked the plugs and connections are fine. I torched the sensor and blew out with air. Still throwing code

Any O2 sensors that will work for this? Other than OEM

Count the number of wires in the connector. If it's 4, one like this will probably work fine. If something else, still look on ebay. 207 for an O2 sensor is outrageous.

I hope you figured out your code as this post was months ago but I had code P013029 flashing with a check engine light on my 2023 UForce 1000 last summer at 400 miles.  I was told on this forum it was O2 sensor circuit Bank#1, Sensor#1.  I talked with a UTV gearhead in my local bar and he asked me if I had cleaned or changed my air filter yet. We had been having a super dry summer here in MN so he knew I was out driving on all the dirt roads.  I blew out the stock filter and reinstalled and it cleared the code and it never threw the code again.  I ordered a Outerwearers cover UNI Filter after that and haven't had any issues since.

Same motor as z950 ho ex.  A guy on this thread

https://cfmoto-forum.com/alternative-parts/2021-z950-sport-alternate-o2-sensor/

 said he used this one.

$33.  Way better than paying CFMoto $200
