They're pretty much all on/around the throttle body area. IAT is intake air temp it's a shared sensor with the MAPlb the suction side the throttle body. You can use a small amount of dielectric grease to help seal the connectors, don't need any on the physical connections themselves. Like I mentioned the errors seem to be all over the place which leads me to suspect a weak ground or other shared electrical connection, rather than a specific sensor. I'm hardly a hisun expert, bit I have a good logical troubeshooting process (rather than throwing parts) and am happy to help where I can. Let me know how it goes and we can try to troubleshoot further.

The real problem, as I see it, is that the codes given are consistent with an engine that's running poorly. So imho, if it's not running with a substantial miss, then something else is going on. Like a possible failure of the CPU. Manufacturers are typically reluctant to give away parts without a reliable, trusted diagnosis of failure, such as that provided by an authorized service center. And a new CPU could be quite expensive, with no guarantee that'll cure the problem. Throwing parts at it is never a good plan anyway. Fixing it yourself, could be a long, expensive, frustrating endeavor. Complete with long down times, and fairly involved diagnostic procedures. If it were me, I'd try to make it Lowe's problem. By any means necessary, including a return.

Hi, not familiar with the brand but speaking from someone who bought a Chinese knock off of one of the major brands just make sure parts are available and will continue to be available. In hindsight I would have rather paid the extra money to buy a name brand, Polaris, Yamaha etc as parts are much easier to come by as well as service manuals and aftermarket items. One last thought, take a look to find out if there is a good support group out there for that brand. I found one for mine at that has been a life saver. I found mine on facebook groups.
