Yeah that's what I was thinking as well

Absolute BS, they know exactly what they order,change, update, etc etc.... CFMoto has been around for 26 years, they may not have all the bugs worked out of every  model, but they are aware of any and all parts available and where they go.

Well I called them again this morning and they said the parts still haven't arrived I think they ordered them last Tuesday and they said if they arrived today then they wouldn't be able to work on until tomorrow because the mechanic is off today

Dealer finally called me they said they put the new sensor in check the voltage on a voltage is the same as a new 2018 said everything checks out normal so the CFMOTO rep told them to keep it and ride it for 20 miles to make sure it was going to work but dealer says they're having a hard time finding time to put mileage on it

Oh brother...

Was looking through the older postings concerning the coolant temperature sensors on the z500 and ran across this one. Does anyone know what the final outcome was for this? I am on my 4th sensor waiting on the dealer to replace under parts warranty. I bench tested the first three one for resistance and all have failed specs according to the service manual page I managed to find online. I tested continuity on the harness to the gauge cluster pigtail connection and it was good. The most recent one apparently was defective before installing because my gauge stayed on one bar from the start. Thanks!

Looks like the OP hasn't been here sense January but send him a PM and the system will send an email to him. Sense you have an old one how about matching the base and threads with someone else's and trying it. Most of these all work the same and are close to the same temp ranges on resistances.  Can't hurt.

I've got an ac delco p/n 19322820 setting in my amazon cart with a replacement three pin wire pigtail if Cfmoto doesn't replace my part or if the next one is bad I'm tired of fooling with um, probably why OP's not on here anymore he was tired of fooling with um lol! Thanks NMK.

Just to clarify a couple things, one bar on the display is the default, you will always have one bar.

The sensor is likely not at fault. The coolant temperature sensor uses the body of the sensor itself for ground, there are several layers of interference for the sensor to receive ground. Dirty threads on the sensor or housing it threads into (thread tape is not required, there is a sealing washer), corrosion between the mating surface of the housing and the head or the sensor housing is not to evenly torqued down.

You can run a quick testing by mechanically attaching a wire to the body of the sensor and attaching the other end to a good ground.

I started a couple more recent threads on my probelm in the z500 section and this section of the forum. I started posting here to hopefully get a response from OP which NMK advised hadn't been on here since January.   I did scotch brited the original sensor surfaces but I didn't disassemble the thermostat housing and scotch brite those surfaces. I'll do that, pitb, draining coolant and all...and we'll  see what happens. Thanks
