I need a rear TPMS sensor for my 2017 CVO Limited. Mine is going crazy. Pressure goes to 25 PSI then to 43 PSI and light stays on. What is teh part number?

I think it may be 32700052 but I’d wait for confirmation from others.

32700052 SENSOR ASSY,TIRE PRESSURE,434MH MSRP $102

You can find a few dealers that discount them online, watch the shipping and handling charges, some places offset the discount with BS shipping and handling charges. Something this small should not cost much to ship.

Before I take off the rear tire here is what the TPMS is doing. On the dash it shows 40 PSI cold and then goes to 43 PSI hot. The light stays on. Is it the sensor or something else?

Don’t suppose the light is because of a problem on the front?

Front is OK. It's the rear. Dealer said it was the sensor.

If you check it at the tire are those readings accurate? If so the sensor is doing what it's supposed to. Warning indicator staying on would not suggest to me a bad sensor if the pressure readings are accurate. That's an incorrect use of the data rather than bad data itself.

Only other thing that comes to mind is if the data from the sensor is erratic. Accurate when it's there but perhaps weak battery so it's dropping in and out? Not familiar with the Harley system so no clue how it reports in those cases.

Tire pressure goes way up as the tire gets hot. My rear is set to 4 cold. Yesterday at 94 degrees out side and 80 mph speed for many hours rear was at 49 most the day. No light on.

Front temp goes up also but not as much like 46 hot.

Something with the sensor or bike, not sure. I know they can set where the light comes on for low pressure. Don't think they do that for high pressure.

quality drop between 2015 and 2019 is just huge. I cant believe how bad quality has got, and materials or much less durable.

Seem they figure most only put a couple thousand miles a year on the bike, they will not know the poor quality until the bike is out of warranty.

Dave. On the way over to replace the rotors, the tire sensor failed. Warning light came on. No reading on the front tire. Luckily they had a few on hand. Really amazing to me to see how their stuff doesn't last. Sad really. Stuart.

Hate to harp on an old theme, but once again Harley took a mature technology from the automotive industry and managed to screw it up. As best I can tell the aftermarket TPMS systems have better reliability than the Harley OEM system. That is sad.

Wow, I have only had one replaced

Seems low bidder on everything, very low quality.

Cvostu · « **Reply #15 on:** July 22, 2020, 05:51:00 PM »

Not fun when they fail. The red warning light comes on and so does the low tire light. I'm thinking at about 80 I have a tire going down. I would slow down to about 60 and after about 30 seconds the lights go out and it's reading again. Really bad. Stuart.

muddypaws · « **Reply #16 on:** July 23, 2020, 10:34:24 AM »

So it appears the sensor is reading correct for the past several days. 40 PSI before I ride then 43 PSI when it heats up. However the dash light stays on. Any way to shut it off. I have a new sensor but want to avoid removing the rear wheel if possible.

Have had the opportunity a couple times to dig deep in the controls and push many and varied buttons on TPMS bikes. Never saw a way to disable the warnings. Also find it very unlikely you'd have a way to disable such a safety system. On "light duty" cars it's mandatory since (I think this is right) 2007. So definitely no option there. Just hard to imagine a bike manufacturer accepting the shared liability that would come with making the system elective once it's there.

on my 16 rgu, i have to set rear tire pressure to 42/43 cold or it acts up like your describing, and then when its hot it throw a warning if pressure goes above 50, kind of a PITA but it has saved me one time, started out for a ride and light was on and showed 12 psi and sure enough i had pickup a 3/8 bolt.... tire was junk

What you describe is not an acceptable situation, but there again we are talking about H-D. No TPMS system should force you to overinflate your tires in order to keep the warning light from coming on. If the actual reading matches a known accurate gauge, I'd say the software (BCM) is faulty.

you are correct .... but choose to not let It piss me off, some times we have to pick our battles

FLSTFI Dave · « **Reply #21 on:** July 25, 2020, 06:48:25 AM »

I believe the dealer can set the low value if my memory serves me correct. My 15 had issues, that light was on if under 4 psi. I believe they set the value, if not then they had to install a new sensor as they did fix it.
