Checked my tire pressure while in motion and the rear was 00. First thought was o ****, but no way the tire had zero pressure and I was still riding. Guess the rear sensor has failed and you don't get a low pressure indication when the sensor fails. Almost made it three weeks without going back to shop, but not a big deal for little issues and I live close to a dealer.

 

Well that stinks. I was wondering myself if they gave you a low pressure warning! They should.

 

When mine went out there was a red light that came on and stayed on until the battery was replaced.

 

When my sensor failed I also got a TPMS light.

 

Yes they do. Or at least the 18 does.

 

Strange. I also had a 00 reading on my 2018 Ultra Limited yesterday about 200 miles into a 500 mile trip home. Lasted the rest of the trip. No other warning sign, just saw it while scrolling through the odometer. Today it was back to normal.

 

Mine is also back to normal today. No tpms light or low pressure warning when it read "00".

 

I bought a 21 front wheel without tpms
can I bypass the system
tired of seeing the error light

 

Harley must be have received a bad batch of TPMS sensors. Mine went out right after I finished the 500 mile break-in period. Just had my 1,000 mile service and the sensors are on order.

This sounds like the answer to your problem!
