tpms repeater

I have a 34' 5er with TST 507. Most of time all sensors register. But occasionally one would drop out. So I added a repeater.

We have the TST 507 system also. The sensor for #1 axle right side of 5 ver was not working. 2 year old system. I had trouble finding 1632 batteries in socal. When I got home I pulled the sensors and all batteries read approx 3 volts except the bad sensor read .9 volts. Replaced all batteries and all is great again. BTW 1632 Duracell batts at Safeway were $5.99 each. Ordered 8 online to carry for next time.

I also have the TST 507 on a 32' 5er and would lose a couple of sensors intermittently, a repeater from TST mounted in front storage compartment near the battery box solved that problem. :)

I also have the 507 with a 33 ft. 5th wheel. I installed the repeater because mine would lose all the sensors at times particularly when in an urban area. The repeater solved that problem. If you aren't getting the same signal all the time I would think it is something else. You might try changing the sensors to a different position and see I that makes a change.

Had the same problem check your valve stems some are screwed in to far. The sensor has to push on the valve stem in order to get a pressure reading some times just backing out the stem out a turn or half turn will do.

I have the same system. I have a 42 Ft unit and do not need a repeater. Perhaps a battery change would help? I would try that before I would purchase a repeater.

Repeaters or boosters for TPMS systems are brand and model specific. Contact TST to find out about yours.
