Hi everyone. Steven here with etrailer.com. Let's take a look at our replacement SE-2 cap sensor for the TST 507 Series TPMS System. So folks, this replaces one, quantity one, of your SE-2 cap sensor for that TST 507 Series TPMS, or tire pressure monitoring system. It works with all those TST 507 Series systems, and both metal and rubber valve stems. If you don't already know, you simply screw this in place of the factory valve stem cap, and you're good to go with the rest of the sensor system.
Well, that's gonna wrap it up folks, for our quick look today. I'm Steven. Thanks for watching.
Works great. I did have to contact support to get one of my sensors to show up on the display again. But once I tried the Go and + they recommended, this sensor shows up and all is good again. I recommend getting additional ORings. I wish they sold them in packages with 2 extra. They break easily when replacing them.
I received tech support from TST, looked for best price for the product and chose etrailer.com. The item, TPMS sensor for our spare tire on our RV, came in on time and it is just right for my application. The installation will be easier than I expected.
These were to replace older sensor and monitor. Took some doing but was able to get all the old sensors to work with the new monitor. Found out the old cap sensor was good but the tire valve was bad. Tire leaked air when driven with the cap sensor. Once tire valve was replaced, it worked as advertised. Thank you for helping me with this purchase.
My order was filled and shipped quick.
Not compatible with lippert tire link.
Will try to return
Monitor was received on the date and day as said via USPS. I have not put said CAP SENSOR Monitor for TST 507 series on the tire at this point, though I did check see if it it would actually fit and it does. Placement of said sensor on tire for travel will take place in the next few days but it does appear to be what was definitely needed as a replacement. Thank You Very Much.
Prices right, service outstanding!
Etrailer always quick and responsive
Great service
This was a replacement for a damaged sensor on on car. Easy to install and works well.
This sensor was easy to mate with the temperature/pressure TST monitor. I use the TPMS on my utility trailer tires.
'Replacement for one that got lost...works perfectly! Thanks Madison
These sensors work well and are easy to setup. Delivery was quick and without issue.
