InnoTechRV TPMS Pressure Sensors

I have the InnoTech Tire Pressure Monitoring System.

Over all I am happy with it. I did have a different one and did not like the display.

The InnoTech display shows the tires and rig as it appears (front at the top and rear at the bottom.



no5 on the display means no sensor.

I have had terrible luck with the sensors.

The caps crack



and when this happens the insides corrode all most instantly.



Up to now Craig has replaced them for free. The unit is now two years old and I will not ask him to replace them for free any more.

I went to purchase some off his site and the pricing does not make sense.

Bulk Buying Options

single $40.00
2 up to 4 $49.00 per item
5 up to 8 $44.00 per item

Has anyone else been having this problem, and if so what did you do about it?

Does anyone have a cheaper source for these sensors?
  • How can you be overall happy with the system and have terrible luck with the sensors? Dump it and search this Forum for `tpms' for more discussion. We have had Pressure Pro for several years.

    The sensors with Lion replaceable batteries
    Tire Minder gives you free batteries, every year, for 7 years. So i simply ever year removed the transmitters when the rig was stored for winter and got new batteries and new O rings. My system was about 4 years old and the thing went crazy alarms and no signal so i gave up on it. Later just to see what would happen decided to contact Minder Research via email.

    1st response "we will give you a small discount on a new system"
    after a few more emails asking why would I consider buying this @#$%$# again when it dies so quickly. For $300 +++ it should be operational for many years

    2nd response - So sorry to hear you have had issues please send the system to us and let us look it over. OK Why not my cost in shipping less than $5.00 so sent it off to Florida.

    Two weeks later after a few probing questions I get a USPS tracking # and a message saying we found your monitor to be defective and new version is on it's way to you. A week or more goes by and a package arrives. A few days later I installed the system and found it works like a champ all at a cost of only $5.00.

    They are good well intentioned folks however the made in China stuff is what it is ...

    Never had any issues with the transmitter caps cracking - do not over tighten them they are cheap plastic nothing more - get the O ring to seal finger tight and you should be good to go


    They are the same unit, just sold under a different name. There are several others out there that are the same units with different names.

    After the first cap cracked, I have only gone finger tight on the cap and then only touched the neraled edge just below the plastic cap on the body of the sensor to tighten the unit onto the valve stem.

    They still crack. I think I have now replaced all the original sensors, the new ones seem to be ok, I hope.

    I've not heard of that brand but if I were you I would dump it as it sounds like you will continue to have problems with cracking sensors. My TST 507 system has been great for about 5 years with zero problems with the sensors. At the time I bought my TPMS system, TST and Pressure Pro were the big players. Both are good companies to deal with. Tireminder gets a lot of good press on this forum too.

    BTW, replacement sensors are expensive from all the companies as far as I know.


    This pricing seems to indicate the sensors get more expensive as you buy more.
