Purchased After-market (Cheap) TPMS off of Ebay

Recently, I received an after-market Tire Pressure Management System ("TPMS") off of ebay for about $20. The ebay Seller described the TPMS as "Wireless Solar TPMS LCD Car Tire Pressure Monitoring System + 4 External Sensors". The seller's handle is uronlifestore. Purchased it on ebay and received in less than a week. The TPMS has the following items:

1.) Head unit display which has solar and usb charger;
2.) Four ("4") wireless external sensors which screw onto the valve stem in lieu of the dust cap; and
3.) Four ("4") locknuts for external sensors and wrench.

Got this TPMS going today and yesterday. Directions were not very helpful. Instead, I watched a YT video which pretty much laid out the various issues in setting this up. So far I have set up tire pressure to be presented in PSI (rather than bars) and I have also set up tire temperature to be set up in F. I still have to do the following: i.) figure out how to set low pressure threshold; ii.) figure out how to set high pressure threshold; and iii.) figure out a permanent mount for this unit (temporarily this unit is beneath the radio in the little storage area (with fold-down door).

Just thought that I would share. Last I checked my air pressure (and filled tires) was about four weeks ago. Found out that my RR tire was low on pressure (but did not look low). So I filled RR with some more air (I will keep on eye on that one as I may have a slow leak - 40psi to 25psi in four weeks).

 

I have attached pics of the 4 page instruction manual. IRL, the 4 page manual is printed on both sides of a 3"x3" piece of paper.

 

I agree a phone app would be especially sweet. I wonder if the Torque app could handle the wireless signals from the external sensors?

 

No calibration for sensors needed. However, I did check the readout on the screen and then remove each sensor temporarily so that I could compare to my tire pressure gauge. IOW, no initial calibration but subsequently checked for accuracy with manual gauge (all accurate within one PSI). TPMS came with sensors paired to the head-unit-display.

 

Thanks for the heads-up. I will apply some never seize* and that should prevent a problem.

Duplicate posting. Whoops!!!!

 

Is the bottom right picture (4th pic) a pic of the phone app reading the Toyota sensors?

If so what phone app?

 

Just got back from the tire shop. My RR tire was losing about 5 to 6 psi per week as shown by my cheap-aftermarket-TPMS system. Filled the RR tire up with air after first week and same thing happened the 2nd week. Today, the tire shop found a very small nail in the tread (of the offending RR tire) which you could not see with your eye. Tire shop was able to find the leak by immersing the tire in the water tank.
