Aftermarket TPMS display

There's lots to choose from on Ebay and elsewhere in the $15-$30 range... Basically the valve caps measure the pressure and send a signal to a display that has a battery in it. There's more elaborate ones than that, but that's where it starts.

 

this thread has some ideas:

I'm running this in my Tacoma, in wheel TPMS has been dead for several years. Very simple system, install the pre programmed valve caps and go for a drive in about 5 minutes to initialize and it will show the updated tire pressure and temperatures. Has a solar panel so you don't need to charge it often also it powers down on its own I think the unit is activated by sound or has an accelerometer, when I open the door it powers up automatically. You can also change the batteries in each of the sensors.

I think they run about 60-70 on Amazon. This one was a gift.

Define "cheap".

If your TPMS works, then you could get a capable scantool and read the tire pressure data from the car's ecu. It's a bit more fiddly than having a separate dedicated display but it's an option to consider.
