Title: TMPS
Post by: George Frudakis on March 27, 2022, 04:40:53 PM

I have Tmps 507 flow-through the sensor system and it is time to change batteries. No problem completed that, but when I install the sensor on the inside tires both will not allow me to air up. I have extention for easy access. Any idea what is causing the problem.

You need to adjust the schrader valve on the end of your extensions. Get a tire valve tool and unscrew the schrader valve on the extension a bit. The flow thru sensor has to depress the schrader valve on the extension so you can air up or read the air pressure on the tpms.
