I have purchased TPM sensor FXTH8705116T1- 450kpa.
I have installed it inside Tire and filled with an air pressure of 42 PSI.
The pressure value received from the sensor is 0x1FE (TPMS_COMP_PRESSURE).
From the data sheet, 0x1FE (TPMS_COMP_PRESSURE) represents pressure overflow(high). But 450kpa sensor has a range of 14 - 65 psi(100 – 450kpa).
Also when we gradually reduced the air level from tire, sensor pressure value also decreased gradually from 0x1FE (0x1EA , 0x1Ab etc.,).
For 42 psi , expected pressure value from the sensor should be around 0x122. But receiving 0x1FE. Please help.
