I installed some TPMS sensors into my after market wheels in February and since the day of installation, the front passenger sensor read 20 Kpa lower than the rest (222 Kpa). Today, I got a warning light saying i have low tire pressure and when i check the dash, it says its at 188Kpa while the rest of the tires are at 240 Kpa. When checking the pressure manually, all 4 tires are aound 34 Psi.

Any ideas?

 

I'm not expert at this.. (been doing my research into the TPMS's though). You said you installed TPMS sensors? what kinds? OEM for 2nd TSX? MDX? generic name brand etc..?

 

They are OEM and apparently came from a RDX.

 

Apparently the RDX ones are not consistently operational with the TSX. Some people have had no problems, while others like you experiences problems. :S ..Im not sure man

 

Sorry to hear about the problem, looks like a malfunctioning sensor.

Try rotate the front passenger tire to the back and back to the front. If problem persist (ie low reading showing on rear tire afterwards), then you need to replace the sensor, otherwise it's the TPMS receiving unit in the front wheel well.
