TPMS issue--maybe
I was driving on the highway running around 75mph when my dash went off “Service tire pressure monitor”, light was blinking then stayed on. The left rear showed (XX PSI) I got off the highway and drove on the back roads to go home, when the left rear went to reading again. Well the next day was driving on the highway again, this time the left front and right rear did the same thing (XX PSI). Then the right front went to (XX PIS) and the right rear went to reading. Got home looked at everything, nothing. My wheels were really dirty on the inside, so I cleaned them (needed too) but figured no way this could be the issue. Drove to my friend house (on the highway) running around 80mph, nothing, everything was normal. Was this self-induced or do you think I still have a problem?
DIC three separate times for my left front tire. The tire pressure on the DIC also reads low. On checking the tire it is fine, so I'm wondering if the tpms sensor is going bad or what?
