Front right tire indicates 33psi even after multiple trips in the car, the sensor says low? Same pressure as drivers side and that has no issue. Tpms sensor problem? Tire looks good but haven’t actually checked it’s pressure outside of the tpms reading.
I’m guessing it went past the alert trigger and the others didn’t, so when you drove and tires inflated a bit the original alert will still be there until you pump it back to the recommended spec, which is 35 psi
