I just got a really good deal on a 2013 Nissan Sentra SL that was slightly used (1k miles). After a little closer inspection I am pretty sure that the dealer swapped the alloy SL wheels with the steel S/SV wheels. The TPMS light was on when we bought it and I assumed maybe the tires were just low. Assuming all the sensors are still in place, is this just a trip to the dealer to reset the TPMS?
