TPMS affect gas mileage?
My daughters 2008 Avenger with the I-4, 106K on it. The gas mileage is around 16 MPG. The TPMS light has been on for a month or so. The pressures are OK but, between school/work, she hasn't taken the car to have the sensors checked. We know the the light being on is creating some issues with the remote entry. Does it play havoc with gas mileage also ?? From what I can see the air filter and spark plugs are the only tune-up. Am I missing something ??
Thanks in advance
