Can I drive with a faulty occupant sensor?

A faulty occupant sensor may cause the passenger airbag to be disabled. While the vehicle is still drivable, the passenger airbag will not deploy in a crash. Have it repaired promptly.

Why is my fuel gauge reading incorrectly?

The most common cause is a failing fuel level sending unit inside the fuel tank. The float or resistor can wear out, causing erratic or stuck readings. Replacement costs $200-$500 including labor.
