The service tire monitor light on a 2005 Chevy Tahoe means that there is usually a problem with one of Your tire pressure monitoring sensors. The sensors can fail over time and You may need to replace them. The sensors are an important part of Your vehicle's safety system because they can let You know when Your tire pressures are too low. This can help You in the event of a puncture or a blow out to know that there is a problem with one of Your tires before it becomes dangerous to drive on. On average replacing a tire pressure monitoring sensor should cost $75 per wheel when done at a dealership.
