* Low tire pressure. This is the most common cause of the low trac light coming on. When your tires are low on pressure, they can't grip the road as well, which can cause the traction control system to engage.
* Worn brake pads. Worn brake pads can also cause the low trac light to come on. When your brake pads are worn, they can't create as much friction, which can cause the wheels to slip and the traction control system to engage.
* Faulty wheel speed sensor. A faulty wheel speed sensor can also cause the low trac light to come on. The wheel speed sensors monitor the speed of each wheel, and if one of the sensors is faulty, it can send an incorrect signal to the traction control system, causing it to engage.
* Faulty traction control module. The traction control module is the computer that controls the traction control system. If the traction control module is faulty, it can cause the low trac light to come on even if there is no problem with the tires, brakes, or wheel speed sensors.
If the low trac light comes on in your Pontiac Firebird, it's important to have it diagnosed by a qualified mechanic as soon as possible. Driving with the low trac light on can be dangerous, as the traction control system may not be able to engage when you need it.
