The Mackert Automotive Guide To Vehicle Diagnosis

Why is my check engine light on?

Modern Gig Harbor vehicles have several computers on board that control all kinds of things like engine functions, transmission shifts, traction control, anti-lock brakes, stability control, emissions - and on some vehicles, even steering, braking and the throttle.

Think about that for a minute - things that used to be controlled by simple mechanical connections now have electronic controls that rely on computers, software and sensors. It's no wonder that when something goes wrong with their car it can be pretty complicated for Gig Harbor drivers to track down the source of the problem.

To help your Mackert Automotive service advisor figure out what's wrong, your car is equipped with on-board diagnostics. The Check Engine Light comes on to tell you there's a problem and the engine management computer stores a trouble code. Your friendly and courteous Mackert Automotive technician connects a scan tool to your vehicle's diagnostic port and retrieves the trouble codes as well as other important data.

Trouble codes are like clues for the Port Orchard technician to follow as he diagnoses what's wrong with your car. In a way, it's like going to your Gig Harbor doctor with a problem. She'll run some additional tests and gather the information she needs to make a diagnosis and form a treatment plan. How much a vehicle diagnosiscosts at Mackert Automotive in Gig Harbor depends on how much time it takes to sort out the symptoms and find the underlying problem.
