Check Engine Light Diagnosis & Repair

Some Of The Automotive Maintenance, Repairs & Services We Offer

Vehicles made in today’s day and age are fitted with intricate computer systems that connect everything to one another.  The computers on-board the vehicle constantly read and write info regarding the performance of your vehicle, in real time.  When you see a warning light flip on, it’s due to the computers in your vehicle catching a component in your vehicle not performing as intended.  This could be anything from making sure your gas cap is tightly sealed, to your braking system failing.  While some lights can be ignored for a time before resolving the issue, others can prove to be a danger to leave unintended.  If you’re unsure of what the warning light in your vehicle is trying to tell you, come down to K & M Auto.  We provide check engine light diagnosis & repair services for all vehicles.

K&M Auto provides top-class check engine light diagnosis & repair services with our team of professionally trained and certified mechanics.  Our team is highly experienced in check engine light diagnosis services; and we have the equipment and knowledge to effectively diagnose and repair the abnormality in your vehicle.  At K&M, our highest priority is ensuring our clients’ vehicles are safe and ready for the road, and our clients’ utmost satisfaction in our services.

When you bring your vehicle in, we will also change the oil, rotate your tires, replace belts or hoses, inspect your brakes and make any other repairs that are necessary. We will replace air filters, spark plugs and any other parts that are dirty or worn-down. Basically, we will comb over your entire vehicle looking for faulty parts or potential issues that could lead to more expensive problems down the road.

With a K & M Auto Service oil change, or any other service, you’ll receive a Touch® Courtesy Check. We’ll look inside, outside, under the hood and underneath the car, then explain the findings and give you a written report.

While you’re there, let us perform a Touch® Courtesy Check, which includes a visual check of the following items:

  • Engine air filter
  • Brake fluid
  • Power steering fluid
  • Automatic transmission fluid
  • Coolant/antifreeze
  • We’ll also walk you through your vehicle manufacturer’s recommendations for replacing these vital fluids and filters.
