Check Engine Light Diagnostics in Londonderry, New Hampshire
Professional Diagnostics and Repairs
There It Is—The Illuminated Light
You’re driving along, and there it is–the illuminated check engine light. While no driver wants to see a dashboard warning come on, this one is usually not an emergency. You should seek prompt attention for your car, but you can keep operating the vehicle to reach our facility. (Note: This state applies if the light is steady and solid. If it’s flashing, stop driving and have your automobile towed to our shop because there’s a serious problem that may cause extensive damage if you continue driving.) Once you’re here, one of the ASE certified technicians Tires Too in Londonderry, New Hampshire, will accurately diagnose the problem. We’ll connect our up-to-date technological equipment to your auto’s OBD-II port to obtain a trouble code, and use our expertise and experience to narrow down the category to the specific trigger. You’ll find us nearby at 1A Rockingham Rd Unit 8, Londonderry, NH 03053, convenient to your work and/or home. Make your appointment for check engine light diagnostics by using our online scheduler or calling (603) 434-2730.

Related Services Your Automobile Might Need
Even though the check engine light shouldn’t incite panic, the sooner you get attention for your vehicle, the better. Getting assistance with the related services your transportation might need to correct the underlying cause will keep your car from compounding additional problems. It will also help you ensure that your vehicle can pass the annual required New Hampshire inspection. What’s more, timely repairs will likely remedy some issues you may be noticing such as misfiring, rough idling, difficult starts, reduced power, and poor fuel economy. Once our expert mechanics identify the exact CEL trigger, we’ll work with you to plan corrective action. This may be as simple as tightening or replacing a loose gas cap, or your car may need more extensive service. For example, a bad mass airflow sensor (MAF) or oxygen sensor (O2) can cause your automobile to operate poorly and waste fuel. Both these sensors detect levels (either intake or exhaust output) that direct your vehicle’s computer components on what’s needed to optimize performance. Also, poorly working emissions system components such as the catalytic converter, EGR valve, or PCV valve may need replacing so that your auto works well and the light will stop glowing. Finally, a vacuum leak can also trigger poor operation, the check engine warning, and even limp mode (caused when your car’s engine control unit or ECU slows the auto to crawl to protect itself). Fixing the breach in the vacuum will effectively repair the check engine light.
Turning Off the Malfunction Indicator Lamp (MIL)
Obviously, you’re going to need assistance turning off the malfunction indicator. However, you won’t have to worry if you bring your vehicle to Tires Too. Opening in 1988, we were in business before the modern (second generation, OBD-II) check engine light with universal codes was even mandated (which occurred in 1996). Thus, we’ve been performing check engine light diagnostics and related repair services since the very beginning. This gives us the experience needed to correct problems and keep your car going strong.
