These fumes contain hydrocarbons, carbon monoxide, and oxides of nitrogen, which severely damage our atmosphere and environment and damage air quality, making it difficult to breathe. Thus, it’s vital to make sure your vehicle’s emissions control aligns with state and local regulations. Lockett’s Auto Care offers comprehensive Emission System Repair Services that will help lower pollution while ensuring your vehicle is operating at peak performance.

Understanding Your Emissions System

The emission system is part of the process of keeping your car, truck, or SUV’s engine running cleanly and efficiently no matter the road conditions or weather. Emissions system repair services are usually needed when there is something out of sync. Often this can lead to the Check Engine Light (CEL) coming on. At Lockett’s Auto Care, we offer CEL services, and when it is linked to your emissions system, we can pivot to address that. 

It’s vital not to ignore your CEL. While the problem triggering it may not be an immediate concern, the longer you delay scheduling an appointment for maintenance, the more severe the issue can become. It can also cause other systems to fail or need repair because of strain compensating for the issue. Ignoring emission system issues reduces the gas mileage your vehicle can get (even when a gas/electric hybrid), and acceleration leading to drivability issues.

The Benefits of Our Emission System Repair Services

There are numerous benefits both for yourself and others in having your vehicle’s emissions regularly monitored, such as:

  • Low emissions
  • Performance
  • Fuel economy
  • Longer engine life
  • Prevent premature oil contamination 
  • Compliance with local emission laws 

By maintaining a clean emissions system, your vehicle will release fewer pollutants, which in turn helps keep you and your family healthy. Your car, truck, or SUV shouldn’t be an irritant or cause of respiratory issues like asthma or trigger allergies when the fix is simply maintaining the system already in place to achieve peak performance. Your vehicle runs cleaner and safer for you when you immediately seek out emissions repair services at Lockett’s Auto Care in Catonsville. Our technicians can test your vehicle, ensuring it is running as clean as it can be.

What Our Emission System Repair Services Involves

Emissions and exhaust systems in a vehicle include parts like:

  • Catalytic Converters
  • Valves, gaskets, brackets, clamps, hangers, and flanges
  • Heat shields
  • Insulators
  • Exhaust pipes and tubing
  • Mufflers
  • Fuel injection systems
  • Oxygen sensors

Most modern cars, trucks, and SUVs use a computerized system to oversee the fuel-to-oxygen ratio. This is why our skilled technicians run electrical system diagnostics during our emissions system repair services. Doing so gives us the most accurate information about how your vehicle is operating. 

Several problems can develop in the emission system that can impact your vehicle’s function and cause the CEL to come on: 

  • Faulty vent valve: The purge solenoid is a valve that can become stuck open or closed because of too much or too little flow or a leak in the system.
  • EGR valve: The Exhaust Gas Recirculation (EGR) system reduces the amount of air through the catalytic converter controlling the amount of spent gas that flows back through the intake system. If it gets stuck in the open or closed position, then stalling or rough idling can result.
  • Excessive carbon buildup: Carbon exhaust from the heat and activity of the fuel system and engine can build up in the passages of the exhaust manifold.
