American Tire and Service
Serving Rio Rancho, Sandoval and Bernalillo Counties
The engines in today’s modern vehicles are highly sophisticated pieces of equipment. Due to the Federal Exhaust Emission and Fuel Economy regulations, today’s new vehicles use electronic engine control systems that help to curb carbon emissions and also increase fuel efficiency. Since the advanced control systems now the place of simple engine components, some common maintenance services such as tune-ups become less vital. However, your vehicle still requires regular services (such as spark plug and filter replacements), and it’s a good idea to have regular computerized analysis of your vehicle’s control computer. Our factory-trained technicians provide these basic services.
Here’s how your modern vehicle’s control computer operates:
A network of sensors and switches convert and monitor your engine’s operating conditions as they produce electrical signals. The computer receives this information, and, based on information and instructions coded within the complex computer program, it sends commands to three different systems: ignition, fuel, and emission control. If a problem arises—the “check engine” light turns on—which is your indication to schedule an appointment to have our service professionals check the vehicle. The “check engine” light may indicate a real problem, or it could just be a sensor/computer issue that needs a quick reset.
Here’s a brief overview of your vehicle’s sensory components:
- Mass airflow sensor
- Throttle position sensor
- Manifold absolute pressure sensor
- Coolant temperature sensor
- Exhaust oxygen sensor
- Crankshaft position sensor
- Camshaft position sensor
