Computer Diagnostics

Is your check engine light on? Our ASE certified mechanics at Old Town Car Care in Pleasanton, CA can help! We have the tools and experience to diagnose your vehicle. A check engine light might indicate anything from a loosened gasoline cap to something much more serious like a blown head gasket. Having issues checked as soon as possible may stop additional failings of engine components.


Most vehicles now are furnished with advanced digital engine monitoring systems which can find and even prevent problems which will hurt your car. The computer system in your engine gets details from a collection of sensors and switches which informs your ignition, fuel systems and emission control systems what to do. When any of those systems fail or misfire, it triggers the computer system to turn on your check engine light.


Call us at the first sign of any sort of engine complications such as:

  • Noises and knocks

  • Low fuel economy

  • Failing to pass an emissions examination

  • Dash panel caution lights


We can diagnose issues in your engine by tapping into your car's computer system:

  • Anti-lock Brake System (ABS)

  • Ignition System

  • Electrical Systems

  • Emissions

  • Fuel Injection System

  • Obstruction Systems

  • Loose or worn out hoses

  • Sensors and Spark Plugs
