We inspect your car or truck's emissions-control equipment to measure the number of pollutants your vehicle is emitting.

First, J-Town Auto will analyze your car or truck's OBD computer system, emissions-control system, and check engine light codes for standard warnings that your emissions system is no longer functioning properly.

Next, J-Town Auto will inspect your car or truck's gas cap, ignition timing, exhaust gas recirculation system, fuel, and evaporative system.

Finally, J-Town Auto will perform a Tailpipe Emissions Inspection which measures the type and quantity of any pollutant emitted from your vehicle's tailpipe.
