Vehicle Emissions

Automotive vehicles produce harmful emissions, which are handled by the vehicle emissions system. Otherwise known as exhaust and emissions, the vehicle emissions system reduces harmful fuel emissions, while supressing engine noise. The exhaust and emissions system includes five components:


  • Catalytic Converter

    Function - reduces the exhaust system's harmful emissions.

    Signs of Wear - reduced engine performance and bad gas mileage, increased exhaust emissions.


  • Muffler

    Function - reduces exhaust noise.

    Signs of Wear - loud exhaust

  • PCV Valve

    Function - controls internal pressure in the engine.

    Signs of Wear - engine is stalling, rough running engine.

  • EGR Valve

    Function - recirculates some of the engine's exhaust gas back into the intake manifold to be reburned, thereby reducing emissions.

    Signs of Wear - rough running engine, engine is stalling, service engine light is on.

  • Oxygen Sensor

    Function - senses oxygen content in the exhaust gas. The Powertrain Control Module uses this input to optimize the combustion process.

    Signs of Wear - rough running engine, bad gas mileage, service engine light is on.

The Exhaust and Emissions system is best left to the professionals at Wheatland Automotive. Submit your car for an exhaust and car emissions check at least once a year to prevent complications.



We work on all of the above. Plus, we can help you prevent future brake-related issues. Do not drive with underperforming brakes; it is not worth the risk. With the failure of just one vehicle brake your vehicle braking system becomes flawed. Vehicle brakes, in unsuitable conditions, can threaten your safety, especially in bad weather conditions. Brake problems often result in fluid leaks, but they are more commonly identified by a car brake squeal.


Service and Maintenance

Maintain your vehicle emissions system:

Maintaining your vehichle's exhaust and emissions system is best left to the professionals at Wheatland Automotive, because of the complexity of vehicle computer systems.
Inspect positive crankscase.
Often, check brake lines for rust, punctures or leaks.

For best results, bring your vehicle into Wheatland Automotive for a thorough inspection by a qualified technician.
