Every vehicle is equipped with specific emissions technology to help keep it from polluting the environment with gaseous fumes. When your vehicle doesn’t pass its emissions test, a host of problems could be happening with your engine and its associated components that require you to have engine repair in Conway, AR. Here are the most common reasons for emissions failure and what you can do about it:
- Defective oxygen sensor: When your vehicle fails to meet emissions requirements, a faulty oxygen sensor may be to blame. The oxygen sensor is used to monitor how much oxygen is present in your exhaust system. While this will cause you to fail an emissions test, it can also lead to problems such as overheating and loss of power in your car. Have an auto shop diagnose your vehicle for this fault and provide engine repair in Conway, AR to replace your oxygen sensor if necessary.
- Vacuum leaks: This also involves a sensor in your engine and would require engine repair in Conway, AR if it is not working properly. This sensor works in conjunction with the engine’s electronic control system to measure load. Leaks in the gaskets or vacuum lines can affect this sensor’s ability to work correctly and can cause you to fail an emissions test. An auto repair shop will be able to identify whether you have a vacuum leak that is affecting your vehicle’s emissions.
- Malfunction of the EVAP: Your evaporative emission control system (EVAP) is specifically designed to prevent the vapors from the fuel system and fuel tank from being released and harming the environment. When you have a leak in the vacuum hose, vents, valve or a faulty gas cap, these gaseous vapors can escape into the air. If your vehicle is leaking fuel vapors, it will not pass its emissions test and will have to have repairs to get your EVAP system functioning again.
- Faulty air injection system: Your air injection system is vital to the operation of your engine. It reduces the hydrocarbons and carbon monoxide produced by your engine’s exhaust system. If your air injection system is failing to reduce the amount of emissions your vehicle’s engine produces, it will cause your vehicle to fail the emissions test and will require engine repair in Conway, AR to get it working again. Visit your auto shop for an inspection to identify whether the air injection system is to blame for your emissions test failure.
