Signs Your Vehicle Has an Emissions Problem
Every two years, Connecticut requires all drivers to have their vehicles undergo an emissions test. While it might come as a surprise if your car doesn’t pass, there are often warning signs that indicate a potential issue with the emissions system.
The vehicle’s emissions system is designed to reduce the amount of harmful pollutants released into the air. In addition to protecting the environment, it also helps improve fuel efficiency and ensures the engine runs smoothly. The system includes components like the fuel tank, carburetor, exhaust system, and crankcase. Most modern vehicles also feature an Evaporative Emission Control (EVAP) system, which captures and burns off harmful vapors before they escape into the atmosphere. Key parts of the EVAP system include:
- A vapor recirculation tube
- A vapor control valve
- An evaporative emission canister
- A fuel tank pressure sensor
- A canister vent valve
- A purge valve for the evaporative canister
- A two-way evaporative valve
Controlling emissions not only benefits the environment but also contributes to better public health by reducing air pollution. Ignoring emissions issues can lead to higher rates of respiratory problems, such as asthma, and even carbon monoxide poisoning in affected areas.
If you're experiencing any of the following signs, it could be a sign of an emissions problem:
**Check Engine Light**
While this light isn't very specific, it often indicates an issue with the emissions system. It could signal a faulty sensor, a leak, or other problems that allow harmful gases to escape.
**Decreased Performance**
A failing emissions system can affect how your car runs. You may notice reduced power or poor acceleration, especially if the system is interfering with the engine or exhaust.
**Poor Fuel Economy**
An inefficient emissions system can cause your car to use more gas than usual. If you’re burning through fuel faster or getting fewer miles per gallon, it might be due to a leak in the system—such as in the carburetor, muffler, or fuel tank.
**Unusual Odors**
A strong smell coming from the exhaust, especially a gasoline-like odor, could mean there's a fuel leak. This is not only a sign of an emissions problem but also a safety hazard.
**Fuel Tank Leaks**
If the EVAP canister becomes clogged or damaged, it can cause the fuel tank to lose pressure, leading to leaks. This can affect the entire emissions system and lead to failure during testing.
