4 Common Reasons a Car Will Fail an Emissions Test
Nearly every personal vehicle must go through smog and emissions testing to be legally registered. If you have ever failed an emissions test you know that it is a stressful situation, as it generally requires a trip to the mechanic. Fortunately, some of the most common issues related to emissions test failure are actually quite inexpensive to repair. It is important to have these problems corrected, not only because you'll need to in order to keep your car legal, but to ensure it is running at maximum efficiency. These are 4 of the most common reasons a car will fail an emissions test.
Bad O2 Sensor
If your oxygen sensor malfunctions it can not properly monitor the exhaust and may cause additional problems such as overheating, loss of engine power or poor acceleration. However, what is important to the licensing department is that it can also increase the toxicity of your emissions.
Rich Fuel Mixture
When monitoring the emissions of your vehicle it may be found that there are high levels of carbon monoxide, which occurs if your vehicle is burning excessive amounts of gasoline. This can happen because of a faulty MAF sensor or oxygen sensor or because of leaking fuel injectors.
Bad Fuel Metering
Your vehicle monitors fuel use to ensure that there is a proper air-fuel mixture for a smooth running engine. If the computerized engine control or fuel injection unit fails or malfunctions the monitoring will be out of specification.
Faulty EVAP System
The Evaporative Emission Control System, also known as EVAP, prevents the release of gasoline vapors into the atmosphere. This system can malfunction if there is a leak in the connected vacuum hoses or vents, or even if there is a broken, loose or cracked gas cap.
