FAILED EMISSIONS TEST
Never have your vehicle emission tested if your check engine light is on. If the check engine light is off and your vehicle is newer than 1990, then you should be able to pass the emissions testing. If your check engine light is on and you are do for an emission testing, then call us to schedule an appointment to diagnose the check engine light.
Once we repair the failing component that is causing the check engine light then you should be able to pass emissions testing without any difficulty. However, your vehicle may have to go through its computer processes to determine all is well with your vehicle and that can take time. Make sure you check with us when it is ok to go through emissions testing. Your car’s emissions system not only allows your engine to function properly, but also protects you from the harmful emitted by the engine, such as the exhaust.
The most common problems with the emissions systems are problems with your ERG valve, oxygen sensor or catalytic converter needing repairs. If your vehicle has emission problems, it can also impact vehicle performance and should be taken seriously. A vehicle with a failing exhaust system will fail emissions and consequently be illegal to drive. We have extensive experience fixing emissions related problems and can usually diagnose in a short period of time.
HOW DO I KNOW IF I NEED MY EMISSIONS SYSTEM REPAIRED?
Oddly enough, the first thing to cause a check engine light on most vehicles is the gas cap. The vehicle’s computer monitors the gas tank pressure and a dried-out seal on a gas cap will let out fumes and thus cause a check engine light. Other components we see next are EGR valves, charcoal canisters, catalytic converters, O2 sensors and exhaust leaks.
Signs that you need something emissions related repaired or replaced on your vehicle:
- Rough idle
- Noticeable reduction in engine performance
- Check Engine light on.
- Intermittent stalling.
- Smell of fumes in or outside of vehicle.
CAN I DRIVE WITH EMISSION PROBLEMS?
You should not drive with many emission-related problems. The key is knowing what part is failing and we can advise you if it is ok to drive and for how long. But keep in mind the repair will have to be done in order to pass emissions testing. Driving with malfunctioning emissions systems can be against the law, hazardous to your health and the vehicle’s well-being.
