What is an O2 sensor?
An O2 sensor, also known as an oxygen sensor, is part of your vehicle's exhaust system. The sensor monitors the amount of oxygen that is in your vehicle's engine as it burns the fuel that exits through your vehicle's exhaust pipe. As you may know, your vehicle's engine contains an oxygen and fuel mixture that, if present in the correct ratios, ensures the best fuel economy for your vehicle. We at Downtown Automotive in Nelson can go over these ratios with you if you'd like. If there is too much or too little oxygen in your vehicle's engine, the oxygen sensor will send a signal to the engine's computer and more or less fuel will enter the engine to restore the correct ratio.
It is important that your o2 sensor is working properly to prevent engine damage and damage to the catalytic converter as well as to keep your vehicle's emissions systems in check; if the ratio of fuel to air is not ideal, it will compromise the fuel economy of your vehicle. Downtown Automotive has performed hundreds of o2 sensor services for residents of Salmo, BC, Trail, BC, Nelson, BC, Balfour, BC, Castlegar, BC, and beyond, so you can trust us with your vehicle. In general, newer oxygen sensors can last for up to 100,000 miles or more if it is maintained regularly. We at Downtown Automotive will take a look at your o2 sensors as part of your vehicle's maintenance.
How do I know if my vehicle needs an O2 sensor replacement?
It is imperative to note that although it may appear that your vehicle needs an oxygen sensor service, the real problem may be faulty spark plugs. If the spark plugs in your vehicle are misfiring, there will be excess oxygen in your vehicle's engine because the spark plugs are not sending fuel to the engine. Our technicians at Downtown Automotive will check for that issue when you bring your vehicle in.
Whether you drive a Honda, Subaru, Chevrolet, Nissan or any other vehicle, the signs of a faulty o2 sensor are universal. In most cases, your o2 sensor can be repaired. However, you may need a sensor replacement if the oxygen sensor fails. We at Downtown Automotive in Nelson can guide you through what your vehicle needs. Here are some warning signs that your o2 sensor needs repairs or a sensor replacement:
- Your check engine light turns on: This light could turn on for a variety of reasons, and we at Downtown Automotive can give you an exact diagnosis. However, if your check engine light turns on and you are experiencing the following symptoms, your vehicle probably needs an o2 sensor service.
- You are getting fewer miles per gallon: If the o2 control systems are not working properly, the fuel-to-air ratio will be thrown off and will compromise the efficiency of your vehicle. Not only will you end up spending more money on gas and your vehicle will have a more negative environmental impact if you do not get this issue resolved, you also run the risk of not passing a vehicle emissions test when the time comes.
- Your engine misfires and/or you experience a rough engine idle: Because the o2 sensor controls engine timing and the all-important fuel to air ratio, a bad sensor can disrupt these engine functions
