Research on Oxygen Sensor for Ford Focus

Every car's oxygen sensor measures the unburned oxygen in the exhaust as it exits the engine. The 2012 Ford Focus o2 sensor location is in the exhaust manifold. The reason for the measure is to gauge the fuel mixture and see if it is burning rich or lean. This information is sent to your vehicles computer and is used to help your car run efficiently and to reduce emissions. If you see your check engine light come on, you could be having Ford Focus o2 sensor problems. If your car has Ford Focus o2 sensor bank 1 sensor 1 problems then it may have a poor idle, a problem starting, and high fuel consumption.

Start with the Upstream First

Is it necessary to change both upstream and downstream oxygen sensors? The upstream o2 sensor controls the engine while the downstream one measures the catalytic converter operation. Starting with the upstream o2 sensor is usually the best option to see if that fixes the problem. The best tool to use to remove the o2 sensor once you have found the 2006 Ford Focus o2 sensor location is called an oxygen sensor socket. Simply using this tool and changing your oxygen sensor can help you pass your emissions test.

Bad Smell

If there is a rotten egg odor coming from the exhaust or your check engine light is on in your Ford Focus this can be an indication of a bad oxygen sensor. In this situation, you need to do a 2013 Ford Focus o2 sensor replacement. The problem with a bad oxygen sensor is that you get the wrong mix of gasoline and oxygen which can increase the pollutants flowing through your exhaust. If this happens the mixture can prematurely cause your catalytic converter to fail or even worse, damage your engine. A failed catalytic converter can be an expensive repair, especially on any car. It is important to get this addressed as soon as possible. An important point is that intake and exhaust leaks can trigger problems in your oxygen sensors. If this is the case, a problem code may show but there may be nothing wrong with the oxygen sensor. Simply fixing any leaks can resolve the situation with your oxygen sensors and give you the performance you expect from your Focus.

Fix Fast

Having a local repair shop change your oxygen sensors will cost $125-$360 for only one and almost half of that is for labor. Going to the dealership can cost a lot more. With the proper sensor socket, you can do the job yourself quickly. A faulty oxygen sensor is a primary reason that vehicles fail the emissions test at inspection stations. It is important to fix. All you need is a little time. If you have a Ford Focus oxygen sensor problem, you can save money on your Ford Focus oxygen sensor bank 1 sensor 1 and your 2005 Ford Focus oxygen sensor at PartsGeek.com. We sell parts and accessories exclusively online. We don't have a big building and a big overhead. This translates into better prices for you.
