This is the time when you will need to use a <a href=\"https:\/\/drivinglife.net\/best-automotive-multimeter\/\" target=\"_blank\" rel=\"noopener noreferrer\">multimeter to diagnose the problem.<\/a><\/li>\n\n\n\n<li>Before working, make sure that the engine is cool. It is extremely hot and you will burn yourself if you rush to work.<\/li>\n\n\n\n<li>Look for Bank 2, Sensor 1. Test the sensor. This will provide you with an assurance that the actual source of the problem is the sensor.<\/li>\n\n\n\n<li>Press the tab and pull out. By this time, you should see four wires \u2013 two black, one blue, and one white. Use a multimeter. Connect the multimeter to the prongs connecting to the black wires. If there is no resistance or reading, this is an indication that you have a problem.<\/li>\n\n\n\n<li>Now that you are sure that the oxygen sensor is the issue, it is time to have it replaced with a new one.<\/li>\n<\/ul>\n\n\n\n<p>You are ready to replace your faulty oxygen sensor. To be sure that you are doing it the right way, these are the things that you should do:<\/p>\n\n\n\n<ul class=\"border1\">\n<li>Use an oxygen sensor socket. You do not have to buy a new one. You can rent it from a local mechanic. This is going to make the task a lot easier and quicker to accomplish. The main function is to strip the old sensor and install a new one easily.<\/li>\n\n\n\n<li>Slide the socket into the wire. Once it is in place, use a wrench to remove the old sensor. Screw it all the way until it is completely removed. To be sure, wear thick gloves as the surface can still be hot.<\/li>\n\n\n\n<li>Install the new oxygen sensor. Before you proceed, compare the new one with the old one and make sure that they are the same. You can also remove the old one first, bring it to a car parts store, and ask them to give you the same one. This way, there is a lesser likelihood that you will end up committing a mistake.<\/li>\n\n\n\n<li>Thread the new oxygen sensor in its place. Use the socket to do this. Connect the clip on the other end.<\/li>\n\n\n\n<li>It is important to make sure that the sensor is not too loose, as the gases can escape. On the other hand, if you tighten it too much, the sensor can end up being damaged. <a href=\"https:\/\/drivinglife.net\/best-torque-wrench\/\" target=\"_blank\" rel=\"noopener noreferrer\">Use a torque wrench<\/a> to be sure.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.youtube.com\/watch?v=LPn7CtfZlT0\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Start the engine<\/a> and see if the Check Engine light is still on. If it does not blink anymore, this means that the problem has been successfully fixed.<\/li>\n<\/ul>\n\n\n\n<p>For a visual guide of the steps that have been mentioned above, this short video will help:<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"container-lazyload preview-lazyload container-youtube js-lazyload--not-loaded\"><a href=\"https:\/\/youtu.be\/_Kr-c8eBl5E\" class=\"lazy-load-youtube preview-lazyload preview-youtube\" data-video-title=\"How to Check and Replace an Oxygen Sensor (Air Fuel Ratio Sensor)\" title=\"Play video &quot;How to Check and Replace an Oxygen Sensor (Air Fuel Ratio Sensor)&quot;\" target=\"_blank\" rel=\"noopener\">https:\/\/youtu.be\/_Kr-c8eBl5E<\/a><noscript>Video can&#8217;t be loaded because JavaScript is disabled: <a href=\"https:\/\/youtu.be\/_Kr-c8eBl5E\" title=\"How to Check and Replace an Oxygen Sensor (Air Fuel Ratio Sensor)\" target=\"_blank\" rel=\"noopener\">How to Check and Replace an Oxygen Sensor (Air Fuel Ratio Sensor) (https:\/\/youtu.be\/_Kr-c8eBl5E)<\/a><\/noscript><\/div>\n<\/div><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tab-con-3\">Pro Tips<\/h2>\n\n\n\n<p>To guarantee the best outcomes, here are some of the tips that you have to keep in mind:<\/p>\n\n\n\n<ul class=\"border1\">\n<li>A quick visual inspection will already give you an idea that an oxygen sensor is damaged. Usually, the color should be light tan. If it is light gray, black, or white, this can be a sign that there is a need for a replacement. Nonetheless, you should still proceed with the testing to be sure.<\/li>\n\n\n\n<li>It is important that you protect your hands by wearing gloves, as noted in the steps I have mentioned above. You should also be careful with the probes. See to it that their tips won\u2019t end up touching the exhaust pipe or the exhaust manifold because its extreme heat can damage the probes.<\/li>\n\n\n\n<li>The oxygen sensor can be extremely fragile. For this reason, you need to handle it with extreme caution. The tip should not get in contact with anything as it can end up being contaminated. It is made from a special type of ceramic, so you have to be extra cautious.<\/li>\n\n\n\n<li>Always consult with the manual from the manufacturer. The appearance of oxygen sensors may differ depending on the car that you have, so that means there can be different approaches to how things should be done.<\/li>\n\n\n\n<li>Do not use oils and sprays to clean the oxygen sensors. They contain contaminants that will have a negative effect on the performance and function of the sensors.<\/li>\n\n\n\n<li>Generally speaking, oxygen sensors do not need care and maintenance. Once they become faulty, they can no longer be saved. Instead, the best thing to do is to have them replaced.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tab-con-4\">Conclusion<\/h2>\n\n\n\n<p>Knowing how to check and replace an oxygen sensor is vital for every car enthusiast, which can also help you save a lot of money in the long run.
