How To Repair An Oxygen Sensor Correctly!

Hi-ya! good night, at this moment we will write an article about How To Repair An Oxygen Sensor Correctly!

Oxygen sensors are small devices in your car or truck that measure and balance the oxygen/fuel ratio. As a member of the emissions control system, the oxygen sensor carries information to your car’s power control module, which is the brain of the vehicle’s computer. If you have problems with the O2 sensor or lambda probe, continue reading and learn how to repair oxygen sensor correctly.

Typically these types of sensors are mounted in the vicinity of the exhaust pipe on each side of the catalytic converter and over time can become clogged and stop working. When this happens, it can cause your car to break down unexpectedly. You can repair your oxygen sensor to get a few extra miles out of it, but ultimately you’ll have to replace the lambda probe.

The steps you must follow to to fix the oxygen sensor or a lambda probe of the car are the following:

  1. Find out which sensor is damaged. You can take the car to any auto parts store and have them run a free diagnostic test that will show you which sensor is failing and where.
  1. Raise your car and put the jack legs in place under the frame.
  1. Locate and remove the oxygen sensor. Your car’s oxygen sensors are usually on the passenger side and are neatly mounted on the exhaust pipe on either side of the catalytic converter. Remove the lambda probe by loosening the retaining bolt screws with a socket set and then disconnecting it from its electronic wiring harness.
  1. Gently clean the end of the probe in the form of a metal tube with the help of a wire brush in order to eradicate all dirt. Use a can of compressed air to spray it down and clean it up even more.
  1. Pour some gasoline into a plastic tank. Place the half of the sensor in the form of a metal tube in the container with the fuel. Let it sit in the gasoline overnight.
  1. Take off the lambda probe or sensor the next day and clean it with a towel.

Reinstall the lambda sensor or oxygen sensor in your car by first positioning it in its area and locating the retaining bolts in their designated location and tightening with the socket set. Plug the electrical wire harness back into the back area of ​​the sensor and eventually this should allow you to get more miles out of the sensor before having to completely replace it.
