Know theOxygen sensors:

• The Oxygen sensor:Oxygen sensors are a critical component of the fuel and emissions systems because they monitor the amount of oxygen in the exhaust and transmit that information to the engine computer, which adjusts the air-to-fuel ratio accordingly.
• Location:The sensor will always be next to the motor in the engine compartment. It will be on the exhaust pipe leading from the motor toward the back of the vehicle. Most cars these days also have a second sensor behind the catalytic converter, which looks like a metal cylinder on the exhaust line and is found right behind the front wheels.However. Most vehicles made after the year 2000 actually have 4 sensors. Each vehicle has 2 sensors near the motor and 2 near the catalytic converter.

• Signs of a Failing Oxygen Sensor:

  • Check Engine Light Is On:Normally, if your oxygen sensor is malfunctioning, your check engine light will turn on. Instead of ignoring your check engine light, get an inspection from a licensed mechanic as soon as possible. If you drive an older car (10+ years, or above 150,000 km) it is very likely that your check engine light is signalling a faulty oxygen sensor.
  • Increased exhaust emissions:Your oxygen sensor determines the optimal air-to-fuel ratio for your engine by monitoring your emissions in real-time. If your oxygen sensor begins to malfunction, then your engine may be operating at sub-optimal air-to-fuel ratios, which can cause an increase in your exhaust emissions.
  • Bad performance:Your car may misfire or experience hesitation and stalling. Most cars default to the factory air-to-fuel ratio if the oxygen sensor fails, which can cause problems because of non-standard temperature, moisture, or air composition. If your oxygen sensor is failing, then its readings will be inaccurate, again, resulting in a sub-optimal fuel-to-air composition.

  Know how to Replace theOxygen Sensor:

  1. Finding the Error and Securing the Vehicle:

  • Use an OBD code scanner to detect the broken sensor.
  • Let the engine cool before attempting to remove a sensor.
  • Jack up the vehicle if you need to reach a sensor under it.

  2. Removing the Old Sensor:

  • Locate the oxygen sensor underneath the hood or vehicle.
  • Disconnect the electrical connection to the oxygen sensor.
  • Spray some penetrating oil onto the sensor to loosen it.
  • Unscrew the oxygen sensor using a ratchet wrench.

  3. Installing the New Sensor:

  • Select a new oxygen sensor that is the same as the old one.
  • Add a small amount of anti-seize to the new sensor.
  • Turn the sensor clockwise to secure it on the exhaust line.
  • Plug the electrical connector back into the vehicle.
  • Start the car to see if the problem is fixed.

  • Q & A:

    • Q: What is anti-seize?
    • A:New oxygen sensors often come with an anti-seizing or anti-corrosion lubricant that should be applied to the sensor when it's being installed. That will keep the threads on the sensor from seizing, which happens when temperatures fluctuate on the vehicle.
    • Q: How long does it take to replace an O2 sensor?
    • A:It should only take a few minutes depending on your experience level.
    • Q: Do I need to disconnect the battery when changing out the O2 sensor?
    • A:No, there is no need to disconnect the battery when replacing O2 sensors.

    ​

    • Q: Do I need to use a special socket when changing an oxygen sensor?
    • A:It can be done in some cases without a special socket, but normally yes you should have the proper socket.
