How do you change o2 sensor on 2000 Acura integra?

Answer 1

Caution: The sensors use a pigtail and connector. This pigtail should not be removed from the sensor. Damage or removal of the pigtail or connector could affect proper operation of the oxygen sensor. Keep the electrical connector and louvered end of the sensor clean and free of grease. NEVER use cleaning solvents of any type on the sensor! The sensor may be difficult to remove when the engine temperature is below 120°F (48°C). Excessive removal force may damage the threads in the exhaust manifold or pipe; follow the removal procedure carefully

1. Make sure the ignition is OFF, then disconnect the negative battery cable.

2. Locate the oxygen sensor. It protrudes from the exhaust manifold or exhaust pipe (it looks somewhat like a spark plug). It may be necessary to raise and safely support the vehicle to access the sensor.

3. Unplug the sensor electrical connector.

Note: There are special wrenches, either socket or open-end available from reputable retail outlets for removing the oxygen sensor. These tools make the job much easier and often prevent unnecessary damage.

4. Carefully unscrew the sensor, then remove the oxygen sensor from the manifold or pipe.

To install:

1. During and after the removal, be very careful to protect the tip of the sensor if it is to be reused. Do not let it to come in contact with fluids or dirt. Do not clean it or wash it.

2. Apply a coat of anti-seize compound to the bolt threads but DO NOT allow any to get on the tip of the sensor.

3. Install the sensor in the manifold or exhaust pipe.

4. Attach the electrical connector and ensure a clean, tight connection.

5. If raised, carefully lower the vehicle.

6. Connect the negative battery cable.
