1. Lift the El Camino onto a machine lift and bring it up to a comfortable heighth to drudge at from underneath. Settle on the safety glasses before getting under the vehicle.2.
Since oxygen sensors overseer the fuel-to-air merge ratio, most cars that did not integrate catalytic converters in their exhaust systems did not gain O2 sensors. The sensor not individual regulates the fuel/air ratio, it again transmits the material to the powertrain force module (PCM) via a voltage term and makes compensatory adjustments. The fifth-generation El Camino is the single chart of the vehicle that used a combined catalytic converter-oxygen sensor emission force method.
Instructions
Set the catalytic converter near the centre of the El Camino's undercarriage and displace it to the front Y-pipe for the O2 sensor.
3. Replace the wire outlook from the O2 sensor to the nearby wire harness plug. Unplug the sensor wire from the harness plug.
4. Spray the exposed threads of the sensor with a generous amount of penetrating oil.
5. Place the wire through the closed end of a box-end wrench and place the wrench on the hexagon-shaped base of the sensor. Turn the sensor counterclockwise to unthread it from the exhaust pipe. Remove the oxygen sensor. If necessary, apply heat to the exhaust pipe area and expand the metal of the pipe to help remove the sensor.
6. Apply a light amount of anti-seize compound on the threads of the replacement sensor. Do not let the compound come into contact with the sensor's head.
7. Screw the sensor into the exhaust pipe's porthole by hand and then snug it tightly with the wrench.
8. Plug the oxygen sensor wire back into the wire harness plug.
