How to Change the Oxygen Sensor on a 1992 Toyota Camry

80

The Camry is a mid-size car that has been manufactured by Toyota since 1980. The 1992 Camry has one oxygen sensor, which reads the amount of oxygen in the exhaust gases and sends the information to the engine’s fuel delivery system. That system then adjusts the amount of air and fuel being delivered to the engine, based on the reading. A faulty oxygen sensor can cause an increase in emissions and a decrease in fuel efficiency. Replacing the oxygen sensor is a relatively easy task that requires just a few basic tools.

Tools Used: Tools, Penetrating oil, Flat-head screwdriver, Ratchet, Oxygen sensor socket, Open-end wrench, Anti-seize compound

Change Oxygen Sensor – Removal

Open the hood and locate the oxygen sensor at the base of the exhaust manifold. You will see wires coming out of the top of the oxygen sensor. Apply penetrating oil to the base of the oxygen sensor where it threads into the exhaust manifold. Disconnect the engine wiring harness from the wiring on the oxygen sensor. Use a flat-head screwdriver to pry the connectors apart if necessary.

Place the oxygen sensor socket over the top of the oxygen sensor and turn the sensor counterclockwise. If you do not have an oxygen sensor socket, use an open-end wrench.
