How to Change an Oxygen Sensor on a 1992 Toyota Camry

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 engines 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.

Instructions

Removal

1

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.

2

Apply penetrating oil to the base of the oxygen sensor where it threads into the exhaust manifold.

3

Disconnect the engine wiring harness from the wiring on the oxygen sensor. Use a flat-head screwdriver to pry the connectors apart if necessary.

4

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. Loosen the oxygen sensor and remove it from the exhaust manifold. Dispose of the old oxygen sensor by recycling it or returning it to an auto parts store.

Installation

5

Apply a thin coat of anti-seize compound to the threaded end of the new oxygen sensor.

6

Insert the new oxygen sensor into the exhaust manifold. Turn the oxygen sensor by hand to make sure that you dont cross-thread it.

7

Tighten the oxygen sensor with the socket or open-end wrench. Be caul not to overtighten the sensor.

8

Connect the new oxygen sensor to the wiring harness.
