The amount of oxygen found in your fuel affects the efficiency of your internal combustion engine. Your Toyota Corolla oxygen sensor helps to monitor the oxygen proportions. This small electronic device then sends its information to the Electronic Control Unit (ECU) which then is able to make small adjustments to control the efficiency of the combustion process.

An engine needs the correct amount of oxygen to work properly. Problems are caused when either too much or too little oxygen is there.

Fuel that is unstable can cause damage to your catalytic converter and can lead to costly repairs. Depending on the year that your particular automobile was made determines how frequently the oxygen sensor should be replaced. For those that have an unheated sensor in a vehicle made between 1976 and the early 1990s, it should be replaced every 30,000 to 50,000 miles. For vehicles with a heated sensor made between the mid 1980s and the mid 1990s, change it every 60,000 miles. For heated sensor vehicles made after the mid 1990s, replace it every 100,000 miles.
