FAQ:

Q: What is a bad O2 sensor?

A: Bad O2 sensors are one of those car problems that most drivers tend to postpone until more serious problems occur. These symptoms will rarely cause any immediate damage, but over time, if left unattended, they can cause damage to the engine and other systems mainly through improper air-fuel mixture.

Q: How often should O2 sensors be replaced?

A: Bosch recommends replacing unheated one- or two-wire O2 sensors on 1976 through early 1990s applications every 30,000 to 50,000 miles. Heated three and four-wire O2 sensors on mid-1980s through mid-1990s applications should be changed every 60,000 miles.

Q: What does an O2 sensor do?

A: An O2 sensor is an electronic sensor designed to measure the oxygen level in the exhaust fumes that exit the engine after combustion. All combustion engines burn fuel by mixing it with oxygen, which is essential to run the engine.

Q: How many O2 sensors do I have?

A: Depending on the year of your car there could be up to 5 o2 sensors located along the exhaust system. Fortunately, the computer DTC will pinpoint the specific o2 sensor that needs to be tested. Using the DTC, you can refer to your owner’s manual to locate the sensor.
