Are oxygen sensors all the same?
O2 sensors, also called lambda sensors or oxygen sensors, measure the proportion of oxygen in vehicle exhaust. Physically, there’s no difference between front and back O2 sensors.
What is a bad O2 sensor?
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.
What is an oxygen sensor used for?
Oxygen sensors are used in oxygen analyzers, which find extensive use in medical applications such as anesthesia monitors, respirators and oxygen concentrator so. Oxygen sensors are also used in hypoxic air fire prevention systems to continuously monitor the oxygen concentration inside the protected volumes.
How often to change O2 sensor?
Heated three and four-wire O2 sensors on mid-1980s through mid-1990s applications should be changed every 60,000 miles. And on 1996 and newer OBD II-equipped vehicles, the recommended replacement interval is 100,000 miles. A good oxygen sensor is essential for good fuel economy, emissions and performance.
What are the symptoms of a faulty oxygen sensor?
The most common symptom related to a faulty oxygen sensor is a sudden (significant and almost immediately noticeable) drop in your vehicles fuel economy. Other immediately apparent effects of a defective sensor is a drastic change in engine performance, overall power, and response.
