The oxygen sensor is a critical component of modern vehicle emission control systems. Studies conducted by the United States Environmental Protection Agency (EPA) show that failed oxygen sensors result in high emissions during the Federal Test Procedure (FTP). Many states have inspection and maintenance (I/M) programs to detect and correct high emitting vehicles but most programs have a repair cost limit. The high retail price of some oxygen sensors often exceeds the I/M repair cost limit, resulting in high emitting vehicles not being repaired. A study of oxygen sensor prices, designs, and applications was conducted to identify reasons for high oxygen sensor prices. The study showed that many oxygen sensors are constructionally and functionally the same but their retail prices vary greatly.
