Signs You Need a New O2 Sensor

An illuminated check-engine light could be a sign of a more serious issue, such as with the catalytic converter, or something as minor as a loose gas cap, so further investigation is always required. It could, however, indicate that there is a problem with your O2 sensor or even another part of your exhaust or emissions system. Any repair shop should be able to read what triggered your check-engine light, and a mechanic or auto parts store may perform this service for free.

Other signs that you need a new oxygen sensor include a rough idle, misfiring spark plugs, lack of power, stalling or a significant increase in fuel consumption. Those symptoms could also be indications of other problems, but the EPA says that replacing a bad oxygen sensor can improve fuel economy by as much as 40 percent, so clearly that is one place to look if your vehicle develops a greater thirst for gas. If your vehicle fails an emissions test, a faulty O2 sensor may be to blame for this as well.

A new oxygen sensor can cost from less than 15000 JMD on some models to 90,000 JMD or more on others, but that doesn’t include labor, which can vary widely by vehicle because of where the sensors are located. As a result, the full cost of oxygen sensor replacement may vary greatly depending on the type of vehicle you drive.
