If your Toyota turns on the check engine light, oxygen sensor may be the culprit. Fortunately, sensor failures are fairly rare. In recent years, most frequent need for oxygen sensor replacement was due to the catalytic converter thefts – Toyota Prius was the most frequent victim. Fortunately the epidemic of catalytic converter theft has subsided. But there is a chance that your Toyota’s oxygen sensor will fail. The sensor lives in an environment of hot exhaust gases, and is bombarded by small particulates – tough environment by any standards. When it fails, the onboard computer will turn on the check engine light. Unfortunately, the check engine light can come “on” for thousands of conditions, so a professional inspection and diagnosis is a necessity.

Many car owners dread the check engine light, yet it is one of the most useful inventions of the last 30 years or so. Your vehicle's onboard computer can illuminate the check engine light for many reasons. As a matter of fact, there are literally hundreds and hundreds of conditions that make the check engine light come “on”. The reason for that is that there are sensors throughout your car that report information about various subsystems to the onboard computer.  If any of the subsystems does not function within the acceptable parameters, the check engine light will come on. The good news is that the sensors pay attention to many aspects of your car's operation that in the past went unmonitored and unnoticed.

Modern cars, on the other hand, monitor many aspects of operation and alert you whenever there are developing problem ... read more
