Toyota Camry O2 Sensor Problems
The engine determination module (ECM) on your Toyota Camry uses a digit of sensors to function the injectors on the fuel step. The O2 sensor contributes to this method by monitoring the exhaust stream outlook elsewhere of the engine, a critical ball-buster for engine efficiency and emission force. When problems foster in your O2 sensor, you Testament indication an exaggeration in fuel consumption and a chop in engine performance. Here are some other data you should apprehend approximately this ECM Element.
This will avoid costly repairs if the threads in the exhaust pipe become damaged.
The beginning oxygen sensor is normally mounted on the front cut of the front exhaust main and the moment sensor is mounted on the rear of the front exhaust pipe. If you have more than two of these sensors, it is likely the third unit is located on the back pipe, right after the catalytic converter.
Function
The heated oxygen sensor is used to monitor the amount of oxygen in the exhaust stream going through the exhaust pipe and report this information to the vehicle computer. The computer then uses this information and data from other sensors to regulate the amount of fuel/air going into the combustion chamber according to the engine conditions, speed and load for better performance and minimum of emissions.
Features
Your Toyota Camry oxygen sensor is a small unit with a cylindrical body; it's about the size of a spark plug. This heated sensor is equipped with three tail wires. On average, an oxygen sensor has a service life of about 50,000 miles, but heated sensors like the one on your vehicle model may last up to 100,000 miles.
Problems
There are several reasons the oxygen sensor on your Toyota may go bad: silicone in antifreeze, RTV sealer, and gasoline additives and carbon that results from rich mixtures of fuel that coat and disable the active elements in the sensor; bad electrical connections and shorts; and end of service life. In most cases, you will notice about a 10 percent or more increase in fuel consumption as a result.
Replacing
The threads on the oxygen sensor tend to stick to the exhaust manifold over time, making it difficult to remove. In this case, it is necessary to use penetrating oil, a line wrench or six-point oxygen sensor socket to remove it.
