How does an oxygen sensor reduce exhaust emissions?

How does an oxygen sensor reduce exhaust emissions?

Originally called a “Lambda Sensor” when it was first used in fuel-injected European cars, the oxygen sensor monitors the level of oxygen (O2) in the exhaust so an onboard computer can regulate the air/fuel mixture to reduce emissions. It generates a voltage signal proportional to the amount of oxygen in the exhaust.

Is the oxygen sensor part of the exhaust system?

The oxygen sensor of your car measures the amount of oxygen in the exhaust gasses that exit the engine. The oxygen sensor is located in the car’s exhaust system, which allows the fuel injection and engine timing to work efficiently. This function is part of the vehicle’s emission control.

What does an exhaust oxygen sensor do?

Also known as the O2 sensor because O2 is the chemical formula for oxygen, the oxygen sensor monitors how much unburned oxygen is present in the exhaust as exhaust exits the engine. By monitoring oxygen levels, the sensor provides a means of measuring fuel mixture.

What does the oxygen sensor do on a Toyota Camry?

This article applies to the Toyota Camry (1997-2011). Your vehicle’s oxygen sensor measures the oxygen content in the exhaust, and adjusts engine parameters like the air-to-fuel ratio (AFR) to keep it running at its best. However, exhaust gasses are (by nature) hot and dirty, so the sensor can wear out with time.

What causes the p0136 code on a Toyota Camry?

Here are the most common issues that cause the P0136 code in the Camry. They are presented in order (somewhat) of most to least likely to cause the problem. Bad Oxygen Sensor – The oxygen sensor itself is one of the most likely reasons that P0136 is triggering your service engine soon light.

What is the OBDII code on a Toyota Camry?

P0136 is a common OBDII code that occurs in the Toyota Camry. It is typically caused when the O2 Sensor voltage is not within normal operating range. Bank one will be the side of the engine with cylinder 1 in the firing order. Toyota Camry P0136 Symptoms. Often, the only symptom of P0136 is going to be the service engine soon light.

How long does an O2 sensor last in a car?

Your vehicle’s oxygen sensor measures the oxygen content in the exhaust, and adjusts engine parameters like the air-to-fuel ratio (AFR) to keep it running at its best. However, exhaust gasses are (by nature) hot and dirty, so the sensor can wear out with time. Speaking very generally, a lifespan of 100,000 miles can be expected from the sensors.
