Is there an O2 sensor in the exhaust?

Fuelmiser Oxygen Sensor – Original Equipment… The oxygen sensor, otherwise known as a Lambda or O2 sensor in your exhaust, is essential to ensuring your car runs smoothly. Here at Repco, we are proud to stock a wide range of oxygen sensors, to ensure you can always find the right one for your needs.

What does the O2 sensor on a catalytic converter do?

This O2 sensor monitors the operating efficiency of the catalytic converter. If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor, it is a sign that the catalytic converter is not working properly.

When do I need to replace the oxygen sensor?

If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor, it is a sign that the catalytic converter is not working properly. Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter.

What is the OBD code for bank 1 sensor 2?

P0138 is the OBD-II generic code indicating that the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream. This article applies to the Lexus IS, RX, GS, LS, and ES (2005-Present).

When to replace the O2 sensor in your car?

In simple terms, O2 sensors are designed to wear out over time. As such, if your vehicle has driven 60,000 to 100,000 miles on with its existing sensors, depending on make and model, you may want to consider replacing its O2 sensors before they fail.

Where are the O2 sensors on a V-6 engine?

Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.

This O2 sensor monitors the operating efficiency of the catalytic converter. If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor, it is a sign that the catalytic converter is not working properly.

What are the symptoms of a bad O2 sensor?

Bad O2 sensor symptoms include poor gas mileage, rough engine idle, starting trouble, and even failure of the catalytic converter. Often, the check engine light will come on to provide ODII trouble codes to check with a code reader.
