What is the sensor after the catalytic converter do?
Oxygen Sensors, commonly referred to as O2 sensors, are part of your vehicles emission system. The purpose of the downstream, after converter, sensors is to monitor the quantities of harmful exhaust gases flowing into and out of the catalytic converter to ensure the converter is working properly.
What’s the difference between Bank 2 and bank 1 sensor?
Bank 1 or B1 refers to cylinders 1-3. Bank 2 or B2 refers to cylinders 4-6. Sensor 1 or S1 refers to the sensor before the catalytic converter. Sensor 2 or S2 refers to the sensor after the catalytic converter. Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement.
Where are Bank 1 and 2 O2 sensors located?
Summary. If your DTC code says: Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after the catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
Where is the O2 sensor on a catalytic converter?
Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
Where is Bank 2 located on an engine?
Located on Bank 2 means it is located at the engine side with cylinders 2, 4, 6, 8, etc. Bank 2 Sensor 2 is the second sensor on the engine’s exhaust pipe, usually behind the catalytic converter.

What is a bad O2 sensor?
Bad O2 sensors are one of those car problems that most drivers tend to postpone until more serious problems occur. These symptoms will rarely cause any immediate damage, but over time, if left unattended, they can cause damage to the engine and other systems mainly through improper air-fuel mixture.
What is a catalyst monitor sensor?
Catalyst sensors are often used to detect hydrocarbons but rely on the presence of oxygen to function. How do catalyst sensors work. Catalyst sensors have two basic elements: a detector which contains a catalytic material sensitive to flammable gases, and a compensator element which is inert.
What is an O2 sensor?
An O2 sensor is an electronic sensor designed to measure the oxygen level in the exhaust fumes that exit the engine after combustion. All combustion engines burn fuel by mixing it with oxygen, which is essential to run the engine.
What does a catalytic converter OBD II mean?
What does a Catalytic Converter OBD II mean? OBDII (On Board Diagnostics II) systems are required by Federal law on all passenger cars and light trucks manufactured since 1996. It is a computer on board the vehicle that monitors the engine and emission control equipment to verify that all systems are working properly.
