at least 3 o2 sensors are available.
Leaning correctly, slide the truck under the car and look for the O2 sensor. Depending on the year of construction of the truck, there is only one sensor on the passenger side near the gearbox or, on newer models, several sensors both in front of and behind the catalytic converter.
Tahoe initially replaced the entire Chevy blazer. Tahoe has been available with V8 engines since 1996 and has four O2 sensors (also called oxygen sensors). Two of these sensors are located in front of the catalytic converter and monitor the mixture of fuel and air conditioning in the exhaust gases.
Probably two O2 sensors.
It is best to replace the sensors in pairs. For example, if you replace the left downstream sensor, you must also replace the right downstream sensor. The code is likely to be set on most vehicles within 3060 days of the first sensor replacement.
The oxygen sensor is an important part of a car’s engine. If you think your oxygen sensor is dirty, you can clean it by first removing the sensor from your house in the car and then soaking the sensor in gasoline overnight.
Here are some of the more common signs that the oxygen sensor is faulty.

On GM and Chrysler V6 and V8 engines, cylinder number one is usually the left cylinder of a rear-wheel drive car or truck.
Bank 1 sensor 2 = This O2 sensor is located just after the catalytic converter, on the side of cylinder # 1. 1 which is bank 1. Sensor 1 row 2 = This O2 sensor is located immediately in front of the catalytic converter, on the side of cylinder # 1. 2 exactly like bank 2.
Lambda sensors are located in the exhaust gas stream, there is at least one lambda sensor in front of the catalyst and usually one in each exhaust manifold. Depending on the design of the exhaust system, one or two may be placed behind the catalytic converter to check its efficiency.
O2 sensors, also known as lambda sensors or lambda sensors, measure the amount of oxygen in the car’s exhaust gas. There is no physical difference between the front and rear O2 sensors. They work the same way, but the vehicle’s computer uses the readings for different purposes.

The O2 sensor is mounted in the exhaust manifold to monitor the amount of unburned oxygen in the exhaust gas as the exhaust gas leaves the engine. Checking the oxygen content in the exhaust gases is one way to measure the fuel mixture. It tells the computer if the fuel mixture is rich (less oxygen) or lean (more oxygen).
Cars with O2 sensors have at least one sensor in front of the catalytic converter and one in each of the car’s exhaust manifolds. The actual number of lambda sensors for a car depends on the year, make, model and engine. Most model cars, however, have four oxygen sensors.
