Number of O2 Sensors in a Chevy Silverado
The Chevrolet Silverado typically has two types of O2 sensors: upstream and downstream sensors. The upstream O2 sensor is located on the exhaust manifold or manifolds, while the downstream oxygen sensor is located behind the catalytic converter.
Some Silverado models are equipped with high-tech wideband O2 sensors, which can measure the exact air-to-fuel ratio of the mixture and report it to the ECU, resulting in better performance and fuel economy.
In summary, a Chevy Silverado generally has two O2 sensors: an upstream sensor located on the exhaust manifold or manifolds, and a downstream sensor located behind the catalytic converter.

How many O2 sensors does a V8 have?
three oxygen sensors
Traditional V6 and V8 engine vehicles typically have three oxygen sensors: a left bank and right bank upstream sensor as well as a downstream O2 sensor. 4 cylinder transverse engines usually have two O2 sensors: one upstream and one downstream.
Will an O2 sensor work without a catalytic converter?
Will an O2 sensor work without a catalytic converter? Yes they do work with or without a converter present. Oxygen sensors do just that: they measure the amount of oxygen present in the exhaust gasses.
How many 02 sensors does a 2004 Silverado have?
4PCS Oxygen Sensor for 2003 2004 2005 Chevrolet Chevy Suburban 1500 Silverado 1500 Escalade Tahoe Sierra 1500 Yukon XL 1500 5.3L Upstream + Downstream.
What code does a bad O2 sensor give?
6.0 COMMON OBDII CODES
| Code | Description | Location |
|---|---|---|
| P0154 | O2 Sensor Circuit No Activity Detected | Bank 2 Sensor 1 |
| P0155 | O2 Sensor Heater Circuit Malfunction | Bank 2 Sensor 1 |
| P0156 | O2 Sensor Circuit Sensor Malfunction | Bank 2 Sensor 2 |
| P0157 | O2 Sensor Circuit Low Voltage | Bank 2 Sensor 2 |
How many O2 sensors are on a Chevy Silverado?
Set of 4 Oxygen O2 Sensor for 2014-2017 Chevrolet Silverado 1500 4. 3L 5.
How do I know which O2 sensor is bad?
Performance by monitoring fuel air mixture. And catalytic converters. When they start to fail your fuel economy and emissions can be affected. It’s likely you’ll see a check engine.
Should you replace all 02 sensors at the same time?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.

Should I replace all O2 sensors at once?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.
Do I have to replace all 4 O2 sensors?
Do I need to replace all of the sensors at once? It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right.
