Number of O2 Sensors in a Chevy Equinox
The Chevy Equinox typically has two oxygen (O2) sensors. One is located before the catalytic converter, and the other is located just after the catalytic converter.
These sensors play a crucial role in informing the engine computer about the amount of free oxygen in the exhaust, which allows it to determine the optimal fuel mixture for power, economy, and emissions. If these sensors malfunction, it can lead to issues such as a check engine light, poor fuel efficiency, and potential damage to the engine and catalytic converter.
It’s important to note that the replacement of oxygen sensors should be done with high-quality OEM sensors to ensure proper recognition by the vehicle’s computer.

What symptoms does a bad O2 sensor cause?
First, what are the signs an O2 sensor may have gone bad?
- Check Engine Light Comes On.
- Noticeable Loss of Fuel Efficiency.
- Sulfur or ‘Rotten Egg’ smell from Exhaust.
- Black smoke from exhaust.
- Emission levels reach high levels.
- Your engine hesitates, skips, begins bucking or has power surges.
Should I replace all 4 O2 sensors at once?
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.
Is it OK to drive with a bad O2 sensor?
Can I Drive My Car With A Bad Oxygen Sensor? We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.
How many O2 sensors does a 2005 Chevy Equinox have?
The 2005 Chevy Equinox has two different O2 sensors. One is located on the down pipe from the headers before the catalytic converter and the other one is located on the exhaust after the cat.
How can I tell 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.
How much does it cost to replace an O2 sensor on a Chevy Equinox?
between $238 and $251
The average cost for a Chevrolet Equinox Oxygen Sensor Replacement is between $238 and $251. Labor costs are estimated between $51 and $65 while parts are typically priced around $186. This range does not include taxes and fees, and does not factor in your unique location.
Do you have to replace both O2 sensors at the same time?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream).
What are the symptoms of a bad O2 sensor?
Signs a Vehicle has a Bad O2 Sensor
- Check Engine Light Comes On.
- Noticeable Loss of Fuel Efficiency.
- Sulfur or ‘Rotten Egg’ smell from Exhaust.
- Black smoke from exhaust.
- Emission levels reach high levels.
- Your engine hesitates, skips, begins bucking or has power surges.
How do I know if it’s my catalytic converter or O2 sensor?
To check if it’s a clogged cat versus a bad oxygen sensor (when you don’t have a check engine light), grab a vacuum gauge. Connect the gauge to an intake manifold vacuum line. Start the engine, let it idle, and check the reading on the gauge.
How many O2 sensors do I have?
Every catalytic converter is required to have a couple of oxygen sensors. So if you have a single exhaust system, you probably have one catalytic converter and, thus, two oxygen sensors. Cars with double exhaust pipes, meanwhile, will be fitted with a total of four oxygen sensors.
