Modern vehicles have at least two oxygen sensors. An upstream oxygen sensor and a downstream oxygen sensor. The upstream oxygen Sensor is placed before the catalytic converter. It is responsible for measure the amount of oxygen in the exhaust gases. This information is used by the engine control unit (ECU) to adjust the amount of fuel injected into the engine.
When the upstream oxygen Sensor fails you will typically experience:
- check engine light
- reduced fuel economy
- reduced performance
- engine surging
The downstream oxygen sensor measures exhaust gases as they leave the catalytic converter. The downstream oxygen sensors readings determine the efficiency of the catalytic converter. When the downstream oxygen sensor fails, it will trigger the check engine light.
How much will it cost?
The typical cost for the testing and replacement is between $100-$550 for parts and labor. This price range is averaged across all passenger vehicles. The actual cost depends on your specific make, model and year. Depending on your specific vehicle, this cost may be lower or higher. This cost estimate is for the specific repair listed and doesn’t include additional, related items that may require repair.
Here is what is included:
- Inspection of the Oxygen Sensor
- Replacement if necessary
- Inspection of related components
