Can you clean a Subaru O2 sensor?

According to the search results, it is generally not recommended to clean an O2 sensor. Replacing the sensor is the preferred course of action when it becomes faulty. O2 sensors are designed for replacement, not cleaning, and attempting to clean them may void the warranty. The high temperatures in the exhaust system make it unlikely for O2 sensors to get dirty. While there are some claims that cleaning O2 sensors might provide temporary improvement, it is generally more effective to replace them.
If you suspect that your O2 sensor is faulty, it is best to consult with a mechanic or automotive professional for proper diagnosis and replacement.

WD-40 was designed to provide a corrosion protective coating for nuclear missiles. The volatile oils and coating residue will damage an oxygen sensor.

Is it better to clean or replace O2 sensors?

A dirty or faulty oxygen sensor is meant to be replaced, not cleaned.

However, O2 sensors can become sluggish over time.
