Some of the following diagnostic techniques might be helpful in resolving some of the following lean oxygen sensor and fuel trims or related fault codes: P0101, P0137, P0138, P0140, P0141, P0157 ...

This caused two additional codes to store in the system along with the O2 sensor code. Ultimately, loosening and retightening the two ground strap bolts allowed us to clear all the codes from memory.

Answer: Even though the code is for an O2 (oxygen) sensor, it is pretty obvious the problem isn’t with the sensor itself. There are three possible types of faults which can cause oxygen-sensor ...

When Should I Replace The O2 Sensor? The answer to this question is complex, as these sensors are not your standard maintenance items. No indicator lights on your dashboard or other means could hint ...

A new oxygen sensor can cost from less than $100 on some models to $300 or more on others, but that doesn’t include labor, which can vary widely by vehicle because of where the sensors are located.
