Some manufacturers state that it is a general tune-up item that should be changed every 40,000 miles, while others have different criteria. It is best to look at the service schedule for your vehicle to determine when it needs to be changed.
The oxygen sensor on a vehicle will need to be changed about every 100,000 miles for the newer vehicles. An older vehicle might need this part to be changed more often. If this part is working properly, there is no need to change it, no matter how many miles are driven.
Your O2 sensor is a "part that is designed to wear out". there is no standard on replacing them, but if your car is running fine, and your check engine light comes on, and stays on, it's probably an O2 sensor.
Only when it goes bad, in most cases it will not go bad.
you should never have to change your oxygen sensors. The only time you have to is if the PCM (powertrain control module) is not recieving any input from them. This would cause an MIL (engine light) to illuminate.

The check engine light for the 2001 Isuzu Rodeo often comes on because of a sensor that is damaged or malfunctioning. The most common sensor is an oxygen sensor and when reset, this often allows the light to be reset.
Passwords should be changed every month.
According to my dealer, it should be changed at 150,000 km.
Code PO131 typically refers to a diagnostic trouble code (DTC) related to the oxygen sensor circuit in a vehicle, specifically indicating a malfunction in the heater circuit of the oxygen sensor (often the upstream sensor). This code can lead to issues with fuel efficiency and increased emissions if not addressed. It usually prompts a check of the wiring and connections to the oxygen sensor, as well as the sensor itself for proper functionality.
