Quote: What are the symptoms of a bad oxygen sensor? Symptoms of a Bad Oxygen Sensor: When you have a bad oxygen sensor, your vehicle will run less efficiently, it can sometimes have a poor idle, erratic jerking at steady throttle, hard starting problems, cause the check engine light to come on, and will cause high fuel consumption. Quote: How do you know if your oxygen sensor is bad? Check this list to see if it's time to replace YOUR vehicle's oxygen sensors: Sudden decrease in fuel mileage.... Flashing check engine light or malfunction indicator lamp in the vehicle?s dash board.... Failure to pass smog.... Overall poor vehicle performance; rough idling, stalling, hesitation on acceleration, etc. When do you guys change your upstream oxygen sensor ? Do you wait until there's a DTC ? |

standard recommendation is 100,000mi I personally wouldn't push it past 75,000mi....it and the MAF sensor have some of the biggest affects on your fuel mileage. |

166k miles on the original O2 and everything appears to be fine. But I guess it might be time for a change soon. |

Change it/them when it/they becomes a problem. Actually first, I would try cleaning them and see if that buys you some additional time. There is no need to change them at 75k or 100k or whatever. I think that's my lulz for the day. Never had service bulletins that told us to change HO2S's because "when they reach a pre-determined mileage..." |

yes, dont throw parts at your ride just cause - if you have 100 buck scanner, you can see their voltages and then determine if they are working within the expected range and not slow or stuck - not very expensive but clean all 3 first - o2 x 2 and maf. |
