I do not know about the OP's car but in my car the sensors are not exactly... MarcW - Saturday, 21 September, 2013, at 11:48:55 am |
The 4 are identical in 986, different front vs. back in 987 *NM* Boxsterra - Sunday, 22 September, 2013, at 3:33:11 pm |
Not based on my experience when I changed the ones in my 02 Boxster 2.7l car... MarcW - Sunday, 22 September, 2013, at 4:44:02 pm |

Well, I can't explain it. I recall swapping the front and rear and while they ... MarcW - Tuesday, 24 September, 2013, at 4:39:33 am |
Yes, there were different lengths and part numbers. mikefocke, '01S Sanford, NC - Tuesday, 24 September, 2013, at 3:36:04 pm |

Here is a link to our write-up on replacing the O2 sensor... RainyDayGarage - Saturday, 21 September, 2013, at 4:00:51 pm |
The sensors consist of two electrical circuits: The actual sensor and the heating element.... MarcW - Saturday, 21 September, 2013, at 5:45:32 pm |

Come on. $100 (make that $200 or even $400) worth of parts is a problem?... MarcW - Monday, 23 September, 2013, at 4:24:12 pm |

I have been running since Thurs with the cleared codes. Nothing.
It might be that the IM readiness stuff is still playing out, but whatever it is, it is not condition critical.
But I want to be clear, these codes are suggestive of O2 problems and nothing else? The sensors are clearly the most obviousl thing, but since they are like $100, I don't want to be just throwing parts at a problem.
$100 is a problem if it doesn't fix the issue. Then it is just a waste. JM-Stamford,CT - Wednesday, 25 September, 2013, at 1:40:53 pm |

As reported last time, I cleared the code and drove. I wanted to see if the car just threw a random code. I have since passed inspection etc. I have not been using the car very heavily due to a (now resolved) hip replacement. But it has been at least a few thousand miles and about a year and a half.
The return of the code is certainly suggestive that the sensor is, indeed failing. But apparently it is dying a VERY slow death. I am going to do the same as last time. Clear the code and see what happens.
If the code returns again, I will have to replace the sensor and I will likely replace both sides at the same time. I have seen it written that changing both is not necessary, but I am less than convinced.

No. It simply suggests the fault is not a solid fault and after enough engine start/warm up cycles.. MarcW - 8 years ago |

Is that suggestive of a wiring problem rather than a sensor problem?
That's a heck of a lot of views above *NM* Gary in SoFL - 8 years ago |
must be one heck of a common problem.... JM-Stamford,CT - 8 years ago |
Five years on ... Still have not changed the O2 sensor - code is back first time in 3 years.... JM-Stamford,CT - 4 years ago |
I am having a similar issue... Tony in Whittier - 4 years ago |
Specifically what codes? *NM* Boxsterra - 4 years ago |
