| Post subject: | O2 sensor question |
Hello again I've heard that the life time of an O2 sensor is about 5 years, is this a fact? I ask it because my xb9 is, how can I explain?, it's not missing out, it's inconstant at about 2000 2500 rpm, it's like she cant make up her mind about the amount of fuel to inject??? It can be the exhaust I'm running but some times its to much, it's like I cant get the throttle right, kind of feeling??? No errors on ECMspy, any light on the subject will be appreciated By the way are this part numbers for O2 sensors correct (x9sx from 2005) GM delco #25162693 GM OEM= 8990469 superseded to 25162693 Bosch= 12014 Walker= 250-21001 Denso= 234-1001 Airtex= 553071 SNG= SN1-15 NTK= 21002 Thanks |

For a replacement, you just need a single wire replacement. If you want a heated sensor (3 wire), which may be cheaper, you will need to wire it up to it is heated when the ignition is on (orange and white wire would work). Gunter has been looking into O2 sensor failures, so in readiness for a reponse from him, it would be good if you logged some data and PMed him. But, in terms of it hunting, have you done a TPS reset recently? |

last TPS reset was 6000km ago, I can do it again and see if gets any better I don't want to change the sensor, but, what do I gain on fitting a heated one? better, worse, or the same but cheaper and whit more wires? I'm was just thinking, instead of going to see some boobies on the CARNAVAL I can do the TPS reset on Tuesday  thanks pash |

Probably cheaper, cos they are in all cars... They get up to operating temp earlier than single wire ones. Single wire, unheated, was good enough for Buell. TPS reset before you spend any money...

I've heard some very negative comments about NGK sensors. Is there a NO O2 sensor option Pash? - You know - the resistor thing. |

Just unplug it and dsable the error code... But you have no protection against running lean... |

Disconnect it and see what happens. |

does the same thing pops a lot and shot's of The strange thing is it enters the close loop region, does this whit 5.1% on tps and doing 1400 (goes from 400 to 1400 on her one alone no throttle on my part) not so shore on the O2 sensor any more??? the ecmspy shows no error whit or without the lambda connected |

replaced the plug's, try an older eeprom program, checked the connection's, problem continues removed the O2 sensor, tomorrow going go try and buy a new one, an if still doesn't work I'm blind from there on |

no can do gunter, she don't old that long, she starts spiting fire from the inlet and goes down eventually. when I removed the plugs they wore black not that brown coal normal look, I'm afraid to mess something out by forcing her to work |

Perhaps it's worth a try to log as long as the bike will keep running. |

I've try it but cant do it, she goes down, doesn't old Tried to buy a new O2 sensor on the car parts supply, but, as they are the experts, bike lambda sensors are not the same as cars so piss of, I've event noticed but do bikes rum on water? I've been filing whit gasoline perhaps that's the problem??? Disconnected the head temp sensor, she goes to the roof but stays there, can this be the problem? I've read that the temp sensor is problematic |
