    Default fuel composition sensor on 2003 suburban

    Took my 2003 suburban to get the fuel lines redone yesterday, the technician told me to keep an eye on the fuel composition sensor ( fuel comp sensor) he said that it looks swollen from corrosion and may fail, but it is a costly repair that they didnít say had to be done. Does anybody have any experience with this sensor? From what little bit I researched it, it has something to do with the flex fuel, and from other post Iíve read I can just unhook the sensor. any input would be greatly appreciated, the last thing I want to do is get stranded somewhere from a needless sensor.

    thanks for the reply, after doing a lot of research I think thats the way I'm going to go. it deosn't sound like flex fuel is ever going to be run thru my vehicle anyway. have you any used one of these or know anybody that has? I would like to make sure it works before I spend the bucks on it
