    AFR sensor questions

    Hi all. I have a few questions. I was riding today and my AFR gauge went from working perfectly to an error code E8. The manual says it was too hot for the sensor, bad sensor or too rich. I know the sensor was good since it worked for 3 hours and I'm not too rich so it must have been too hot.

    I re-callibrated it and it seems to work again. If it was too hot will it be ok once it cooled down?

    Do I need to install the heat sink adapter?

    I tried all over town and nowhere can I buy a new Bosch sensor. One place had an NGK that cost $219! Where do you guys buy them and how much do you pay?

    Thanks

    do not use a heat sink! thats the reason many ppl were having problems, I removed mine, if you do want a heatsink you can have mine for 10 bucks.
    I would try another sensor, the water jacket should keep them cool so no need to worry about overheating, unless you ran it on the trailer.

    I didn't run it on the trailer. So do you think the sensor is good since I recallibrated it and the error code is gone?

    We don't have Advance Auto here. None of the auto parts stores could help me.

    what part number did you give them? it's used on a few other vehicles, so they can definitely get them for you. find a place that has a 1 year warranty on them too, so if it goes out, you can take it back. i've seen the E8 code a few times. as long as it goes back to normal operation, don't worry about it.

    If it calibrates is good, be sure to pull the sensor from the bung to do the open air calibration. Also be sure to allow the injector to warm up before fireing the engine each time.
