    Default 7AFE Knock sensor.

    My Father is looking at an AE112R for his partner, However it has an issue with the Knock sensor. (I didn't even know they had one) The sensor is faulty / broken, and brings up the check engine light, seller has tried disconnecting it and the light still comes on as soon as the car is driven. Is there a workaround (apart from removing check engine light)?

    Default Re: 7AFE Knock sensor.

    i think the engine goes into some kind of limp mode without detecting the knock sensor? either way it's nice to have as a feature to the engine.
    I doubt that you can make a workaround what i can think of, maybe switch ecu to 4afe without knocksensor?

    Why just not buy a new one instead of removing the check engine light?
