    no mate...its role is to put your motor in to safe mode (5psi) if it sensors the 1st signs of detting (metalic rattling sound) and after a fresh engine start it resumes normal boost

    is this the knock sensor i have heard about :hurl:

    yes it`s the knock sensor, it`s more than likely the loom connected to the sensor as it`s very prone to degradation over the 20 odd years it`s been in situ.You can bypass the sensor provided you are not getting det(sounds like rattling a pepple in a can) use a 1meg resistor to connect the 2 pins on the ecu side of the loom i.e the main harness the connector comes off.This will fool the ecu restoring full boost. do a search for the bypass n get down to maplins or similar.Its very easy to do. hope that helps
