fault code 22 knock sensor
 

after a spirited drive a pop and a splutter earlier i now have fault code 22(knock sensor) do i need a new 1 or reset ecu my intercooler pipe came of from the turbo at the same time put that on and it now feels like its hesitating and i have this fault code would the pipe coming of caused it to set of the knock sensor and i need a ecu reset to put back the timing etc or is it the actual sensor has had it and i need a new one? what causes knock anyway? Thanks Guys :thumb::thumb: car is a my93 wrx import always run on 99 fuel

disconnect your battery then run it again if it pops up again replace the sensor

I have got one if you need......

just do ecu reset

if the OP doesn't want it i might, what are the numbers on it?

cheers.
