Well My check engine light came on this past Friday and I read the code and reset the ce light. Yeaterday it came back and with the same code.

My experience with the "signal missing or faulty" has usually meant the sensor needs to be replaced unless there's more than one code thrown and then one can mask the other for the true cause of the ce or problem etc.

My question is where are the knock sensors and how much of a job is it to diy and what should I have for tools etc? where's the best place to order the parts from too?

Any help would be much appreciated.
