My mistake about the swap thing; not sure what I was thinking that day.

Your car has two knock sensors, one for each bank, and they are both underneath the intake connected to the outside with a pigtail harness, that is why you have a four wire connector.

P0402 is not one of the code that would trigger the fail safe mode; there must be another code. have you try to check for codes again? The OBDII connector should be behind the coin box.

N.E.O.
