Knock sensor code.do I really need 2 replace 4 smog. if is bad would it pass smog in ca,.
If the code is p0325, it should be repaired, HOWEVER, on nissan products from 1996 to 2002, a p0325 does NOT illuminate the check-engine lamp. Knock sensor on that vehicle is for PING control not for emissions reduction. On other vehicles (say a chevy with a p0325) it WILL light the check engine lamp which is an automatic smog fail.

The knock sensor is a major pain in the a..s to change I would suggest taking it to a reputable shop for a second opinion to see if they realy performed the work. Also with OBD11 (2) diagnostics if you have multiple misfires its not the wires its something else, also if you got a code for a misfire it would be specific as to which cylinder is misfiring. My best guess would be to get your coil checked.

IF YOU REPLACE SENSORS YOU HAVE TO ERASE PCM CODE TO TURN OFF CHECK ENGINE LIGHT.IF YOU DONT IT WILL KEEP LIGHTING UP.
