Bottom line is I want to get it smogged and everyone I take it to has done little to nothing about it. Any and all information would be helpful as I am pretty lost with what to do at this point. I've done several hours of research and applied it to the car but I haven't gotten anywhere. Here are the codes:
P0325 - Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor)
- I haven't touched the knock sensor (yet) since it is my last priority at this point.
P0136 - o2 Sensor Circuit Malfunction (Bank 1 Sensor 2)
-I just replaced the rear o2 sensor so I'm assuming this has something to do with wiring. I'd like some second hand advice with this though...
P0443 - EVAP Control System Surge Control Valve Circuit Malfunction
- This has been the nightmare for me and I can't figure out what the issue is with this either...
Like I said, any and all information is greatly appreciated. Thanks

for the knock sensor, check to see if its connected, my friend recently bought a s14 and I used my scanner on it for check engine light, threw the knock sensor code, obviously you cant check to see if its cracked unless you remove it, but we were about to begin the removal and noticed the plug was just lightly on top of the mating plug, kind of floating, so I plugged it in and erased the code. other than that, if it is connected, I have had only good luck with OEM NISSAN knock sensors(others can pitch in if they used other brands and their light never came back on)
For the 02 sensor, the only thing I can say again is go NEW OEM(others may pitch in with other brands), some Nissans are picky if they are not factory sensors,(make sure you are erasing the codes after fixing the issues) the rear 02 sensor wiring is way easy to fix ,the primary 02 is harder (or not depending on you) due to the shield.
The evap one ..................idk, I don't have one on mine and im not sure why Im not getting the code for it. not sure if its because im bypassing the EGR (egr temp) with the 100k resistor????
hope that helps
