I have a 2003 350z touring and sometimes the car won't start after multiple attempts it will start. the battery is good I even changed the starter thinking it was that. The Service engine light is not on but after running a scan I get service code p0327 knock sensor 1, circuit low bank 1, or single sensor. Will changing the knock sensor and harness resolve this ? Thank you

 

I had the same code for over a year. I never had issues with the car so I just drove it. I did eventually take the engine apart and found the harness was completely severed. The knock sensor was fine so its still on there. I replaced the harness and all is well. Not sure if thats causing your starting issues though.

 

Ok thanks for the input I'll take a look at it

 

Know a good spot I can order these parts at a good price ?

 

Just got the same code after a diagnostic test. Do you remember the cost to fix it?
