Hi! I am new to this site. I joined because I am sure that someone on this site has experienced what I am going through with my Maxima. I have a 2000 Nissan Maxima. I have replaced all 6 coils, and spark plugs for my car. However, the engine light is still on...smh. I took it to the local Advanced to scan for the problem. The same P1320 code is still coming up, but now it's saying igniter circuit malfunction. I don't know what else to do. I have replaced the cam sensor, motor mounts, struts, coils, and spark plugs on this car. The car is driving good, but I just cannot get that engine light to stay off. Any advice would be appreciated.

 

Are you only the P1320 code or is there another code as well? Your use of "igniter circuit" has me wondering.

P1320 Possible Causes from the Nissan FSM:

Harness or connectors (The ignition primary circuit is open or shorted.)
Power transistor unit built into ignition coil
Condenser
Crankshaft position sensor (REF)
Crankshaft position sensor (REF) circuit

 

i had that code on a 2000 maxima after replacing all ignition coils with aftermarket coils. The problem was the coils, I ended getting oem parts and that code went away.

Did you use factory Nissan OEM or aftermarket?
