Re: i keep getting a p1320 code on my 2000 nissan maxima
The most common cause that will trigger the P1320 code is the ignition coils, one or more ignition coils may have failed. Even tough the coils may be working OK, the resistance for one or more of the coils is greater or smaller than the Engine Control Module (ECM) is expecting. Measuring the resistance with the coil out of the vehicle may not show any failures, usually the coil fails under heavy conditions (hard acceleration) or certain temperatures.
The P1320 code means that there is problem with the "Ignition Coil" or the wire to the ignition coil. For some models without individual ignition coils the Ignition Coil is inside the distributor and the distributor need to be replaced to fix the problem.
Testimonial: "i know this i did the test with the coils in the car and they read fine also the connectors. how about the crankshaft postion sensor? will it hurt to drive it like that when the lights to the TCS and SLIP come on also? doesn't that affect my brakes? all the coils were replaced and plugs also. i got premium gas in it still throws the same code. any more suggestions??"

Disconnect the battery over night to reset the engine code. If it comes back, then the problem has not been repaired. The P1320 code means that there is problem with the "Ignition Coil" or the wire to the ignition coil. Good luck!
code p1320 refers to ignition signal--circuit malfunction===causes--wiring---ignition coil/ module---ignition system---CKP sensor---ECM IT is the same as flask code 0201
first to check is the crank sensor then the ignition module.
What I found on the internet was that P1320 is a transistor in the ignition coil, that turns on the primary side of coil
Maybe a 1320 is similar to a Generic PO303 eg: coil #3 middle plug firewall side
You can put the P1320 into the computer & continue on for the answer
Maybe a bad #3 cylinder coil, if the code actually is accurate. On my Lincoln, even professional scan tool software, isn't always of any use, sometimes, because of coils not grounding properly & coming back on the TPS Sensors
ahh yes. you got a tricky one. this code is very misleading because the definition of p1320 is the ignition signal primary which alot of owners have popping up after changing a starter or something of the liking.
the fix is replacing your ignition coils. this is a common problem on the 2000-2001 maximas. this i know from experience of being nissan tech and ex-maxima owner. if you are handy you can order the coils for about $325 dollars and change the coils yourself and you will save hundreds of dollars as the dealerships will charge $600-$750 dollars. this should clear up any any hesitation and misfiring(shaking). please rate 4 thumbs up if helpful.
I found a thread on Maxima.org relating to the P1320 error code.
Specifically, 2000-2001 Maxima's have had this problem. It seams as
though everybody agrees that the error is caused by the ignition coils.
We've never had ours changed, so I'm doing that. Nissan was going to
charge me approx $600 (plus tax) for parts and another $180 for labor.
The job take a whole 30 minutes to replace the 6 of them, and you can
get the 6 ignition coils at O'reilly's for $325. I changed three last
night and the car seems to be doing better. I'll replace the other 3
tonight and see what happens.
Also, when testing the car, the car seems to "shake". I'm not sure
if this is related to the P1320, but if we turn off the AC the "shaking"
2000 maxima are famous for having bad coils - those cost about $350 if you dealer isn't trying to rip you off (otherwise they will charge $600). I also read you can get an aftermarket coil at Autozone.
The P1320 code is essentially a coil primary voltage problem. This is traceable using a labscope or accurate DVOM and perhaps you can isolate one or two coils that still work but are close to failure...but there is a nissan service message recommending replacement of ALL coils with updated/improved models to prevent this type of failure. TCS/SLIP is traction control. Most likely you have a speed sensor issue. Be aware, some vehicles can falsely illuminate TCS because of low tire pressure in a single wheel.
