Keep getting a p1320 code - 2001 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.

That is a Manufacture Code we don't have

Don't know who clears the check lamp, but
that doesn't do any thing other than remove
the codes needed for a repair shop to find &
resolve the problems

check engine light on means some fault codes stored in your engine control module.
use this tool clear the fault code p1320.

use a code scanner tool to clear the p1320, it's cheap and easy.

Faulty ECM.Get the ECM tested it will cause this problem.These computers are exspensive.

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.

Hi,

The two codes seem to be related. The P0325 description is knock sensor circuit malfunction and the P1320 is ignition signal - circuit malfunction.

I'll summarize and then give links on more detailed articles I found. Basically the P0325 refers to the knock sensor and associated wiring. The P1320 refers to the ignition coil and wiring. Check the sensor, coil, and associated wiring.

I found some great articles:
P0325 - http://www.obd-codes.com/p0325
P1320 - http://autorepair.about.com/library/a/1i/bl039i.htm

Good luck!
