Code P1320 Ingnition Signal

Vehicle when you step on it will not rev above 3k and does not go any faster. customer complained it stubles sometimes when started, i haven't noticed that.

I have ohmed all the the coils, checked the power and the ground. basically checked everything listed in the service manual. Everything checks fine. I am tempted to think it has jumped time a tooth, but have never seen that on a maxima.

However there is a TSB on this code that says replace all 6 coils for this code. One can understand my hestitancy towards replacing all of them. And they give a part # for replacement which matches the current coils in it.

compression check? did you smoke the intake? Do you have a graphing scope? Try scoping the crank/cam/ign coils together, that should tell you alot. Then try scoping the coil power and grounds with the cam/crank signal and the ignition coils. All of that scoping should be done while driving and recording while the vehicle is acting up.

I have seen a pathfinder with the V6 break the flywheel center out and wedge itself back against the flywheel and drive normal with no noise ( that was fun figuring out) it did some weird ignition/misfire/driveability stuff

The timing belt tensioner setup is pretty crude on these nissans I've never seen a belt jumped but i have seen them shred and fall off :( It should be easy enough to pull the top cam cover and check the timing marks.

If i remember correctly i think the coils have to be flashed into the PCM per vehicle
 
When you checked the resistance on the coils, was it running or just sitting?

Have you noticed these symptoms or is it just what the dood is saying he thinks is happening?
 
it is a chain not a belt. i scoped coils, cam, and crank running, compression checked fine does not run like a intake leak. i ordered the ignition coils i let you know if it fixes it.
 
Probably the knock sensor killing the ignition advance...read on

MIL "ON" with DTC P1320 stored in the ECM Intermittent spark knock (detonation)
The cause may be one or more of the ignition coils. Refer to the Service Procedure below to resolve the incident, if it should occur.

SERVICE PROCEDURE:
Determine if one or both of the symptoms listed above exists and perform the appropriate procedure(s) listed below.

Procedure For MIL "ON" With DTC P1320 Symptom
Check Self Diagnosis Results (using CONSULT-II) to confirm DTC P1320 (Ignition Signal Primary) is stored in the ECM. NOTE :Single or multiple cylinder misfire codes (P0300 - P0306) may be stored in the ECM with DTC P1320.
Check the ECCS wiring harness for a broken or damaged wire.

If the ECCS harness has a broken or damaged wire that is causing the symptom(s) noted above, repair the harness and verify the incident is resolved.
If the ECCS harness does not have a broken or damaged wire and is NOT causing the symptom(s) listed above, proceed with step 3 below.

Replace ignition coil(s) with the one(s) listed in the Parts Information table, and verify the incident is resolved.
Procedure for Spark Knock (detonation) Symptom

Use CONSULT-II to check Self Diagnosis Results for any stored DTCs in the ECM.

If there is a DTC(s) stored in the ECM, refer to the applicable Service Manual to repair the vehicle.
If no DTC (s) is found, proceed with step 2 below.

Verify the type of gasoline used in the vehicle.

If unleaded regular (non-premium) gasoline is used, advise the customer to use unleaded premium gasoline to eliminate the spark knock (detonation).
If unleaded premium gasoline is used and no other source for the symptom is found, proceed with step 3 below.


Parts Information Table
Replace ignition coil(s) with the one(s) listed in the Parts Information table, and verify the incident is resolved.
 
yes i scoped both power and ground, that is the TSB i am talking about. the cure is Ignition coils they say, we shall see, i have not recieved yet. And i am the dealer, dealer would have put coils on it without even checking the harness and if it didn't work they would charge you anyways.
 
:eek: This thread has kids old enough to drive now!
