Question about Nissan Maxima

DTC 1320 and 301 - replaced #1 coil and all of the spark plugs. Reset codes - 1320 appeared again in current codes. Is there a way (without replacing all of the coils) to test and determine which coil is setting the code?

    Plug wires are attached. The code was previously together with the 301. Any suggestions on how to determine if a coil is bad / testing methods? Identifix solution - replace them all. There's got to be a way.

  • lbarrus Apr 28, 2010

    Anyone have any other ideas regarding testing the coils - identifix lists several who have replaced all of the coils - elderly customer who cannot afford to do that. code 1320 still there.

    2000 Nissan Maxima GLE - engine is not skipping. Replaced Coil #1 and all of the plugs. 1st coil was aftermarket, replaced with genuine Nissan coil - ran vehicle for 20 minutes - check engine light remained off. Drove into the inspection bay to test, check engine light illuminated. No Misfire Codes. Put the scanner on it, DTC 1320 again. Any additional ideas without replacing all of the coils.

Check your plugs.....if one of the coils is misfiring the plug should show signs of running rich.

Just take out the spark plugs *(good thing is you just replaced them so they all started out bone white!) and "read" them. Look for the one thats out of place.

Then change that coil out with a new one and clear codes.

Of course...if the code reoccurs you only have two *(or four perhaps?)coils left now don't you?

I hope this helps!

Are your car's ignition coils mounted separately on the top of each cylinder?

    It seems like your car is a new model car ( you didn't mention the year of car) and coils are separate for each cylinder, what you can do is when the engine is running open one coil ( it must be attached with the spark plug cap) and hold it near a grounded surface ( like engine block) and see which one doesn't spark, do it one by one ( you should install back the one you opened before other wise the engine will stall).
    Have a look at it and let me know if you need more advice.

Check your spark plug wires to be sure they are firmly connected.

    Coils very rarely go bad, but you can check it with a multi-testor by attaching it to the terminals while someone cranks the engine. If it shows any voltage it's good. Did you consider the alternator or a loose wire grounding out?

Harley Davidson Fault Codes

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.
2- Push odometer reset button in & hold.
3- Turn ignition switch to Ignition and release odometer reset button. Background lighting sould illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word "diag" should then appear.
4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.
5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer
6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC's the code will be displayed or the word "none" will appear if there are no DTC's. Push the odometer reset button again to view additional codes if they exist.
7 - Record the codes.
8 - If DTC's are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC's again by repeating steps 1 to 9. If the code is current it will reappear.
9 - Press and release the odometer reset button to continue to the next module.
10 - Turn Ignition switch to OFF.
On models not equipped with a tachometer "No Rsp" will appear when the tachometer identifier is selected.
"No Rsp" will also appear if the run/off switch is in the off position when doing this procedure.

2006 grand prix gxp 5.3. When you are driving normally it will miss from 50mph and up. When you punch it it doesn't miss a beat. I cleaned the maf sensor and air filter, Plugs were replaced.

It's probably a coil breaking down , have a scan tool hooked up an have misfires checked to see which cylinder is missing .
Ignition Coils
Each ignition coil has an ignition 1 voltage feed and a ground. The engine control module (ECM) supplies a low reference and an ignition control (IC) circuit. Each ignition coil contains a solid state driver module. The ECM will command the IC circuit ON, this allows the current to flow through the primary coil windings for the appropriate time or dwell. When the ECM commands the IC circuit OFF, this will interrupt current flow through the primary coil windings. The magnetic field created by the primary coil windings will collapse across the secondary coil windings, which induces a high voltage across the spark plug electrodes. The coils are current limited to prevent overloading if the IC current is held high too long. The spark plugs are connected to their respective coils by a short secondary wire. The spark plugs are tipped with iridium for long life and efficiency.
Drive it long enough like that (with it misfiring ) the check engine light will flash . This is to warn that a catalytic converter damaging event is taking place . This would also set a DTC - diagnostic trouble code

Misfire cyl 3 replaced plugs swapped coil and inj comp 175 across the board

check for a crack or carbon track in the distributor cap for no 3 plug lead
It could be a wiring or harness connection for no 3 injector or a problem ECM control for no 3 injector ( check for moisture in the connections and or bad pin conditions

I have a 2003 jeep grand cherokee, It started

wow, no engine option stated, and no DTCs.

4.0L I-6 or 4.7Liters?

WHY DO THAT FIRST. $$$$ parts first.

why not do a tune up first.

you swap in the most expensive parts first? ouch,

The PCM tells you when ckp or cmp fail, with DTC codes

so its not that. but you never posted ALL DTC errors. why not do that.?

do a real tuneup? heat (spark plugs, filters.)

if you have P030x errors,

eg: p0301 is cylinder #1 is misfiring (3 ways to do that not JUST spark)

eg: P0300, random on all cylinders. (fuel mix wrong) or never tuned up.

Misfire 101; (example P0301 DTC)

P030x codes, are all just about spark, misfire is caused by 3 things, (at least)

1: sure spark. weak. (tuneups work as does hV wires sets if no COPS) if 1 cop is bad move it to other location, does failure follow the move>???????? buy new cop boots if engine has cops.

COPS means coil over plug, so v6 has 6, v8 has 8.

coil packs have 3 coils inside for v6 and 4 for V8. called wasted spark to any tech.

2: low compression, think of your v6 (is it) as 6 engines, not 1.

3: wrong FUELING rates. including air leaks to 1 cylinder.

if engine has EGR that too, will cause gross misfiring.

so can an air leak near one intake runner, causing 1 cylinder to misfire.

why not scan it with a real scan tool that can see ALL jeep codes

then post all DTCs found. both idling and driving for 45mph or 1/2hr.

with these facts and what engine is there we can do the remaining tests.

free book

The tune up is this and filters.

do the tune up, new wires, and plugs using correct spark plugs not some bs, magic ones, use spec, plugs first. its in the manual.

then HV wire set on 4.0L,

if cops V8 , 4.7L try new boots on them. or swap them to find bad one.

the USA car V8 has coil on plugs

misfire means ONLY that this cylinder has weak COMBUSTION

its not weak spark only, that is only 1 cause of poor combustion.

post DTC\'s driving and we can fix it

the best tool is the

Innova 3160 scan tool, that is what I use on home cars.

it does all jeep codes, ALL.

i can drive , and scan and log DTCs.

and gather lots of facts on errors.

that is always the best way,

you can not fix cars today with out owning a scan tool.

unless , luckiest man on earth. (guessing)

post what engine. some cars have diffr. motors.
the displacement,? 1.8L , 2.0, 2.5, etc. liters.
some have 1 coil some have 4 cop coils.
my guess, is the CEL comes on ,you attach a scan tool and
you get P0300 (random misfire, , ) right? and no other DTC codes.
and what are the driving symptoms.
300s have many causes, not just spark, not in the least.

2000 lincoln ls misfire

In my experience the most common reasons for a misfire diagnostic trouble code (DTC) for a specific cylinder like P0306 which I am guessing is the DTC you recieved without have any other DTC's like a P0300 (random multiple misfire) is either the coil or the injector. There is always the chance you have a faulty connector at either the injector or the coil. It kind of hard to help you completely as I need to ask you a few questions in order to go further. Here are the first set of questions. After you clear the code, does it pretty much come right back ? I know the spark plugs are new but have you looked at the spark plug in cylinder number 6 ? Is it wet or black due to fuel ? I understand you are able to pull DTC's but are you able to look at any freeze frame data with the scanner you are using ? You can reply/comment here or email me directly at and maybe we can work through this without having to replace a bunch of parts that don't need replacing. One thing you may want to try which can be a little bit of a pain with the injector but if it is a hard code or a code that comes back quickly after clearing the DTC but you may want to swap the injector (since you already replaced the coil) with an injector from another cylinder. If you recieve a new DTC for a misfire in the cylinder you put the injector that was originally in the number 6 position then more than liklely it's the injector that's faulty. Injectors can get dirty and kind of stick open and drip fuel when it should be off/closed. This will also cause a wet or black spark plug in that cylinder. Yes vacuum leaks and fuel pressure can cause this by the way but in most cases you will also get a P0300 as well.

1997 saturn sc 1 code Po 341 comes up, I have replaced the spark plugs and wire set, I also replaced the fuel filter. The car won't start at all now but before I replaced the above parts the car would run...

The fuel filter won't help with this DTC, but helps otherwise.
Camshaft position sensor...can be a few reasons for this. Since you put new plug wires in, check the coil pack for cylinder #4 and also the spark plug for that cylinder even though it is new. A different problem in that cylinder can cause that spark plug to fail prematurely.
Here is a more detailed explanation....
