Good morning! Yes it is more than likely in the wiring harness...
The color of the wire in question is Dark Blue/Dark Green...PCM C-2 pin 10...Check for strong blue spark on plug #1...If not present disconnect PCM C-1 and coil #1 connector...Using an ohmmeter check the Dark Blue/Dark Green wire for open or ground...That is the essence of P2302...If open or reads to ground, cut it on both ends and re-run a new wire (of equal gauge) from point to point...Guru...saailer

OK. just follow the number on the ignition coils.
And the number on the cylinders are.
The FIREWALL side are 1,3,5, Starting from the belts location.

Sounds like either a bad plug wire, or coil pack. This is about all that would cause the misfire.

I have a misfiring problems with cylinders 1 and 6. Which ignition coil do i need to change?


Ignition coil one and six or course.The 3.7L uses separate ignition coils for each cylinder. The one-piece coil bolts directly to the cylinder head. Rubber boots seal the secondary terminal ends of the coils to the top of all 6 spark plugs. A separate electrical connector is used for each coil.
Because of coil design, spark plug cables (secondary cables) and a distributor are not used.
Two knock sensors (one for each cylinder bank) are used to help control spark knock.
The Auto Shutdown (ASD) relay provides battery voltage to each ignition coil.
The ignition system consists of:
² 6 Spark Plugs
² 6 Separate Ignition Coils
² 2 Knock Sensors
² Powertrain Control Module (PCM

2008 jeep code p2302 mean


do you want me to guess?
or do you want DIY testing advice.
mean, it means bad spark, from Ign.coil 1, (2 cyl wasted spark)

DIY , actual tests... per FSM. get one.
only 1 code. and comes back after clearing it?
full scan done?
how many miles on it, when was the last full tune up
page 412 opr, guide in glove box , did you do the 102k mile service?
new spark plugs and 6v wire sets? , now be the the time
not a new coil pack that be last choice.

p2 means factory code, and seems your scan tool works right.
many dont. or are blind to them or get them all wrong.

same car as my main car... JK,
i have the full JK, FSM. factory service manual, go it day 2.
the first thing to do, when doing DIY , is to open the hood
and see what engine you have, as diff, engines have diffr, EFI systems.
mine has the Trenton 3.8L V6. with MAP and TBW system.
TBW is throttle by wire. (map sensor is for speed density system)

P2302
P= powertrain
2= jeep private code, not USA fed, spec EPA codes.
3= Fuel and Air Metering (Injector Circuit)
02= Ignition Coil 1 Secondary Circuit- Insufficient Ionization

02= Ignition Coil 1 Secondary Circuit- Insufficient Ionization

this car has a coil pack and is WASTED SPARK
3 coils 6 spark plugs. wasted. (google what that means)
but is important to know because either spark plug can disturb
the current path here.

if my 6v did this, id do the 102k mile service. with NGK parts,.
or Bosch.

we , usually you get P03xx codes with it. misfire.

i open my fsm ,there are 6 tests. for this 1 failure
it says the spark duration is too short or nothing at all.
ill not type out all 6 tests nor the logic, (alldata.com has it)
step 1 is to :
clear all DTC
and key on (no start)
scan it, do you get 2302? now, not running,
that is correct the ecu test coil primary , before running, amazing,
if yes, the next steps are to see if the coil is bad (open primary)
or the ASD drive is dead.

How can i fix the missfire on a cylinder toyota corolla 2000 1.8ltr


First you need to retrieve codes from the Engine control module. You can buy a cheap code retriever at harbor freight and get the codes. After you get the codes, if it is P0301 it means cyl #1, P0302 = cyl #2, P0303=cyl 3 and P0304= cyl 4. For ex: if you got P0301 you should remove the ignition coil #1(near the front of the engine, where the pulley is) and change its position with the coil # 2. Also remove the spark plug #1 and change the position with the spark plug #4. Clear the codes and start and run the engine until the check engine light goes on. Check for codes and see if the code change for a different code. If it change the position observe which one is the change. If is P0304 you have a bad spark plug, If it is P0302 you have a bad coil. If it repeat P0301, you have either a low compression, bad injector/connector, bad intake gasket them you should continue your diagnostic. I hope this help you.

2003 mercedes Benz C240 codes P0300, P0301, P0302 and P0303. Please, help me how to fix?.


P0300 Random Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
according to this fault codes first mark ignition coils
3 ---------------- 6
2 ---------------- 5
1 ---------------- 4
RB-------------LB
this right banks and left bank, please remove Ignition coils with lids and spark plugs from right bank and swap with left bank, if fault code change as
P 0304 Cylinder 4 Misfire Detected
P 0305 Cylinder 5 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
You can Identify it's a faulty ignition system then next swap ignition lids from ignition coils be careful each coils have two lids one short and other long bit deference and when you remove and fix it to the car keep in mind correct order because each coil two different fire for two spark plugs don't mix up, if you mix it can create the fault code.if you detect any fault ignition coils or spark plugs or lids replace that and also whether god or bad recommend to replace spark plugs, find the right that's most important thing, if this way couldn't found the any ignition fault next step is check fuel presser, when the engine running fuel presser must be around 4.5 bar without engine running must be 4 to 6 bar if the fuel presser too low need to check two different things one is fuel pump other is fuel injectors, in this case you can swap injectors from right bank to left bank and find is the injectors leaking, if not leaking faulty fuel pump.is this information helped you? if yes please leave a comment,
