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.
