2005 GC shows a code c1. What does it mean? - Jeep Cars & Trucks

check your distributor 5.7 s had hiccup code may read for cam or crank problem but the timing would get a little out of spec with the distrib-------------------------https://chevytrucks.org/chevy-p1345-engine-code/ --------------

C1 means that prior codes need to be cleared. Press MODE/RESET button to clear Code and restart
heater.

year 2000? not really huh?
seems the year is wrong,
so if that is true ,is car wrong too, JEEP and grand cherroke wrong too?
for example the 2011 Compass / Patroit
2011 (tsb to replace Pcm) ( have TSB, google finds it easy)
see?

1: get it serviced yet?
2: read the FSM WJ book yet, do all tests it tells you to do ?
there are only 2 paths.
they do it , you do it.?
which one?

WJ 00 (dead end, no code there, OP posted wrong year,. )

U codes are specific to specific jeeps. and years.
posting wrong car....
makes answers impossible. did you scan it yet?

but one thing, we do , is check fuses first.
if the ABS module does not talk, if in fact it is ABS code.
and scan it, first. too.
fuses then scan.
or fail.

these are factory codes, not usa federal codes like P-0300
so post full car spec, and engine, type for best answers.
lets say car is a 2005 GC.
and U0121
see chapter 8E-72 in fsm tells you what to do,
if car is 3rd gen jeep GC, then it has this buss.
the below is the buss, the can c bus
the code means PCM cant talk to the ABS box.
id be all over fuses. and resetting them all.

are you doing spark or timing a cam? what? what is JOB?
it dont matter, the engine, ecu does that, (magic)
but if it has a coil pack like my 3.8 then the coil pack must
be wire right and is marked. clearly on the pack.
they have USA jeeps and Export. country never stated here. sad huh?
and use differnent spark systems (3 types used, but 2 common)
per below.

v6.
is this not a Cheokee? the non Grand ended in 2004. so...
ill go with GC 2005, v6 3.7L
the v6 began in 2005, not 2004, but, maybe yours is the first./

the 3.7 has coil over plug, spark, 6 coils.
and the harness is fixed to those coil so all firing order are
dictated in the ECU/PCM (hard coded)

VIN engine code, K. (not stated)

and already asked, and answered .

my 3.8 (2004) jeep.
is 1,2,3,4,5,6
and is like this.

mine uses wasted spark system.

so post VIN, or tell what engine is really there.
and the true year. or build date (sticker)

so my answer is.. 2005 GC, 3.7L V6, not I-6
it has 6 cops, "coil over plugs" 6 induction coils
and runs same firing order, as the old I6 did.
1-5-3-6-2-4
but the I6 4.0liter runs a coil pack and is quite different.
these;


times 6
all laced in, hard.

code p0175 refers to --system too rich bank 2. causes ---intake blocked---EVAP canister purge valve---fuel pressure---EGR system---injector/s HO2s The first thing I would replace is the o2 sensor in bank2 Use genuine only as the cpu settings may be different to cheapies.. check air filter and the purge valve.

Any chance you have a check engine light on ?
If so I would have the computer scanned for trouble codes.

Hi Priscilla,When you say code 34, what is it showing as; P0034? If so, it means that you have a Turbo Charger Bypass Valve Control Circuit Low, according to this website: http://www.obd-codes.com/trouble_codes/

I beleive the audio system has to be reset when the battery has drained.There is a specific code you need to reset it.If it's not in the maintanece manual you'll have to call the dealership

encrypted software ,dealer only----yes i know you are showing a reading but it doesnt mean anything or if it does it shows a different code .so your snap on or mac tools scanner is a waste of time and money.Nearly all new motors from 2005 are using encrypted software to stop general mechanics like me from working

Check the low pressure sensor and the hi pressure sensor to be sure they are operating properly. Also check compressor relay and all fuses.
