I have a Jeep Grand cherokee 2002. The gears have gone into limp mode. i am getting the following error codes: P0703, P0403, P0702, P1130, P2125, P0700, P0579. I am guessing there is a electrical box gone...


no engine options stated, now THAT is a challenge, x100.
4.0L or 4.7L?? 3.1L, 2.7L AND 4.7HO (EXPORT)
ASKING WITH OUT ENGINE TYPE IS HOPELESS. !!!
i Just wing it, and try to guess.
this is not the Diesel engine , right? is this a USA car or export?
this is a USA site so we must ask that. (nobody does but...must)

the FSM covers this, the factory service manual.
45RFE and 545RFE automatic transmission
the p07 are all transmission errors from the TCM brain.
p04xx is EGR, failure, so skip that. for now.
a/t limp means the TCM , see's gross errors. why it does, takes TESTING. by a technician,
not Gue$$ing, .


here is book for 2002. (USA only, ok ?)
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

see emission page for all DTCs.
700, 702 and 703
702 is not listed, is that a non USA market engine?
i see lots of posts on 702 or Diesel , why is that? and missing in the gas, FSM i have. ??????
700 means ,Ive got tranny errors see others for why.
703 is brake lamp stuck on failure.
579 --
Cruise control system inoperative 1130
P1130 Oxygen Sensor Circuit Low Variance (Bank 1, Sensor 1)
my guess is this is the first scan in 10 years. and all those codes
are antique? reset the PCM and drive and see the codes that
are real for NOW.
(all cars do that after writing them all down as you did)

2125 (not in my usa FSM oddly)
but googling finds one diesel here.
Throttle/Pedal Position Sensor/Switch "E" Circuit

that is all i can do , with
NO COUNTRY STATED
NOR which of 5 ENGINES USED .
sorry !

OBD p1242 ,p0703,p0702 grand cheeroci


ok so 1242 is sensor power supply high input ,0703 is detected de-acceleration with no brake switch activity and 0702 is fault with trans control unit i'd guess your having running/accelerating problems ,have the codes wiped and road test and see if problems continue if they do i'd get the ECU checked out as a first step

You're in LIMP MODE, the system is preventing any further damage to your car by limiting the speed insisting that you see a service center ASAP.

P0702 p1685 fault code on 2.7crd merc transmission


DTC P0702 - Transmission Control System Electrical
There is a code in the ****** control module and need to check harnesses and wiring, as first step.

DTC P1685 - Skim Invalid Key
Transponder ID (in ignition key) is monitored with ignition on. DTC will set if transponder ID read by Smart Key Immobilizer Module (SKIM) does not match any transponder ID's stored in SKIM memory. Possible Causes:
- Incorrect VIN In PCM
- Invalid SKIM Key Present
- No Communication With SKIM
- No VIN Programmed In The PCM
- PCM SKIM Trouble Codes Set

I would suggest clearing all these codes, and drive it until the problem arises again, or the check engine light comes on, and then check for codes again. To clear the codes you will need to remove the negative battery cable, and touch it to the positive cable, for about 15 seconds. Then re hook and all the modules will be reset. If this isnt work, visit your Trans Service.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

I have a P0702 transmision trouble diagnostic.how


Transmission Control System Electrical=P0702 code,
Have you talked to a jeep dealer yet,
Ask if there are any TSB's on this problem.
Technical Service Bulletins from Jeep when they find and solve different complaints.
What ever is doing this is a soft code,A soft code is one that will clear it's self with the cycle of the key to off then on and code goes away,But have them check history codes to see if it is there.it sounds like it is going into limp mode,this feature is when the computer sees a transmission falt it wont up shift,so you don't harm the tranny,but will let you limp to a shop to get repaired.have you ever noticed the speedometer going to 0 then this happens?
that would be the output sensor.
