Will not start with out ,the code reader plugged in unplug the code reader and will stop gettig code p1768 and p0001


P0001 OBD-II Trouble Code: Fuel Volume Regulator Control Circuit/Open
Symptoms of a P0001 DTC will include MIL (Malfunction indicator lamp) illumination, although there may be other symptoms
If you get this DTC, you may want to try reading the codes using another (if possible) higher quality code reader. Even clear the code and see if the code comes back. This code is not common and sometimes is shown in error due to the design of the code reader (e.g. the code reader function is a secondary function of a tuner device).
P1768
Now with the code you said you had, P01768. DTC P1768 will set when TCM senses less than 3 volts at transmission control relay output (switched battery) terminals at TCM, prior to TCM energizing relay
Possible Cause
" Low battery voltage.
" Open fused B+ circuit to transmission control relay.
" Open ground circuit.
" Transmission control relay output circuit shorted to ground.
" Open transmission control relay circuit.
" Defective transmission control relay.
" Malfunctioning TCM. (very rare)

How can you fix internal soleniod in a transmission?


go after the P1768 code first. sounds like trans relay is not sending power to the solenoid pack. check fuse #2 {should be a yellow 20 amp fuse} in underhood fuse/relay box. if it's blown it will cause all these codes. the relay is marked EATX and is in the same box as fuse. should be in one of the corners of the box. hope this helps, let me know

P1768 code


i love posts with no words, 2000 GC? JEEP WJ ?
NO ENGINE OPTION STATED, and is 100% IMPORTANT.
i guess you scanned it > and it pops, DTCs.
only these, using a scan tool that can in fact scan all Jeep codes?
many cant, heck most cant.
P = power train.
1 = factory codes, so only the FSM tells the truth. jeep truth.
ouch my 2000 WJ fsm shows neither code. is this really a 2000?

think you typed in the wrong year, or car name.
here is the fist tranny codes for 1733
best i can find, is here, until such time you post real year, , engine and tranny type in car.
P17xx hell.

Recently the transmission is Stuck in 3rd


P1768 - Performance / Normal / Winter Mode Input Malfunction

P1733 - 3-4 Shift Malfunction
I would suggest you have the shift solenoid electrically tested to determine if they are at fault here or that you have a wiring issue or a failed Transmission control module. You will need the help of a transmission shop to diagnose this properly, do not just replace parts until you are sure they are the problem.

I have a 1999 grand cherokee. The check engine light came on with a P1768 code. If I keep the trans in the "drive" position and start off, it feels like the transmission is in 3rd gear. No...


Hi, Your like your jeep is in limp in mode, this is to keep you from burning up transmission and to get you some were off the road, the p1768 code means A/T Transmission Relay Output Always Off. This should be checked out by your local shop or dealer. but you should make sure that the fluid level is correct, if to low there is not enough fluid pressure for the solenoid's to engage the relays. Hope this can help you out. If i can help you anymore fell free to re post.
Thanks dodge tec

CHRYSLER CONCORDE WITH DIAGNOSTIC CODES P1768 AND P1792


P1768 MEAN TRANSMISSION RELAY ALWAYS OFF..WAS UNABLE TO FIND P1792..IF PROBLEM STARTED AFTER HEADS WERE DONE..LOOK CLOSELY AT AT ENGINE MAIN WIRING CONNECTORS AND GROUND CONNECTIONS THAT ARE ON ENGINE..LOOK FOR GROUND EYELETS NOT SECURED OR LOOSE..LOOK FOR ANY PINCHED WIRING AS WELL..MAKE SURE NO SPREAD TERMINALS IN CONNECTORS AS WELL..YOU CAN ALSO TRY SWAPPING ANOTHER RELAY IN PLACE OF TRANS CONTROL RELAY..MAKE SURE PART NUMBERS MATCH UP..
TCM(NGC)PIN 16 IS TRS T3 SENSE CIRCUIT..PIN 17 IS NOT USED...HAS TO DO WITH TRANS RANGE SENSOR..I DON'T THINK THIS CAUSING YOUR PROBLEM..
