P1768 Acura Ricks Free Auto Repair Advice

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)

Do the easiest things first:
Check the battery earth lead (bear in mind that if you disconnect the batter you will probably have to re-enter the radio code). Check where it connects to the body/engine block - make sure it is clean and secure.

Then check every other earth lead you can find

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

the P1768 means "Performace/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.

just google honda DTC code P1768. you will get lot's of answers

I have tow of the three requested codes. po300 is misfire detected at multiple cylinders. See po301-306 represent the cylinder # misfire. So 301 is cylinder #1 misfire.

po420 is Catalytic Converter Efficiency Failure

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..
