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)
