"i have a 97 plymouth breeze, just bought it,the guy i got it from pop the eng light out.so i have a OBD reader,the codes are PO743-- TORGUE CONVERTER CIRCUIT ELECTRICAL, THE OTHER CODE IS P1491-- MANFACURER CONTROL.AUXILIARY EMISSION CONTROL. can antbody can help me. think yu'all so much."

you most likley have a blown fuse. the fuse for the connector and cig lighter are usually on the same circuit . if you have a owner manuel check and see which fuse is for the obd/cig lighter. if you dont have a manuel then check every fuse in the box and see if you find a blown one. the plug whare the scanner connects is what powers the scanner so if you cant find a blown fuse then you know youre not getting power to the plug for some reason.

what you want to do is take it to nissan and scan it with the consult2 diagnostic system to tell you which of the many things in the system have failed.
the EGR is the most common.

CIRCUIT DESCRIPTION
The shift solenoid valve SL is turned ON and OFF by signals from the ECM to control the hydraulic pressure
acting on the lock–up relay valve, which then controls the operation of the lock–up clutch.
DTC No. DTC Detection Condition Trouble Area
P0743

ECM detects open in solenoid SL circuit 4 times when solenoid
SL is not operated (2–trip detection logic)

ECM detects short in solenoid SL circuit 4 times when solenoid
SL is operated (2–trip detection logic)

Open or short in shift solenoid valve SL circuit

Shift solenoid valve SL

ECM
Fail safe function
If the ECM detects a malfunction, it turns the shift solenoid valve SL OFF
