PO743 definition is "TCC circuit Error".TCC stands for Torque Convertor Clutch.The diagnostic route for that code includes ohms testing,amps testing,and function testing the solenoid and the wires in the circuit.

02 explorer dtc p 0743 and p 0745 and od light flashes how to fix

Code 743 is for a problem with the torque converter clutch or circuit, and code 745 is for a problem with the pressure control solenoid.
Those two components are inside the transmission and would need to be tested by someone with the necessary tools and repair procedures.

First check for any cracked pipes leading into the intake manifold If all OK (with no codes showing it probably is OK) try checking the fuel pressure regulator. If you smell fuel from the pressure regulator vacuum side arm (when the vacuum line has been disconnected) it needs to be replaced.

Jeep trouble code 320 and 743

One problem at a time please. Let's get the engine running All the time! First, it seems that the battery is weak, perhaps old and past its prime (thus the jumper cables worked). Or, maybe you just need to clean off the battery terminals on the battery and the connecting cables. When did you replace the plugs, wiring harness, distributor cap and rotor last? Perhaps just cleaning them up will do the trick. Also, check that the grounding cables all over the engine compartment are clean and tight.

Igot these for codespo443 p1747 po755 po750 po743 po113

P0443 Evap purge control
P1747 Pressure control "A"
P0755 Shift solenoid "1" malfunction
P0750 Shift solenoid "A"
P0743 Torque convertor clutch circuit
P0113 Intake air temperature high input
For now leave the P0443 that is a evap code. for code 755 750 743 how did you get these code? clear it do key on engine running. the reason I say this is somewhere especially at the tranmission harness you are somehow disconnected. Check the transmission range selector switch closely, inspect the harness and do a wiggle test on the wires. some how your wire are disconnected

I have a error code reading of PO 743, Torque converter clutch, what does that mean?

It sounds like the convertor in the exhaust system is partly blocked. You will need to have this checked at a shop. Frankster016
