What causes the p0744 code to be stored?
The P0744 code may be stored if the torque converter clutch solenoid is faulty, or if the torque converter is defective. Other causes may include: Blocked internal transmission fluid passages. Mechanical internal transmission failure.
What to do if your torque converter code is p0744?
There are many ways that a technician can address a P0744 code, including: Checking and replacing transmission fluid; if the fluid is found to be very dirty, flushing the system and replacing the torque converter may be required. Checking and replacing any shorted or faulty wiring, connectors, and circuitry.
What is the diagnostic code for torque converter clutch circuit intermittent?
P0744 is a diagnostic trouble code (DTC) for “Torque Converter Clutch Circuit Intermittent”.
What does diagnostic code p0700 stand for?
Diagnostic Trouble Codes P0700 through P0799 are transmission related OBD-II codes. Any code within this range point to a transmission related fault.. CV (constant-velocity) axles, (also known as half-shafts), are used in front-wheel drive vehicles to transfer the engines power from the transaxle to the two drive wheels.

P0744 is a diagnostic trouble code (DTC) for “Torque Converter Clutch Circuit Intermittent”.
Why does my transmission have a bad code?
One of the most common reasons for this code is debris obstructing the flow of transmission fluid throughout the transmission valve. The mechanic should change dirty transmission fluid, and ensure that the fluid does not have a burnt smell, or lacks the proper pressure.
What are the possible causes of Nissan p0744?
P0744 NISSAN Possible Causes 1 Faulty torque converter clutch solenoid valve 2 Torque converter clutch solenoid valve harness is open or shorted 3 Torque converter clutch solenoid valve circuit poor electrical connection 4 Low transmission fluid level 5 Dirty transmission fluid
What does fault code p0743 on OBD II mean?
What Does Code P0743 Mean? OBD II fault code P0743 is a generic code that is defined as “Torque converter clutch (TCC) solenoid –electrical”, and is set when the PCM (Powertrain Control Module) detects an abnormal voltage in the electrical control circuit of the TTC ( T orque C onverter C lutch) solenoid.
When to use lock up on Nissan p0744?
Lock-up operation, however, is prohibited when A/T fluid temperature is too low. When the accelerator pedal is depressed (less than 2/8) in lock-up condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.
What causes a torque converter clutch code p0744?
Nonetheless, some common causes of code P0744 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and or connectors in the affected control circuit
Is the ODBII code p0744 an extended warranty?
ODBII CODE P0744 No Extended Warranty… This was the second time this happened to me. I was driving 80 mph on the highway about 2 weeks ago when I heard a relatively whining sound which resulted in loss of power.
What are the possible causes of a Nissan loss?
P0744 Nissan Possible Causes. Faulty torque converter clutch solenoid valve. Torque converter clutch solenoid valve harness is open or shorted. Torque converter clutch solenoid valve circuit poor electrical connection. Low transmission fluid level. Dirty transmission fluid.
P0744 NISSAN Possible Causes 1 Faulty torque converter clutch solenoid valve 2 Torque converter clutch solenoid valve harness is open or shorted 3 Torque converter clutch solenoid valve circuit poor electrical connection 4 Low transmission fluid level 5 Dirty transmission fluid
What does p0744 mean on a torque converter?
Note that code P0744 rarely indicates a faulty transmission, or a general failure of mechanical components in the transmission or torque converter.
Why is my torque converter clutch code p0744?
The P0744 code is primarily set by mechanical faults such as sticking Torque Converter Clutch (TCC) solenoid or valves in valve body. Since the problem continues after you replaced the transmission fluid, then you may have a problem with the Transmission Valve Body.
ODBII CODE P0744 No Extended Warranty… This was the second time this happened to me. I was driving 80 mph on the highway about 2 weeks ago when I heard a relatively whining sound which resulted in loss of power.
What causes an OBD code of p0742?
The P0742 code can be caused by a variety of things. The following are the most common: Dirty transmission fluid Low transmission fluid Faulty torque converter clutch solenoid valve Internal mechanical problem with the transmission Torque converter clutch solenoid valve harness or connectors could be bad
When to use fault code p0748 in OBD II?
OBD II fault code P0748 is a generic code that is defined as “Transmission fluid pressure (TFP) solenoid –electrical”, and is set when the PCM (Powertrain Control Module) detects a failure or malfunction in either the electrical control circuit of the transmission pressure control solenoid, or a failure or malfunction of the pressure control
