What does the code p0743 mean on a Dodge?
This is an electrical problem code. Could be a problem to the harness to the Torque Converter Clutch (TCC) solenoid, the TCC solenoid connector or the TCC solenoid it self. What does this mean? The cost of diagnosing the P0743 DODGE code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city.
What does p0740 mean on a powertrain computer?
P0740 Diagnostic Theory for Shops and Technicians. When the code P0740 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is seeing greater than a 200 RPM difference between the rotational speed of the Torque Converter and the Transmission Input Shaft.
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 are the symptoms of an OBD code p0740?
P0740 Symptoms. Check Engine Light will illuminate. Vehicle will not shift into the highest gear at freeway speed. Decrease in fuel economy. In unusual cases, there are no adverse conditions noticed by the driver.

What does it mean when your torque converter code is p0743?
If it does, that means it was not set by mistake. Then, they can continue with the diagnosis to determine what is causing the P0743 code. a number of technicians have found that mechanics have replaced the lock up solenoids and torque converters when they do not need to be replaced.
What is the PCM error code p0743?
In the case of Error Code P0743, the PCM is reading higher than 200RPM difference between the rotational speed Torque Converter and the Transmission Input Shaft. When the Torque Converter Lockup Clutch engages, the ratio between the converter RPM and Input shaft RPM must be 1:1.
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 does the p0700 code on a Dodge Charger mean?
It is a OBDII code and not just a Dodge specific code. It is possible to get the P0700 code without any other code registering with your Dodge Charger. If you get no other code it means that the transmission control circuit is malfunctioning.
What causes a torque converter error code p0743?
There are many factors that may lead to the occurrence of Error Code P0743, which include: Dirty or low transmission fluid. Failed TCC solenoid. Failed TCC assembly in torque converter. Short or ground problem in circuits or wires.
In the case of Error Code P0743, the PCM is reading higher than 200RPM difference between the rotational speed Torque Converter and the Transmission Input Shaft. When the Torque Converter Lockup Clutch engages, the ratio between the converter RPM and Input shaft RPM must be 1:1.
What causes a torque converter clutch code p0743?
Some common causes of code P0743 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors Defective TTC solenoid Dirty, contaminated, or degraded transmission fluid that prevents proper operation of the TTC solenoid. Failed or failing PCM or TCM.
What causes stop and go traffic code p0743?
Heat is what kills transmission, which is why we usually hear that stop and go traffic is hard on the transmission. In the case of Error Code P0743, the PCM is reading higher than 200RPM difference between the rotational speed Torque Converter and the Transmission Input Shaft.
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.
What does error code p0743 mean on a Honda Accord?
Error Code P0743 is defined as Torque Converter Clutch (TCC) Solenoid Circuit Electrical. This means the PCM (powertrain control module, also known as ECM or engine control module in other vehicle makes) is seeing a fault in the TCC, which is contained inside…
What does p0743 mean on a torque converter?
P0743 Meaning The Torque Converter Clutch (TCC) solenoid valve is activated, with the gear in D4, by the Transmission Control Module (TCM) in response to signals sent from the vehicle speed and the Engine Control Module (ECM). Lock-up piston operation will then be controlled.
How much does it cost to diagnose a p0743 code?
The cost to diagnose the P0743 code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. How much do you know about cars? When is the code detected?
How does the ECM detect an open solenoid?
By performing a voltage drop test, the Engine Control Module (ECM) detects that the Torque Converter Clutch (TCC) solenoid circuit is open or shorted.
Some common causes of code P0743 could include the following- Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors Defective TTC solenoid Dirty, contaminated, or degraded transmission fluid that prevents proper operation of the TTC solenoid. Failed or failing PCM or TCM.
By performing a voltage drop test, the Engine Control Module (ECM) detects that the Torque Converter Clutch (TCC) solenoid circuit is open or shorted.
What are the codes for a Dodge OBDII?

Why is the OBD code reduced to p0740?
Because the engine will be operating with reduced speed and load, overall fuel consumption and emissions output will be reduced.
