What does the code p0740 mean on a torque converter?
The p0740 code clearly states a problem with the electrical circuit to the torque converter clutch solenoid and not a problem with the torque converter itself. Diagnosing the P0740 is often pretty straightforward. You need to find some measure values for your specific car and transmission model, though.
When does the solenoid set the p0740 code?
On most vehicles, the module will set a P0740 code when it detects an electrical fault with the TCC solenoid or the TCC control circuit. Also, as was mentioned, on some vehicles, the code may set when the TCC’s performance is out of range due to a mechanical problem.
What does p0740 mean on a Jeep Wrangler?
Jeep Wrangler P0740: Torque Converter Clutch Circuit Malfunction April 6, 2019 by Jason P0740 is one of the most common transmission trouble codes. It means that the Wrangler ‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit.
What is the code for torque converter clutch solenoid?
Code P0740 indicates that the control module detects an electrical problem with the torque converter clutch solenoid or the solenoid’s circuit. Note: Although code P0740 is a generic code specified by the Society of Automotive Engineers (SAE), the code’s definition may vary depending on the vehicle manufacturer.

What are the symptoms of a p0740 DTC?
If any additional transmission related DTC’s appear in addition to the P0740, an electrical failure is likely. Symptoms of a P0740 trouble code may include: Malfunction Indicator Lamp (MIL) illuminated (a.k.a. Check Engine Light) Minimal decrease in fuel economy, this will not affect engine performance Causes of this DTC may include:
When does DTC p0745 set the solenoid?
Chassis related codes are labeled “C” and body system related codes are labeled “B” codes and these can cause drivetrain issues if they affect a sensor that is also used by the heating and air conditioning system. DTC P0745 sets when the PCM or TCM has detected an abnormality in the electronic pressure control solenoid circuit.
What causes an OBD2 error code of p0740?
The P0740 error code is triggered when there is a problem in the circuit to the Torque converter clutch (TCC) solenoid. Any of the following problems can cause it:
What does the p0740 code on a PCM mean?
What Does the P0740 Code Mean? The P0740 code indicates that the powertrain control module (PCM) has observed an unusual behavior within the torque converter clutch circuit.
What does the p0740 code on a torque converter mean?
What the P0740 code means. What the P0740 code means is that the powertrain control module (PCM) has detected something unusual within the torque converter clutch circuit. The powertrain control module can vary the application of the torque converter clutch for optimal vehicle performance.
The P0740 error code is triggered when there is a problem in the circuit to the Torque converter clutch (TCC) solenoid. Any of the following problems can cause it:
What Does the P0740 Code Mean? The P0740 code indicates that the powertrain control module (PCM) has observed an unusual behavior within the torque converter clutch circuit.
When to set p0740 code for clutch solenoid?
Once the module deems conditions are correct, it commands one or more TCC solenoid valves to engage the TCC clutch. On most vehicles, the module will set a P0740 code when it detects an electrical fault with the TCC solenoid or the TCC control circuit.
