[SOLVED] U1424 Code: How To Fix Implausible Engine Torque Signal

The automobile fault code U1424 indicates a problem with the Transmission Control Module (TCM) or its related components.

The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light. The cause of this fault code could be a faulty TCM, an open or shorted TCM harness, poor electrical connection in the TCM circuit, or a faulty Powertrain Control Module (PCM). The importance of repairing this issue lies in the fact that it can affect the performance of the transmission and lead to further damage.

The repair difficulty is moderate, and the estimated repair time is around 1.0 hour. To fix this issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of u1424 fault code.

Here are the symptoms to look out for:

  • The automobile fault code u1424 has the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The automobile fault code u1424 can be caused by a faulty TCM, open or shorted TCM harness, poor electrical connection in TCM circuit, or a faulty PCM.

  • The automobile fault code u1424 can be caused by a faulty Transmission Control Module (TCM).
  • It can also be caused by an open or shorted Transmission Control Module harness.
  • Another cause can be a poor electrical connection in the Transmission Control Module circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also trigger the u1424 fault code.

To fix the u1424 fault code, check the possible causes and inspect the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code u1424, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code U1424 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the U1424 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The U1424 code is a Diagnostic Trouble Code (DTC) that indicates an issue with the engine torque signal received by the Transmission Control Module (TCM) from the Powertrain Control Module (PCM). This fault code is set when the TCM receives an implausible engine torque signal from the PCM over the Controller Area Network (CAN) Bus for a period of 1.0 second.

The TCM requests a change in the engine torque to avoid possible damage to the transmission, but if the signal received is implausible, it can cause problems and trigger the U1424 code.

What are the possible causes of the u1424 automobile fault code?

If you’re experiencing the u1424 fault code, your engine light may be on. This could be due to a faulty Transmission Control Module (TCM), an open or shorted TCM harness, a poor electrical connection in the TCM circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can one visually inspect the related wiring harness and connectors to fix the u1424 fault code?

If you’re experiencing the u1424 fault code, which is indicated by the engine light being on or the service engine soon warning light, there are a few things you can do to fix it. The possible causes include a faulty Transmission Control Module (TCM), an open or shorted TCM harness, a poor electrical connection in the TCM circuit, or a faulty Powertrain Control Module (PCM). To address these issues, you should visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.

Is a faulty Powertrain Control Module (PCM) a common cause of the u1424 fault code?

The u1424 fault code, indicated by the engine light or service engine soon warning light, can be caused by a faulty Transmission Control Module (TCM), an open or shorted TCM harness, poor electrical connection in the TCM circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, inspect the related wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

u1424 error fault code explained

If your engine light is on and the code is u1424, it may be due to a faulty Transmission Control Module (TCM), an open or shorted TCM harness, poor electrical connection in the TCM circuit, or a faulty Powertrain Control Module (PCM). Visually inspect the wiring harness and connectors for damage or corrosion.
