[SOLVED] U1403 Code: Fixing Fuel Level Signal For Smooth Driving

The automobile fault code U1403 indicates a problem with the Powertrain Control Module (PCM) or Body Control Module (BCM). 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 PCM, open or shorted PCM harness, poor electrical connection in the PCM circuit, or a faulty BCM. The importance of repairing this issue lies in the fact that it can affect the performance of the vehicle.

The repair difficulty is moderate, and the repair time is estimated to be around 1.0 hour.

To fix the issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins. It is essential to interpret the fault code correctly to ensure the proper repair of the vehicle.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of u1403 fault code. Here are the symptoms to look out for:

  • The U1403 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON, issues with the transmission, problems with the speedometer, issues with the cruise control, and problems with the anti-lock brake system.
  • It can also cause the vehicle to shift harshly or erratically, and may result in decreased fuel efficiency.
  • If you experience any of these symptoms, it is important to have your vehicle diagnosed and repaired by a qualified mechanic as soon as possible to prevent further damage.

The automobile fault code u1403 can be caused by a faulty PCM, BCM, or poor electrical connections.

  • The automobile fault code u1403 can be caused by a faulty Powertrain Control Module (PCM).
  • It can also be caused by an open or shorted Powertrain Control Module harness.
  • Another cause can be a poor electrical connection in the Powertrain Control Module circuit.
  • Lastly, a faulty Body Control Module (BCM) can also trigger the u1403 fault code.

To fix the u1403 automobile fault code, check the possible causes and inspect the related wiring harness, connectors, and components for damage.

  • To fix the automobile fault code u1403, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 U1403 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 diagnosing and fixing the U1403 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 U1403 code is related to the fuel level sensor signal in the automobile. The Body Control Module (BCM) receives the fuel level signal and transmits it to the Powertrain Control Module (PCM) over the Controller Area Network (CAN) C bus. The U1403 code sets when the fuel level message received by the PCM is implausible, and the circuit is continuously monitored.

What are the possible causes of the u1403 automobile fault code?

If you’re experiencing the u1403 fault code, your engine light may be on. This could be due to a faulty Powertrain Control Module (PCM), an open or shorted PCM harness, a poor electrical connection in the PCM circuit, or a faulty Body Control Module (BCM). 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 u1403 fault code?

If you’re experiencing the u1403 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few things you can do to fix it. The possible causes include a faulty Powertrain Control Module (PCM), an open or shorted Powertrain Control Module harness, a poor electrical connection in the Powertrain Control Module circuit, or a faulty Body Control Module (BCM). 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’s pins.

What are the consequences of ignoring the u1403 fault code?

Ignoring the u1403 fault code can lead to serious consequences such as reduced fuel efficiency, engine misfires, and even engine failure. The fault code is usually caused by a faulty Powertrain Control Module (PCM), an open or shorted PCM harness, poor electrical connection in the PCM circuit, or a faulty Body Control Module (BCM). To fix the issue, it is important to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
