[SOLVED] P3055 Code: How To Fix Dc/Dc Converter Voltage Performance

The P3055 fault code in automobiles indicates a problem with the power supply transformer.

The most common symptom is the illumination of the engine light or service engine soon warning light. The cause of this issue could be a faulty power supply transformer, an open or shorted harness, or a poor electrical connection in the power supply transformer circuit. The importance of repairing this issue lies in the fact that it can lead to further damage to the vehicle’s electrical system.

The repair difficulty is moderate, and it takes approximately 1.0 hour to fix. To fix the problem, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

  • It is important to address these symptoms promptly to avoid further damage to the vehicle and ensure safe driving.

The automobile fault code P3055 can be caused by a faulty power supply transformer, an open or shorted harness, or poor electrical connection.

  • The automobile fault code P3055 can be caused by a faulty power supply transformer.
  • It can also be caused by an open or shorted power supply transformer harness.
  • Additionally, a poor electrical connection in the power supply transformer circuit can also trigger this fault code.

To fix the p3055 automobile fault code, check the possible causes and inspect the related wiring harness, connectors, and components for damage.

  • To fix the automobile fault code p3055, you need to check the possible causes listed above.
  • 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 P3055 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of fixing the P3055 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P3055 code relates to the DCDC Converter Actuator Voltage 1 Performa. The Power Supply Transformer boosts battery voltage to sensitive loads during engine restart. The Power Supply Transformer communicates with the Engine Control Module (ECM) and passes through voltage from the two supply circuits when the engine is not cranking.

The ECM receives data about the sensed output voltages provided by the Power Supply Transformer.

What are the possible causes of the P3055 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P3055 fault code. This code is caused by a faulty power supply transformer, an open or shorted harness, or a poor electrical connection in the power supply transformer circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

How can one visually inspect the related wiring harness and connectors to fix the P3055 fault code?
