P3052 fault code can be caused by a faulty power supply transformer, open or shorted harness, or poor electrical connection.

  • The automobile fault code P3052 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.

Below are the possible fixes for the automobile fault code p3052, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p3052, 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 P3052 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 P3052 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 P3052 code refers to a problem with the DCDC Converter Actuator Voltage Sensor Circuit 2. This circuit is responsible for monitoring the voltage output of the Power Supply Transformer. If the voltage is too low, the Engine Control Module (ECM) will trigger the P3052 code.

This can cause issues with sensitive loads during engine restart and should be addressed promptly to avoid further damage.
