If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1ec3 fault code. Here are the symptoms to look out for:

  • The P1EC3 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, poor acceleration, rough idling, stalling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience difficulty starting or fail to start altogether.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P1EC3 fault code can be caused by a faulty Battery Energy Control Module, open or shorted harness, or poor electrical connection.

  • The automobile fault code P1EC3 can be caused by a faulty Battery Energy Control Module.
  • It can also be caused by an open or shorted Battery Energy Control Module harness.
  • Additionally, a poor electrical connection in the Battery Energy Control Module circuit can also trigger this fault code.

To fix the p1ec3 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1ec3, 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 P1EC3 has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the cost of fixing the P1EC3 fault code will depend on the hourly rate charged by the repair shop.

It is important to consider this factor when budgeting for the repair of this fault code.

The P1EC3 code refers to a problem with the control circuit for the heater transistor in the hybridEV battery pack. The hybridEV battery pack contains 5 high voltage contactors and 2 transistors. The high voltage contactors and transistors allow the high voltage DC batteries to be connected to the vehicle or safely contain the high voltage DC within the hybridEV battery assembly.

The hybridEV powertrain control module 2 controls the sequence in which the contactors and transistors close and open.

The control circuit for the high voltage contactorstransistors is supplied with voltage by the hybridEV powertrain control module 2, and ground is provided through the case ground.

What are the possible causes of the P1EC3 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1EC3 fault code. This code is caused by a faulty Battery Energy Control Module, an open or shorted harness, or poor electrical connection in the 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’s pins.
