The fault code P1EC5 is a diagnostic trouble code related to the hybrid battery pack. The code indicates a malfunction in the battery pack’s cooling system. The estimated repair time for this issue is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour. Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P1EC5 code is related to the hybridEV battery pack heater transistor.

The hybridEV battery 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 2 transistors consist of the precharge transistor and heater transistor. The contactors and transistors close and open in a specific sequence controlled by the hybridEV powertrain control module 2.

The hybridEV powertrain control module 2 supplies voltage to the control circuit for the high voltage contactorstransistors.

Ground is provided through the case ground.

What are the possible causes of the P1EC5 automobile fault code?
