|P0AE2 SATURN code possible causes
- Faulty Battery Energy Control Module
- Battery Energy Control Module harness is open or shorted
- Battery Energy Control Module circuit poor electrical connection
|How is the P0AE2 SATURN code repair?
Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
|What is the cost to diagnose the P0AE2 SATURN code
The cost to diagnose the P0AE2 SATURN code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
|What are P0AE2 SATURN code possible symptoms?
- Engine Light ON (or Service Engine Soon Warning Light)
|What is P0AE2 SATURN code meaning?
The hybrid/EV 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 hybrid/EV battery assembly. The 5 high voltage contactors consist of a main positive high voltage contactor, main negative high voltage contactor, charge positive high voltage contactor, charge negative high voltage contactor and multi-function high voltage contactor. 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 hybrid/EV powertrain control module 2. The hybrid/EV powertrain control module 2 supplies voltage to the control circuit for the high voltage contactors/transistors. Ground is provided through the case ground.
