P1EC9 Saturn Code - A/C Compressor Motor Instantaneous High Current
Quick Answer
The AC compressor function is to provide refrigerant flow in the AC refrigerant loop to help cool down the cabin, help dehumidify the air in a defrost mode and help maintain the battery temperature. Common causes include Faulty A/C Compressor Motor, A/C Compressor Motor harness is open or shorted, A/C Compressor Motor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1EC9 Saturn Description
- The customer pushes the AC button
- The HVAC control, in AUTO mode, requests the electric AC compressor on to help in cooling the cabin or removing moisture in the defrost mode
- The High Voltage Battery Thermal System requests the AC compressor on to help maintain the battery temperature
The Hybrid/EV Powertrain Control Module 2 uses values from the A/C refrigerant pressure transducers, A/C refrigerant thermistor, duct temperature sensors, ambient air temperature sensor, passenger compartment temperature sensor, evaporator temperature sensor, battery cell temperature sensors, battery coolant temperature sensors and battery coolant pumps to determine the speed at which the compressor will operate. This speed request message is sent from the Hybrid/EV Powertrain Control Module 2 to the A/C compressor control module via GM LAN message.
What are the Possible Causes of the DTC P1EC9 Saturn?
- Faulty A/C Compressor Motor
- A/C Compressor Motor harness is open or shorted
- A/C Compressor Motor circuit poor electrical connection
