P1F0D Saturn Code - Electric A/C Compressor Control Module A/C Compressor Motor Current Feedback Circuit High Voltage
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, A/C Compressor harness is open or shorted, A/C Compressor 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 P1F0D 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 message is sent from the Hybrid/EV Powertrain Control Module 2 to the A/C compressor control module via serial data message.
AC Compressor has a motor start up procedure that can take a variable length of time to run to bring the motor up to requested speed. Length of time is dependent on external conditions such as under-bonnet temperature and high side pressure. In hotter conditions, the motor start up time will be longer. The A/C compressor control module monitors an internal parameter known as the DC link current which is based off DC input current. It is not possible to measure this parameter externally.
What are the Possible Causes of the DTC P1F0D Saturn?
- Faulty A/C Compressor
- A/C Compressor harness is open or shorted
- A/C Compressor circuit poor electrical connection
How to Fix the DTC P1F0D Saturn?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?

Frequently Asked Questions about P1F0D Saturn Code
1. What does the OBDII code P1F0D mean in a Saturn vehicle?
P1F0D indicates an issue with the Electric A/C Compressor Control Module, specifically that the A/C compressor motor current feedback circuit is detecting high voltage.
2. What are the common symptoms of the P1F0D code in a Saturn?
Symptoms may include the A/C system not functioning properly, reduced cooling performance, illuminated check engine light, and unusual noises from the compressor.
3. What causes the P1F0D code to appear?
This code can be triggered by a faulty A/C compressor control module, damaged wiring or connectors, a short circuit, or an internal failure in the A/C compressor motor.
4. Can I continue driving with the P1F0D code active?
While the vehicle may still be drivable, it’s advisable to address the issue promptly to avoid further damage to the A/C system or related electrical components.
5. How is the P1F0D code diagnosed?
A technician will use a scan tool to confirm the code, inspect the A/C compressor control module and wiring, and test for high voltage or electrical shorts in the feedback circuit.
6. How do you fix the P1F0D code on a Saturn?
Repairs may involve replacing the A/C compressor control module, fixing damaged wiring or connectors, or replacing the A/C compressor if it has an internal failure.
7. Can a blown fuse cause the P1F0D code?
Yes, a blown fuse in the A/C compressor circuit can contribute to the issue, though it’s more commonly associated with wiring or module problems.
8. What tools are needed to troubleshoot the P1F0D code?
You’ll need an OBDII scanner, a digital multimeter for electrical testing, and possibly wiring diagrams to trace the circuit.
9. How much does it cost to fix the P1F0D code?
The repair cost can vary widely, from $100 for minor wiring repairs to over $1,000 if the A/C compressor or control module needs replacement.
10. Can I fix the P1F0D code myself?
If you have experience with electrical diagnostics and access to the right tools, you may be able to fix simple issues like damaged wiring. For more complex problems, professional help is recommended.
