Code P1FE5 Saturn Description
The battery energy control module monitors the voltage of the 96 battery cell groups. The voltage sense lines are attached to each individual cell group, and these sense lines terminate at a connector located on the top surface of the battery section. A voltage sense harness joins this connector to the battery energy control module.
The battery energy control module contains internal interface control modules that monitor specific cell groups.
The battery energy control module will determine when a fault condition is present. Diagnostics and system status are communicated from the battery energy control module to the hybrid powertrain control module 2 through serial data. The hybrid powertrain control module 2 is the host controller for diagnostic trouble code information.
What are the Possible Causes of the DTC P1FE5 Saturn?
- Faulty Hybrid/EV Battery Interface Control Module
- Hybrid/EV Battery Interface Control Module harness is open or shorted
- Hybrid/EV Battery Interface Control Module circuit poor electrical connection

What are the common symptoms of P1FE5 in a Saturn?
Symptoms may include an illuminated check engine light, reduced hybrid/EV performance, limited battery charging, or warning messages on the dashboard.
What causes the P1FE5 code to trigger?
Potential causes include a faulty voltage sensor, damaged wiring or connectors, a malfunctioning battery interface control module, or a software issue in the control module.
How can I diagnose the P1FE5 code on my Saturn?
Diagnosis typically involves scanning the vehicle with an OBDII tool, inspecting the voltage sensor and related wiring, and testing the Hybrid/EV Battery Interface Control Module for proper operation.
Can I continue driving my Saturn with the P1FE5 code active?
While the vehicle may still function, driving with this code active could lead to reduced performance or further damage to the hybrid/EV system. It’s best to address the issue promptly.
How is the P1FE5 code fixed?
Repairs may involve replacing the faulty voltage sensor, repairing damaged wiring or connectors, reprogramming the control module, or replacing the Hybrid/EV Battery Interface Control Module if necessary.
How much does it cost to fix the P1FE5 code on a Saturn?
Repair costs can vary widely, ranging from $100 for sensor or wiring repairs to over $1,000 for control module replacement, depending on the exact issue and labor rates.
Is the P1FE5 code covered under warranty for my Saturn?
Hybrid/EV battery and control module components may still be covered under a warranty, especially if the vehicle is within the manufacturer’s hybrid warranty period. Check with your dealership.
Can a low auxiliary battery cause the P1FE5 code?
While less common, a low or failing 12V auxiliary battery might contribute to voltage irregularities. It’s worth checking the auxiliary battery as part of the diagnosis.
Should I clear the P1FE5 code after repairs?
Yes, after completing repairs, clear the code with a scan tool and test drive the vehicle to ensure the issue does not reoccur.
