Code P1FFD Buick Description
The P1FFD Buick code indicates a problem with the Hybrid/EV battery pack coolant level sensor circuit, specifically detecting high voltage. This sensor is crucial for monitoring the coolant level in the battery pack to ensure it remains within the optimal range for cooling the batteries. If the coolant level sensor circuit is indicating high voltage, it could mean that there is a malfunction in the sensor itself, the wiring connected to it, or potentially an issue with the battery pack coolant system.
Common Causes of P1FFD Buick
- Faulty coolant level sensor
- Wiring issues in the sensor circuit
- Low coolant level in the battery pack
- Malfunctioning battery cooling system
- Electrical issues in the battery pack
Symptoms of P1FFD Buick
- Check engine light illuminated
- Battery temperature warning light
- Inconsistent battery performance
- Reduced fuel efficiency
- Overheating of the battery pack
How to Fix P1FFD Buick
- Perform a visual inspection of the coolant level sensor and its wiring for any visible damage or corrosion.
- Test the coolant level sensor using a multimeter to check for proper voltage readings.
- Check the coolant level in the battery pack and refill if necessary.
- Inspect the battery pack cooling system for any leaks or malfunctions.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.

Frequently Asked Questions about P1FFD Buick Code
What does the OBDII code P1FFD mean for a Buick?
The P1FFD code indicates an issue with the Hybrid/EV battery pack coolant level sensor circuit, specifically detecting high voltage in the sensor circuit.
What are the common symptoms of code P1FFD?
Symptoms may include an illuminated check engine light, reduced hybrid/EV performance, or warning messages related to the battery system.
What causes the P1FFD code to appear?
Potential causes include a faulty coolant level sensor, damaged wiring or connectors in the sensor circuit, or an issue with the battery pack control module.
Can I drive my Buick with the P1FFD code active?
It’s not recommended to drive for long periods with this code active, as it may indicate an issue that could lead to overheating or damage to the battery pack.
How do I diagnose the P1FFD code?
Start by inspecting the coolant level sensor, its wiring, and connectors for damage or corrosion. Use a scan tool to monitor the sensor readings and check for proper voltage and continuity.
Does the P1FFD code mean the battery pack is damaged?
Not necessarily. The code typically points to an electrical issue with the coolant level sensor circuit, not the battery pack itself.
How do I fix the P1FFD code?
Repairs may involve replacing the coolant level sensor, repairing damaged wiring or connectors, or reprogramming the battery control module if needed.
Could low coolant levels trigger the P1FFD code?
Low coolant levels might indirectly cause the code if the sensor detects a fault due to insufficient fluid, but the code specifically relates to electrical circuit issues.
What tools are needed to troubleshoot the P1FFD code?
A scan tool capable of reading hybrid/EV codes, a multimeter for checking voltages and continuity, and basic hand tools for inspecting and repairing wiring and components.
How much does it cost to fix the P1FFD code on a Buick?
Repair costs can range from $100 to $500, depending on whether the issue is a simple wiring fix, sensor replacement, or module reprogramming.
