This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with a part that helps control the supercharger, which is like a fan that helps the engine go faster. It's not getting enough power to work right.
The P25EC code indicates that the voltage in the supercharger disconnect clutch circuit is lower than expected, which could affect the supercharger's operation.
The supercharger disconnect clutch is responsible for engaging and disengaging the supercharger. When the engine control module (ECM) detects a low voltage condition in the circuit, it triggers the P25EC code. This could be due to wiring issues, a faulty clutch, or problems with the ECM itself.
• Reduced engine performance
• Check Engine Light illuminated
• Unusual noises from the engine compartment
• Faulty supercharger disconnect clutch
• Damaged or corroded wiring or connectors
• Faulty engine control module (ECM)
Supercharger: A device that increases the pressure of air entering the engine to produce more power.
ECM: Engine Control Module, the computer that controls engine functions.
• Inspect the wiring and connectors for damage or corrosion.
• Test the supercharger disconnect clutch for proper operation.
• Check the ECM for faults or errors.
• Repair or replace damaged wiring or connectors.
• Replace the faulty supercharger disconnect clutch.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Camaro
• Ford Mustang
• Dodge Challenger
• Regular maintenance checks
• Ensure electrical connections are clean and secure
• Avoid excessive engine stress
Engine Performance
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional mechanic.
• Avoid heavy acceleration until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage related to the supercharger system.
This code has been associated with vehicles equipped with superchargers, particularly those that have been modified or have high mileage.
Moderate – It affects engine performance but is not an immediate safety issue.
Driving with a malfunctioning supercharger can lead to reduced performance and potential engine damage.
• Engine at operating temperature
• Supercharger engaged
The supercharger disconnect clutch is typically located near the supercharger assembly in the engine bay.
Q: Can I drive my car with a P25EC code?
A: It's possible, but not recommended as it may lead to reduced performance and further damage.
Q: How do I reset the P25EC code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, the code will return.
