This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer detected a problem with the power supply to a part of the car, like a motor or a sensor. It's like when a toy doesn't work because the batteries are too strong.
The P2671 code is triggered when the engine control module (ECM) detects a high voltage condition in the actuator supply voltage B circuit.
The actuator supply voltage B circuit provides power to various actuators in the vehicle. If the ECM detects that the voltage in this circuit is higher than expected, it sets the P2671 code. This could be due to a short circuit, a faulty actuator, or an issue with the wiring or connectors.
• Check Engine Light is on
• Poor engine performance
• Erratic vehicle operation
• Unusual noises from the engine
• Faulty actuator
• Short circuit in the wiring
• Faulty ECM
• Corroded or damaged connectors
• Defective power supply relay
ECM: Engine Control Module
Actuator: A component that moves or controls a mechanism or system
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the actuator for proper operation.
• Check the power supply relay for faults.
• Measure the voltage in the circuit with a multimeter.
• Replace or repair damaged wiring or connectors.
• Replace the faulty actuator.
• Replace the faulty power supply relay.
• Repair or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Honda Accord
• Toyota Camry
• Ford F-150
• Regularly inspect wiring and connectors.
• Ensure actuators are functioning properly.
• Perform regular vehicle maintenance.
Electrical Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional.
• Avoid driving the vehicle until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on electrical components.
This code has been reported in vehicles with electrical issues related to actuator circuits, often due to aging components or poor maintenance.
Moderate – Should be addressed soon to avoid further damage.
Driving with a known issue can lead to unsafe driving conditions and may void warranty claims.
• Engine running
• Vehicle at operating temperature
The actuator supply voltage B circuit is typically located within the engine bay, connected to the ECM and various actuators.
Q: Can I drive my car with a P2671 code?
A: It's not recommended to drive with this code as it can lead to further damage.
Q: How do I reset the P2671 code?
A: After fixing the issue, use an OBD-II scanner to clear the code.
