P2670 Mercury Code - Actuator Supply Voltage 'B' Circuit Low
Quick Answer
The P2670 diagnostic trouble code (DTC) for Mercury vehicles indicates an issue with the Actuator Supply Voltage 'B' Circuit being low. Common causes include Faulty actuator: The actuator itself may be malfunctioning, causing it to draw more power than usual and resulting in a low voltage condition, Wiring issues: Damaged or corroded wiring connections leading to the actuator can disrupt the voltage supply, leading to a low voltage circuit, Faulty control module: The control module responsible for regulating the voltage to the actuator may be defective, causing the voltage to drop below the specified range. 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 P2670 Mercury Description
The P2670 diagnostic trouble code (DTC) for Mercury vehicles indicates an issue with the Actuator Supply Voltage 'B' Circuit being low. This means that the power supply to a specific actuator in the vehicle is below the expected voltage level. Actuators are components that are responsible for moving or controlling various systems within the vehicle, such as the throttle body, variable valve timing solenoids, or other engine components. When the voltage to one of these actuators is below the specified range, it can lead to malfunctions in the affected system, resulting in poor performance, decreased fuel efficiency, and potential damage to the engine over time.
Common Causes of P2670 Mercury
- Faulty actuator: The actuator itself may be malfunctioning, causing it to draw more power than usual and resulting in a low voltage condition.
- Wiring issues: Damaged or corroded wiring connections leading to the actuator can disrupt the voltage supply, leading to a low voltage circuit.
- Faulty control module: The control module responsible for regulating the voltage to the actuator may be defective, causing the voltage to drop below the specified range.
- Battery or alternator issues: A weak battery or faulty alternator can result in a low voltage supply to various components in the vehicle, including actuators.
Symptoms of P2670 Mercury
- Engine misfires or rough idling: A low voltage supply to an actuator can cause irregular engine operation, leading to misfires or rough idling.
- Reduced engine power: The vehicle may experience a decrease in power output due to the actuator not receiving enough voltage to function properly.
- Check Engine Light: The illumination of the Check Engine Light on the dashboard is a common symptom of this code being triggered.
- Poor fuel economy: The vehicle may consume more fuel than usual due to inefficient operation caused by the low voltage supply to the actuator.
How to Fix P2670 Mercury
- Diagnose the issue: Use a diagnostic scanner to read the code and pinpoint the specific actuator and circuit that is experiencing the low voltage condition.
- Check wiring and connections: Inspect the wiring harness leading to the actuator for any damage, corrosion, or loose connections that may be causing the low voltage supply.
- Test the actuator: Test the actuator itself to determine if it is functioning correctly or if it needs to be replaced.
- Check the control module: Inspect the control module that regulates the voltage supply to the actuator for any faults or malfunctions.
- Replace faulty components: Replace any faulty actuators, wiring, control modules, or other components that are causing the low voltage condition.
Cost to Fix P2670 Mercury
The cost of repairing a P2670 code can vary depending on the specific cause of the issue and the labor rates of the repair shop. On average, the repair costs for this issue can range from $200 to $500, including parts and labor. However, it is essential to consider that diagnostic time and labor rates can vary based on the location, vehicle make and model, and the severity of the issue. It is recommended to consult with a qualified mechanic or auto repair shop for an accurate estimate based on your specific circumstances.
