P2664 Dodge Code - 'B' Rocker Arm Actuator Control Circuit High Bank 2
Quick Answer
The P2664 code for Dodge vehicles refers to a 'B' Rocker Arm Actuator Control Circuit High Bank 2 issue. Common causes include Faulty Rocker Arm Actuator: A malfunctioning 'B' rocker arm actuator can cause the control circuit to operate at a high voltage, triggering the P2664 code, Wiring Issues: Damaged or corroded wiring connections related to the rocker arm actuator control circuit can lead to voltage irregularities and the code being set, Sensor Malfunction: A faulty sensor that monitors the rocker arm actuator's operation can inaccurately detect high voltage levels, causing the code to be triggered. 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 P2664 Dodge Description
The P2664 code for Dodge vehicles refers to a 'B' Rocker Arm Actuator Control Circuit High Bank 2 issue. This code indicates that there is a problem with the control circuit for the 'B' rocker arm actuator in bank 2 of the engine. The rocker arm actuator is responsible for controlling the movement of the rocker arms, which play a crucial role in the operation of the engine's valves.
Common Causes of P2664 Dodge
- Faulty Rocker Arm Actuator: A malfunctioning 'B' rocker arm actuator can cause the control circuit to operate at a high voltage, triggering the P2664 code.
- Wiring Issues: Damaged or corroded wiring connections related to the rocker arm actuator control circuit can lead to voltage irregularities and the code being set.
- Sensor Malfunction: A faulty sensor that monitors the rocker arm actuator's operation can inaccurately detect high voltage levels, causing the code to be triggered.
- Engine Computer (ECU) Malfunction: A malfunctioning Engine Control Unit (ECU) can send incorrect signals to the rocker arm actuator control circuit, resulting in high voltage readings and the P2664 code.
Symptoms of P2664 Dodge
- Check Engine Light: The most common symptom associated with the P2664 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Engine Performance: The engine may experience decreased power, acceleration, and overall performance due to the rocker arm actuator control circuit issue.
- Rough Idling: The engine may idle roughly or unevenly, causing vibrations and instability when the vehicle is stationary.
- Engine Misfires: The P2664 code can lead to engine misfires, resulting in a noticeable lack of smooth operation and potential exhaust emissions issues.
How to Fix P2664 Dodge
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code and perform a thorough inspection of the rocker arm actuator control circuit to identify the root cause of the high voltage.
- Replace Rocker Arm Actuator: If the actuator is found to be faulty, replace it with a new one to ensure proper operation of the rocker arms and valves.
- Repair Wiring Connections: Inspect and repair any damaged or corroded wiring connections in the rocker arm actuator control circuit to address voltage irregularities.
- Replace Sensor: If a faulty sensor is identified as the cause of the high voltage readings, replace it with a new sensor to ensure accurate monitoring of the rocker arm actuator.
- Reset ECU: After completing the repairs, reset the Engine Control Unit (ECU) to clear the trouble code and relearn the new parameters for the rocker arm actuator control circuit.
Cost to Fix P2664 Dodge
The typical repair costs for addressing a P2664 code on a Dodge vehicle can range from $200 to $500, depending on the specific cause of the issue and the parts and labor required for the repair. This estimate includes the cost of diagnostic testing, replacement parts, and labor charges at an auto repair shop. It's important to note that the actual repair costs may vary based on the location, vehicle make and model, and the specific repair shop's labor rates. It's advisable to consult with a qualified mechanic or technician to get an accurate estimate for resolving the P2664 code on your Dodge vehicle.
