What is OBD-II Code P2660 – B Rocker Arm Actuator Control Circuit/Open Bank 2
If you own a car, chances are you’ve encountered an illuminated “check engine” light at some point. In many cases, this light indicates that your vehicle’s On-Board Diagnostic (OBD-II) system has detected a fault or issue that needs attention. One such fault code is OBD-II Code P2660 – B Rocker Arm Actuator Control Circuit/Open Bank 2. In this article, we will explain what this code means and how to repair the issue.
What is OBD-II Code P2660 – B Rocker Arm Actuator Control Circuit/Open Bank 2
OBD-II Code P2660 – B Rocker Arm Actuator Control Circuit/Open Bank 2 is a diagnostic trouble code that indicates a malfunction in the engine control system. Specifically, it relates to the rocker arm actuator control circuit, which is responsible for controlling the intake and exhaust valves on one bank of cylinders in the engine.
The rocker arm actuator system is a variable valve timing (VVT) system that helps improve engine performance and fuel efficiency by adjusting the timing of the engine’s intake and exhaust valves based on driving conditions. The B rocker arm actuator control circuit is one of several circuits that control the VVT system.
When the OBD-II system detects a fault in the B rocker arm actuator control circuit, it will set OBD-II Code P2660. This fault may be due to a number of issues, including a damaged or disconnected wire in the circuit, a faulty rocker arm actuator control solenoid, or a malfunctioning engine control module (ECM).
Symptoms of OBD-II Code P2660 – B Rocker Arm Actuator Control Circuit/Open Bank 2
One of the primary symptoms of OBD-II Code P2660 is an illuminated “check engine” light on the dashboard. Additionally, your vehicle may experience a number of noticeable symptoms, including:
• Reduced engine performance
• Rough idling or stalling
• Poor fuel economy
• Engine knocking or pinging
• Increased emissions levels
It’s important to address these symptoms promptly to avoid further damage to your vehicle’s engine and to ensure it is operating at peak performance.
How to diagnose OBD-II Code P2660 – B Rocker Arm Actuator Control Circuit/Open Bank 2
Diagnosing OBD-II Code P2660 will typically involve a thorough inspection of the rocker arm actuator control circuit and related components. The following is a step-by-step diagnostic process that a mechanic might use to diagnose this code:
1. Inspect the circuit: The mechanic will inspect the B rocker arm actuator control circuit for any damage or disconnection, paying close attention to the wires and connectors.
2. Test the solenoid: The mechanic will test the rocker arm actuator control solenoid to ensure it is functioning properly. This may involve using a multimeter to check the resistance of the solenoid or applying power directly to the solenoid to observe its behavior.
3. Check the engine control module: If the circuit and solenoid appear to be functioning properly, the mechanic will check the engine control module for any faults or malfunctions.
Depending on the results of these tests, the mechanic may replace damaged or faulty components, repair damaged wiring, or replace the entire engine control module.
How to repair OBD-II Code P2660 – B Rocker Arm Actuator Control Circuit/Open Bank 2
Once the cause of OBD-II Code P2660 has been diagnosed, the mechanic will typically make repairs as necessary to address the issue. The following are some potential repair options:
1. Repair damaged wiring: If the inspection reveals damage or disconnection in the circuit wiring, the mechanic may need to repair or replace the damaged wiring or connectors to restore proper operation.
2. Replace the solenoid: If the rocker arm actuator control solenoid is found to be faulty, the mechanic may need to replace it with a new solenoid to restore proper function.
3. Replace the engine control module: If the engine control module is found to be at fault, the mechanic may need to replace the entire module to restore proper function.
In some cases, a combination of the above repairs may be necessary to fully address the issue.
