This summary uses the existing diagnostic information shown in full below.
This code means that a part in the engine that helps control how the engine's valves open and close is not working properly. It's like a switch that got stuck in the 'on' position.
The P2652 code indicates that the rocker arm actuator system, which controls the movement of the engine's valves, is stuck in the 'on' position on bank 1 of the engine.
The rocker arm actuator is part of the variable valve timing (VVT) system, which optimizes the timing of the engine's valve operation. When the actuator is stuck 'on', it means that the system is not able to adjust the valve timing as needed, potentially affecting engine performance.
• Check Engine Light is on
• Reduced engine performance
• Poor fuel economy
• Faulty rocker arm actuator
• Oil flow issues to the VVT system
• Wiring problems or connector issues
Rocker Arm: A component in the engine that helps open and close the valves.
Actuator: A device that moves or controls a mechanism or system.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors to the rocker arm actuator.
• Check the oil level and quality.
• Replace the rocker arm actuator if faulty.
• Repair or replace damaged wiring or connectors.
• Perform an oil change if oil quality is poor.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord
• Acura TSX
• Honda CR-V
• Regular oil changes
• Use manufacturer-recommended oil
• Regular engine maintenance
Engine Performance
• Address the issue promptly to avoid further engine damage.
• Consult a professional mechanic if unsure about repairs.
Check with your vehicle's manufacturer for warranty coverage on engine components.
The P2652 code has been associated with vehicles using VVT systems, particularly in models from the late 2000s and early 2010s.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Ignoring this code can lead to increased emissions and potential engine damage.
• Engine at operating temperature
• Vehicle in idle or low-load conditions
The rocker arm actuator is typically located on the cylinder head of the engine.
Q: Can I drive my car with a P2652 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to engine performance issues.
Q: What happens if I ignore the P2652 code?
A: Ignoring the code can result in poor engine performance and potentially more severe engine damage over time.
