B Rocker Arm Actuator Control Circuit High Bank 1
This code means that the computer in your car found a problem with a part that helps control how the engine's parts move. It's like if a switch that controls a toy car's wheels got stuck in the 'go fast' position.
The P2654 code indicates that the powertrain control module (PCM) has detected a high voltage condition in the rocker arm actuator control circuit for bank 1, which may affect engine performance.
The rocker arm actuator is part of the variable valve timing (VVT) system, which optimizes engine performance and efficiency. A 'high' condition in the circuit suggests that the voltage is above the expected range, potentially due to a short circuit or a faulty actuator.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the rocker arm actuator for proper function.
• Repair or replace damaged wiring or connectors.
• Replace the faulty rocker arm actuator.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Engine Performance
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic for an accurate diagnosis.
Check if the vehicle's powertrain warranty covers the rocker arm actuator.
This code is commonly reported in vehicles with aging VVT systems or those with poor maintenance history.
Moderate – It should be addressed soon to prevent potential engine damage.
Driving with this code active may lead to increased emissions and reduced engine performance.
• Engine at operating temperature
• Vehicle at idle or low speed
The rocker arm actuator is typically located on the cylinder head of the engine, near the camshaft.
Q: Can I drive with a P2654 code?
A: It's not recommended to drive with this code active, as it can lead to engine performance issues.
Q: What happens if I ignore the P2654 code?
A: Ignoring this code can lead to poor fuel economy, reduced engine performance, and potential engine damage.
