This summary uses the existing diagnostic information shown in full below.
Your car has a part that helps it breathe better, and it's not working right on one side of the engine.
The intake manifold runner control system adjusts the airflow in the engine to optimize performance and efficiency. Code P2012 indicates a problem with the electrical circuit controlling this system on bank 2 of the engine.
The P2012 code is triggered when the Engine Control Module (ECM) detects a low voltage condition in the intake manifold runner control circuit for bank 2. This circuit is responsible for controlling the position of the intake manifold runner valves, which manage the air entering the engine for optimal combustion.
• Check Engine Light illuminated
• Reduced engine performance
• Poor fuel economy
• Faulty intake manifold runner control actuator
• Wiring issues such as shorts or open circuits
• Faulty ECM
Intake Manifold: A component that distributes air to the engine's cylinders.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the intake manifold runner control actuator.
• Repair or replace damaged wiring or connectors.
• Replace the intake manifold runner control actuator.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance checks
• Timely repair of wiring issues
• Using quality fuel
Sensor Issue
• Have the vehicle inspected by a professional.
• Avoid heavy acceleration until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on emissions-related components.
This code is commonly associated with intake manifold runner issues in vehicles with variable intake systems.
Moderate – It should be addressed soon to avoid potential engine performance issues.
Driving with a malfunctioning intake system can lead to increased emissions and may not comply with local emissions regulations.
• Engine at operating temperature
• Idle and varying RPMs
The intake manifold runner control actuator is typically located on the intake manifold, which is on top of the engine.
Q: Can I drive with a P2012 code?
A: While the car may still be drivable, it's best to fix the issue soon to avoid reduced performance and fuel efficiency.
Q: What is bank 2?
A: Bank 2 refers to the side of the engine opposite bank 1, which is where cylinder 1 is located.
