This summary uses the existing diagnostic information shown in full below.
Your car has a part that helps control how air goes into the engine, and it's not getting enough power to work properly on one side of the engine.
The Intake Manifold Runner Control (IMRC) system helps manage the airflow into the engine for better performance. This code indicates that the actuator controlling this system is not receiving enough voltage on bank 2, which is the side of the engine with the second cylinder.
The P201C code is triggered when the Engine Control Module (ECM) detects a low voltage condition in the circuit that supplies power to the Intake Manifold Runner Control actuator on bank 2. This actuator is responsible for adjusting the position of the intake manifold runners to optimize engine performance and efficiency.
• Check Engine Light illuminated
• Reduced engine performance
• Poor fuel economy
• Faulty IMRC actuator
• Wiring issues such as damaged wires or poor connections
• Faulty ECM
Intake Manifold: A component that distributes air to the engine cylinders.
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 for damage or poor connections.
• Test the voltage supply to the IMRC actuator.
• Repair or replace damaged wiring or connectors.
• Replace the faulty IMRC actuator.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Ford F-150
• Chevrolet Silverado
• Dodge Ram 1500
• Regular maintenance checks
• Inspect wiring for damage periodically
• Keep the engine clean to prevent debris buildup
Engine Performance
• Avoid heavy acceleration until the issue is resolved.
• Have the vehicle checked by a professional mechanic.
Check with your vehicle manufacturer for specific warranty coverage related to engine components.
This code has been associated with issues in vehicles with complex intake systems, particularly those with variable intake manifolds.
Moderate – It should be addressed soon to prevent further engine performance issues.
Driving with this issue can lead to increased emissions and reduced engine performance, which may not comply with local emissions regulations.
• Engine running
• Electrical system active
The IMRC actuator is typically located on the intake manifold, near the top of the engine.
Q: Can I drive with a P201C code?
A: While you can drive with this code, it's not recommended as it can lead to reduced engine performance and efficiency.
Q: How can I prevent this code from appearing?
A: Regular maintenance and inspections of the intake system and electrical connections can help prevent this issue.
