Intake Manifold Runner Control Circuit High Bank 2
Diagnostic trouble code P2013 indicates that the powertrain control module (PCM) has detected a high electrical voltage signal in the intake manifold runner control (IMRC) circuit for Bank 2. This typically means the circuit is shorted to voltage or the actuator is stuck, preventing the PCM from properly controlling the airflow through the intake manifold on the side of the engine opposite cylinder 1.
While not usually an immediate safety hazard, this code can cause poor engine performance, reduced fuel economy, and increased emissions. It should be diagnosed and repaired soon to prevent potential long-term engine or catalytic converter issues.
Common symptoms
- Illuminated Check Engine Light
- Rough idle or engine hesitation
- Reduced engine power, especially at lower RPMs
- Decreased fuel efficiency
- Engine surging or stalling
Likely causes
- Faulty intake manifold runner control (IMRC) actuator/solenoid on Bank 2
- Short to voltage in the IMRC circuit wiring or connectors
- Carbon buildup or physical binding of the intake manifold runner flaps
- Vacuum leak in the IMRC system (if vacuum operated)
- Poor electrical connection at the IMRC actuator
- Faulty Powertrain Control Module (PCM) (rare)
What to check before replacing parts
Scan for additional codes and record freeze frame data.
Look for: Check if other IMRC, vacuum, or electrical codes are present, which could indicate a shared circuit issue or a broader system failure.
Visually inspect the IMRC actuator, wiring, and connectors for Bank 2.
Look for: Look for frayed wires, melted insulation, corroded pins, or disconnected harnesses that could cause a short to voltage.
Test the IMRC actuator circuit voltage using a digital multimeter.
Look for: Check for constant high voltage on the control circuit when it should be low or fluctuating, indicating a short to power.
Manually operate the intake manifold runner flaps (if accessible).
Look for: Feel for physical binding, sticking, or excessive resistance caused by carbon buildup or mechanical failure of the linkage.
Command the IMRC actuator using a bi-directional scan tool.
Look for: Observe if the actuator moves smoothly and if the position sensor feedback matches the commanded state; lack of movement or incorrect feedback confirms a faulty actuator or mechanical bind.
