Intake Manifold Runner Control Circuit High Bank 2
The P2013 code indicates that the Powertrain Control Module (PCM) has detected a high voltage signal from the intake manifold runner control (IMRC) circuit on bank 2. This typically means the IMRC actuator or its wiring has a short to voltage or an internal fault. The IMRC system adjusts runner length to optimize airflow at different RPMs; a fault can reduce engine performance and fuel economy.
1. Most Common Causes
- Short to voltage in the IMRC actuator wiring
- Corroded or bent pins in the sensor/actuator electrical connector
- Internally damaged intake manifold runner control solenoid or actuator
- Mechanical binding of the intake manifold runner valves preventing movement
- Faulty powertrain control module (PCM) (uncommon)
2. Symptoms You Will Notice
- Check Engine Light on
- Reduced engine power and acceleration
- Poor fuel economy
- Rough idle or hesitation
3. Step-by-Step Diagnosis
Step 1: Use a scan tool to confirm P2013 and check for other codes.
Step 2: Visually inspect the IMRC actuator and wiring for damage or corrosion.
Step 3: Test the IMRC actuator resistance and supply voltage with a multimeter.
Step 4: Check for shorts to ground or voltage in the circuit.
Step 5: Replace the IMRC actuator if faulty, or repair wiring as needed.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is generally safe for short trips, but you may experience reduced performance and fuel economy. Prolonged driving could cause further issues, so it's best to diagnose and repair promptly.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on whether it's a simple wiring repair or actuator replacement.
