Intake Manifold Runner Control Circuit High Bank 1
The P2010 code indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the intake manifold runner control (IMRC) circuit for bank 1. The IMRC system uses actuators and flaps to optimize airflow into the engine at different RPMs. A high voltage reading typically points to a short to power, a faulty actuator, or a wiring issue. This can affect engine performance and fuel economy.
01. Most Common Causes
- Faulty intake manifold runner control actuator
- Short to power in the IMRC circuit wiring
- Corroded or damaged connector
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light on
- Reduced engine power or hesitation
- Poor fuel economy
- Rough idle or stalling
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to confirm P2010 and check for other codes.
Step 2: Visually inspect the IMRC actuator and wiring for damage or corrosion.
Step 3: Test the actuator resistance and compare to manufacturer specs.
Step 4: Check for shorts to power or ground in the circuit using a multimeter.
Step 5: If wiring and actuator are good, test PCM output signals.
