Intake Manifold Runner Position Sensor Circuit Malfunction (Bank 1)
The P2014 code indicates a problem with the intake manifold runner position sensor or its circuit on bank 1. This sensor monitors the position of the intake manifold runner control (IMRC) flaps, which adjust airflow for optimal engine performance. A fault can cause the engine control module (ECM) to detect an incorrect voltage signal, leading to reduced engine power, poor fuel economy, and potential drivability issues.
01. Most Common Causes
- Faulty intake manifold runner position sensor
- Wiring or connector issues (open, short, corrosion)
- Carbon buildup on IMRC flaps causing mechanical binding
- Failed IMRC actuator or vacuum leak
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power and acceleration
- Poor fuel economy
- Rough idle or hesitation
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm P2014 and check for related codes.
Step 2: Visually inspect the sensor connector and wiring for damage or corrosion.
Step 3: Test the sensor voltage and resistance with a multimeter per manufacturer specs.
Step 4: Check IMRC flap operation manually or with a scan tool to ensure free movement.
Step 5: If wiring and sensor are okay, test the actuator and vacuum lines for proper function.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause reduced performance and potential engine damage if the flaps stick or break.
How much does it cost to fix?▼
Repair costs typically range from $50 to $150 for sensor replacement, but can be higher if wiring repairs or intake manifold cleaning is needed.
