Intake Manifold Runner Position Sensor Circuit Bank 2
The P2019 code indicates a malfunction in the intake manifold runner position sensor circuit for bank 2. This sensor monitors the position of the intake manifold runner control (IMRC) flaps, which adjust airflow into the engine for optimal performance. When the circuit voltage is out of range, the PCM triggers this code, often due to a faulty sensor, wiring issues, or a stuck runner.
01. Most Common Causes
- Faulty intake manifold runner position sensor
- Damaged or corroded wiring/connectors
- Carbon buildup causing stuck runner flaps
- Failed IMRC actuator
02. Symptoms You Will Notice
- Check Engine Light on
- Reduced engine power and acceleration
- Poor fuel economy
- Rough idle or hesitation
03. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P2019 is present.
Step 2: Visually inspect the sensor and wiring for damage or corrosion.
Step 3: Test sensor voltage and resistance with a multimeter.
Step 4: Check IMRC flap operation for binding or carbon buildup.
