Intake Manifold Runner Position Sensor Circuit High Bank 2
The P2022 code indicates that the Powertrain Control Module (PCM) has detected a high voltage signal from the intake manifold runner position sensor on bank 2. This sensor monitors the position of the intake manifold runner control (IMRC) flaps, which optimize airflow at different engine speeds. A high voltage reading typically points to a short to power, a faulty sensor, or a wiring issue. This can cause the IMRC system to malfunction, affecting engine performance and fuel economy.
01. Most Common Causes
- Faulty intake manifold runner position sensor
- Short to power in the sensor circuit
- Damaged wiring or connector
- Corrosion or poor electrical connection
- Failed PCM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or hesitation
- Poor fuel economy
- Rough idle or stalling
- Failed emissions test
03. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm the code and check for additional codes.
Step 2: Visually inspect the sensor and wiring for damage, corrosion, or loose connections.
Step 3: Test the sensor voltage with a multimeter; compare to manufacturer specifications.
Step 4: Check for a short to power by disconnecting the sensor and testing the circuit.
Step 5: If wiring is intact, replace the intake manifold runner position sensor.

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 engine performance and potential damage to the intake system. You may notice hesitation or poor fuel economy.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on the vehicle and shop rates. The sensor itself is often inexpensive.
