Intake Manifold Runner Position Sensor Circuit High Bank 1
The P2017 code indicates that the Engine Control Module (ECM) has detected a voltage signal from the intake manifold runner position sensor that is higher than the expected range for Bank 1. This sensor monitors the position of the intake manifold runner control (IMRC) flaps, which adjust air flow into the engine for optimal performance. A high circuit voltage typically points to a short to power, a faulty sensor, or wiring issues. This can cause poor engine performance, reduced fuel economy, and potential drivability problems.
1. Most Common Causes
- Faulty intake manifold runner position sensor
- Short to voltage in sensor circuit wiring
- Corroded or damaged connector
- Failed ECM (rare)
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or hesitation
- Poor fuel economy
- Rough idle or stalling
3. Step-by-Step Diagnosis
Step 1: Use an OBD2 scanner to confirm code P2017 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 shorts to power or ground in the circuit; repair as needed.
Step 5: Replace the sensor if faulty, then clear codes and test drive.
4. 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. Short trips to a repair shop are acceptable.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and sensor replacement, depending on labor rates and parts.
