Intake Manifold Runner Position Sensor Circuit High
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. 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 voltage reading typically points to a short to power, a faulty sensor, or wiring issues. 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
- Corroded terminals
- ECM internal fault (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 P2017 and check for other codes.
Step 2: Visually inspect the sensor and wiring for damage, corrosion, or loose connections.
Step 3: Test the sensor voltage signal with a multimeter; compare to manufacturer specs.
Step 4: Check for a short to power by disconnecting the sensor and measuring voltage at the harness.
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 the issue can cause reduced engine performance and potential damage to the intake manifold or engine. Short trips to a repair shop are acceptable.
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, but labor may vary.
