P2017: Intake Manifold Runner Position Sensor/Switch Circuit High Bank 1 — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
Intake Manifold Runner Position Sensor/Switch Circuit High Bank 1. Basic catalogue definition; diagnostic details have not yet been reviewed.
Affected system: Powertrain
Symptoms
- An engine warning light may come on.
- Rough running or weak acceleration can accompany the fault.
Possible causes
- A faulty bank 1 runner-position sensor or damaged sensor wiring can produce a high electrical reading.
- An actuator or linkage problem can also disturb position feedback; high voltage alone does not prove the flaps are open.
What to check
- Confirm P2017 and inspect the position sensor and wiring on bank 1.
- Compare sensor voltage with manufacturer data and check commanded versus actual runner travel.
Also written as: P2017-00, P201700 (some scan tools add the fault-type byte, e.g. -00).
