P1017: Valvetronic Eccentric Shaft Sensor Plausibility (BMW/MINI)
6 vehicles · 1 makes · $150-$4,000 repair
Most Reported On
P1017 is an OBD-II diagnostic trouble code meaning “Valvetronic Eccentric Shaft Sensor Plausibility (BMW/MINI).” P1017 is a manufacturer-specific code (meaning varies by automaker, but most commonly BMW/MINI) that generally indicates an implausible or out-of-range signal from the Valvetronic eccentric shaft position sensor, which the engine controller uses to monitor how far the intake valves are opening. When the reported shaft position does not agree with what the computer expects, it flags this plausibility fault. Because Valvetronic controls engine airflow, the engine often drops into reduced power until the fault is fixed. This code is most commonly reported on 2008-2013 BMW M3, 2017-2024 BMW M240i, and 2009-2015 BMW 7 Series (750Li, 750i, 750iL), plus 3 other vehicles, with repair costs ranging from $150 to $4,000.

FAQ
What does P1017 mean?
P1017 stands for "Valvetronic Eccentric Shaft Sensor Plausibility (BMW/MINI)." P1017 is a manufacturer-specific code (meaning varies by automaker, but most commonly BMW/MINI) that generally indicates an implausible or out-of-range signal from the Valvetronic eccentric shaft position sensor, which the engine controller uses to monitor how far the intake valves are opening. When the reported shaft position does not agree with what the computer expects, it flags this plausibility fault. Because Valvetronic controls engine airflow, the engine often drops into reduced power until the fault is fixed.
What are the most common causes of P1017?
The most common causes of P1017 are: Engine oil leaking onto/into the eccentric shaft sensor (valve cover gasket), Faulty eccentric shaft position sensor, Wiring or connector damage at the sensor, Valvetronic motor or mechanical binding affecting position feedback, Oil contamination of the sensor connector, Control module fault (less common). The specific cause varies by vehicle.
