Most Reported On
P1014 is an OBD-II diagnostic trouble code meaning “Manufacturer-Specific Powertrain Code (BMW/MINI: Valvetronic Eccentric-Shaft Sensor; Domestic: Exhaust Camshaft Position Actuator).” P1014 is a manufacturer-specific powertrain code whose meaning varies by maker. On BMW and MINI it typically points to a problem with the Valvetronic eccentric-shaft position sensor or its reference position. On many domestic vehicles it relates to the exhaust camshaft position actuator (variable valve timing) being out of the expected range, and some makes such as Dodge use it for an emission solenoid circuit. Because the definition differs by brand, it should be confirmed against the specific vehicle's service data. This code is most commonly reported on 2008-2013 BMW M3, 2017-2024 BMW M240i, and 2014-2018 BMW 4 Series (435i, 440i, M440i), plus 4 other vehicles, with repair costs ranging from $150 to $4,000.
