P0008: Engine Position System Performance - Bank 1
21 vehicles · 11 makes · $200-$12,000 repair
Most Reported On
P0008 is an OBD-II diagnostic trouble code meaning “Engine Position System Performance - Bank 1.” P0008 means the engine computer detected that Bank 1 of the engine is timed incorrectly relative to where it should be — specifically, the relationship between the crankshaft and camshaft positions on that bank is off. The 'Engine Position System' refers to the components (timing chain/belt, sprockets, tensioners, and the variable valve timing actuators) that keep the camshafts synchronized with the crankshaft. When the computer commands a timing position but the sensors report the bank is out of the expected range, it sets this code. It generally signals a mechanical timing problem on Bank 1 that can affect performance and, if severe, risk internal engine damage. This code is most commonly reported on 2013-2019 Mercedes-Benz B-Class (B180, B200, B220, B250), 2006-2014 Opel Corsa (Selection, Edition, Cosmo, Color Edition), and 2009-2018 Opel Astra (Selection, Edition, Cosmo, Sport, 120 Jahre), plus 18 other vehicles, with repair costs ranging from $200 to $12,000.
