P0017: Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B
138 vehicles · 35 makes · $100-$25,000 repair
Most Reported On
P0017 is an OBD-II diagnostic trouble code meaning “Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B.” This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other. The computer compares the crankshaft position signal to the camshaft position signal, and when they don't line up within the allowed window, it sets this correlation code. This usually points to mechanical timing being off, most often from a stretched or worn timing chain, a slipped or stuck variable valve timing phaser, or a tensioner problem. You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. This code is most commonly reported on 2008-2014 Volkswagen Golf (GTI, GTI Autobahn, GTI S, GTI SE, Golf R, R, R32), 2007-2013 MINI Cooper S (John Cooper Works, S), and 2012-2016 Honda CR-V, plus 135 other vehicles, with repair costs ranging from $100 to $25,000.
