P0018: Crankshaft/Camshaft Position Correlation - Bank 2 Sensor A
17 vehicles · 12 makes · $500-$8,500 repair
Most Reported On
P0018 is an OBD-II diagnostic trouble code meaning “Crankshaft/Camshaft Position Correlation - Bank 2 Sensor A.” This code means the computer detected that the crankshaft and the Bank 2 'A' (typically intake) camshaft are out of their expected timing relationship. The computer compares the crankshaft and camshaft position sensor signals; they should stay in a fixed correlation as the engine turns. When the Bank 2 camshaft is too far off from the crankshaft, P0018 sets, indicating the valve timing on that bank is misaligned. This can cause rough running, reduced power, hard starting, or a no-start, and in some cases signals timing chain or phaser trouble that warrants prompt attention. This code is most commonly reported on 2010-2022 Land Rover Range Rover, 2009-2015 Jaguar XF, and 2007-2015 Jaguar XK, plus 14 other vehicles, with repair costs ranging from $500 to $8,500.
