1 vehicles · 1 makes · $1,500-$3,500 repair
Most Reported On
P0366 is an OBD-II diagnostic trouble code meaning “Camshaft Position Sensor "B" Circuit Range/Performance (Bank 1).” This code indicates the 'B' camshaft position sensor on Bank 1 is electrically present but its signal is out of the expected range or inconsistent with the crankshaft position signal. The PCM uses this sensor to track camshaft timing for fuel, spark, and variable valve timing control. A range/performance fault can cause rough idle, hesitation, reduced power, or hard starting. It often points to sensor or timing alignment issues rather than a fully open circuit. This code is most commonly reported on 2008-2017 Volkswagen Passat, with repair costs ranging from $1,500 to $3,500.
