Some 2013 model year FR-S vehicles may exhibit intake and/or exhaust camshaft position sensor related and/or engine misfire DTCs (P0340, P0341, P0345, P0346, P0365, P0366, P0390, P0391, P0301, P0302, P0303, and P0304) due to the camshaft position sensor clearance being out of specification. In addition, some vehicles may also experience rough idle or extended cranking. This bulletin provides inspection and repair procedures to improve this condition.
