P1349 on 2007-2009 Jaguar XK (XK, XKR) — Variable Valve Timing System Malfunction (Bank 1)
1 vehicles · 1 makes · $600-$2,500 repair
Most Reported On
P1349 is an OBD-II diagnostic trouble code meaning “Variable Valve Timing System Malfunction (Bank 1).” A Toyota/Lexus-specific code set when the ECM commands a change in intake camshaft timing and the actual valve timing does not change, or stays fixed. The VVT system routes oil pressure through the oil control valve (OCV) to the VVT controller to shift cam position relative to the crank. Symptoms are typically rough or unstable idle, reduced power, poor fuel economy, and a check engine light. Other manufacturers use P1349 for entirely different faults — on Honda/Acura it is generally described as a VTEC system fault, and some references list unrelated definitions — so confirm against your make. This code is most commonly reported on 2007-2009 Jaguar XK (XK, XKR), with repair costs ranging from $600 to $2,500.
