Code P1354 Toyota Highlander 2001 6cl. missfiering 2,4,6 when hot planning to replace Oil Conrol Valve at passenger side

Code P1354 indicates a camshaft position sensor or oil control valve (OCV) issue affecting cylinders 2, 4, and 6 misfires when the engine is hot. Start by inspecting and replacing the passenger side OCV, which controls variable valve timing. Check wiring and connectors for damage or corrosion. Cleaning or replacing the OCV can restore proper oil flow to the camshaft phasers, resolving misfires. Regular oil changes help prevent OCV clogging and maintain engine timing performance.
