P0018 Toyota Code - Crankshaft Position Camshaft Position Correlation Bank 2 Sensor 'A'
Quick Answer
The Engine Control Module (ECM) controls the Oil Control Valve (OCV) to regulate the intake camshaft angle. Common causes include Dirty Oil, Variable Valve Timing (VVT) sensor circuit is open or shorted, Variable Valve Timing (VVT) sensor poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
