Code P0011 Honda Description

The Variable Valve Timing Control (VTC) system controls the phase of the intake camshaft and exhaust camshaft. It uses oil pressure to operate the VTC actuator A/B so the valve timing is optimized depending on driving conditions. The Powertrain Control Module (PCM) monitors the phase control command and the actual phase of the intake camshaft by using Camshaft Position (CMP) sensor 'A'. If the phase difference between them is excessive for a certain time period, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
