P0024 \'B\' Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)

Study Guide and Component Location Study Guide and General Description Study The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the intake camshaft. Study This system controls the intake camshaft to provide the optimal valve timing for every driving condition. Study The ECM controls the Oil Control Valve(OCV), based on the signals output from mass air flow, throttle position and engine coolant temperature. Study The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease under overall driving conditions. Study Guide and DTC Description If there is a delay between the target angle and the real angle over 5 times,ECM sets DTC P0024. Study Guide and DTC Detecting Condition Item Detecting Condition Possible Cause DTC Strategy Study • Slow response check • Poor connection • Contamination of Oil / Clog of Oil path • OCV • CVVT Enable Conditions Study • Time after | target VVT angle –VVT angle | > 6 deg(2 sec) • Time after engine start > 10 ~ 60 sec • Coolant temperature : 0~120°C • Engine oil temperature : 0~130°C • 1000 < rpm < 6600rpm Threshold value Study • Counter of delayed following target valve timing > 5 times Diagnosis Time Study • - MIL On Condition Study • 2 Driving Cycles Study Guide Specification OCV Specification Coil Resistance (Ω) 6.7 ~ 7.7 (20°C) Signal Waveform & Data Fig.1) Normal waveform of OCV & EX-CMPS at idle. Fig.2) Normal waveform of OCV & EX-CMPS at acceleration with load.
