P0075 Intake Valve Control Solenoid Circuit (Bank 1)

Component Location P0075 Intake Valve Control Solenoid Circuit (Bank 1)     Study Guide and Component Location Study and General Description Study Guide 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. Study 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. DTC Description When ECM detects open in the OCV(Bank 1-IN) control circuit, ECM sets DTC P0075. DTC Detecting Condition Item Detecting Condition Possible Cause DTC Strategy • Circuit continuity check, open • Poor Connection • Open or Short to ground in power circuit • Open in control circuit • OCV Enable Conditions • - Threshold value • Open Diagnosis Time • Continuous MIL On Condition • 2 Driving Cycles Specification ITEM Specification Resistance (Ω) 6.7 ~ 7.7 at 20°C(68°F) Diagnostic Circuit Diagram Signal Waveform & Data Fig.1) Normal waveform of OCV at idle.
