2011  G 4.6 DOHC Engine  Engine Control  P0085 Exhaust Valve Control Solenoid Circuit Low (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, Study 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 Study When ECM detects short to ground in OCV(Bank 2-EX) control circuit, ECM sets DTC P0085.

P0030 HO2S Heater Control Circuit (Bank 1 / Sensor 1)

Study Guide and Component Location Study Guide and General Description Study The normal operating temperature of the HO2S(Heated Oxygen Sensor) ranges from 350 to 850°C(662 to 1562°F). Study The HO2S heater greatly decreases the amount of time required for fuel control to become active. The ECM provides a pulse width modulated control circuit to adjust current through the heater. Study When the HO2S is cold, the value of the resistance is low and the current in the circuit is high. On the contrary, if the temperature in the resistor of the sensor rises, the current drops gradually. Study Guide and DTC Description Study When ECM detects open in the heater control circuit(B1S1), ECM sets DTC P0030.

Study Preheating is necessary for HO2S normal operation. Study Therefore heater unit is installed in HO2S, ECM can control air/fuel ratio with the output signal of HO2S simultaneous with engine run by reducing preheating time. Study ECM controls heater with duty cycle. Study HO2S' power source is main relay and ECM operates heater by ground control.
