EC-178 < DTC/CIRCUIT DIAGNOSIS > [HR16DE] P0075 IVT CONTROL SOLENOID VALVE 3. Check the continuity between intake valve timing control solenoid valve harness connector and ECM har- ness connector. 4. Also check harness for short to ground and short to power. YES >> GO TO 4. NO >> Repair open circuit or short to ground or short to power in harness or connectors. 4. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE EC-178, "Component Inspection" Is the inspection result normal? YES >> GO TO 5. NO >> Replace intake valve timing control solenoid valve. Refer to . 5. CHECK INTERMITTENT INCIDENT GI-41, "Intermittent Incident" >> INSPECTION END Component Inspection INFOID:0000000009020692 1. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I 1. Turn ignition switch OFF. 2. Disconnect intake valve timing control solenoid valve harness connector. 3. Check resistance between intake valve timing control solenoid valve terminals as follows. Is the inspection result normal? YES >> GO TO 2. NO >> Replace intake valve timing control solenoid valve. Refer to 2. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II 1. Remove intake valve timing control solenoid valve. Refer to 2. Apply 12 V between intake valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Make sure that the plunger moves as shown in the figure. CAUTION: Do not apply 12 V continuously for 5 seconds or more. Doing so may result in damage to the coil in intake valve timing control solenoid valve. NOTE: Always replace O-ring when intake valve timing control solenoid valve is removed. Is the inspection result normal? YES >> INSPECTION END NO >> Replace intake valve timing control solenoid valve. Refer to .
