Common Diagnostic Steps

OBD2 Code: P0076

Description: Intake Valve Control Solenoid Circuit Low Bank 1

• Check the intake valve control solenoid for proper operation and resistance.
• Inspect the wiring and connectors for damage, corrosion, or disconnection.
• Test the power supply to the solenoid from the engine control module (ECM).
• Verify that there is no blockage in the oil passages affecting solenoid function.
• Use a scan tool to monitor live data and confirm if the solenoid is receiving correct signals.
• If necessary, replace the intake valve control solenoid with a new one.
