Common Issues It May Solve

• Rough or unstable idle caused by throttle body wear
• Throttle response problems from sensor or actuator failure
• Electronic throttle control faults related to internal component degradation
• Airflow inconsistency from carbon buildup or corrosion damage
• Driveability concerns on Chevrolet Volt and Cadillac ELR models with failing throttle control

Installation Notes and Tips

Verify connector style, inlet and outlet dimensions, and OE cross-reference before installation. The gasket or seal is not included, and mounting hardware is not included, so inspect the existing sealing surfaces and related components before reassembly. After installation, clear any stored throttle-related fault codes and perform the required throttle relearn or adaptation procedure if specified by the vehicle service information.
