Abstract
Methods are provided for reliably self-testing a water injection system that injects water into the engine responsive to engine operating conditions such as knock, the water injection system refilled manually or via the collection of water on-board the vehicle. Responsive to a water injection error, learned based on a change in a defined set of engine parameters while ramping water injection during selected conditions, the presence of clogging in a water line may be determined. Based on a degree of clogging, subsequent water injection may be appropriately adjusted.
