Abstract
Systems and methods for performing closed-in-bore diagnostics for a hybrid vehicle are presented. In one example, select operating conditions may be evaluated before closed-in-bore diagnostics may be initiated. In addition, charging of one or more batteries may be reduced to ensure that an engine throttle may operate with a small opening amount to evaluate the presence or absence of sludge in the engine throttle.
