Hi. WHen the wrench light comes on it means that there is a problem with the electronic throttle body of the engine. The throttle bodies are common on their own to need replacing. But I would disconnect the air intake hose to the throttle body and inspect to make sure nothing got sucked up. You also want to make sure the air filter and mass air flow sensor (which is located after the air filter in the air intake tube) is clean and has no debris on it. If all that visually looks good you likely need a new throttle body.
