Ford F-150 wrench symbol indicator illuminated on dashboard on Ford F-150

Some Ford F-150 owners report experiencing issues when the wrench symbol indicator illuminates on their dashboard, signaling potential problems related to the powertrain or all-wheel-drive system. This warning may indicate a powertrain fault, which could involve the transmission, throttle, or 4WD controls. Additionally, some owners have noted that the light may signal issues with the powertrain control module or the all-wheel-drive system itself. Problems with the electronic throttle body and its sensor are also reported as possible triggers for the wrench light. In certain instances, the icon may appear when the vehicle enters "limp home" mode, indicating specific engine or transmission issues. It is recommended that owners have their vehicles inspected by a qualified mechanic if they encounter this indicator to diagnose and resolve any underlying problems.
