Code P1581 Ford Description

The P1581 Ford code indicates an Electronic Throttle Monitor Malfunction. This means that there is an issue with the electronic throttle control system in the vehicle. The electronic throttle control system, also known as drive-by-wire, is responsible for controlling the throttle opening electronically rather than through a traditional cable. This system uses sensors, such as the throttle position sensor, to communicate with the engine control module (ECM) and adjust the throttle opening accordingly.
