Q: Decreased engine power

asked by on

DIC is saying "decreased engine power." The car won't go.

A: The decreased engine power may be displayed...

The decreased engine power may be displayed for a variety of reasons, most likely there is a fuel issue or an engine misfire. In either case, the car's computer has put the vehicle into what we call "limp" mode. When a vehicle is in limp mode it has decreased engine power and may limit top speed. This is a failsafe feature to prevent further damage that may be done by continued driving. A qualified technician, such as from YourMechanic, will be able to diagnose and repair your vehicle's loss of power to get you safely back on the road.
