Code P1180 Description

The P1180 diagnostic trouble code (DTC) indicates a Fuel Delivery System Malfunction Low. This means that the engine control module (ECM) has detected a problem with the fuel delivery system, specifically that the fuel pressure is lower than expected. The fuel delivery system is responsible for supplying the engine with the correct amount of fuel at the right pressure for optimal combustion. When this system malfunctions, it can lead to a variety of performance issues and potentially cause long-term damage to the vehicle if left unaddressed.
