P1180 — Fuel Delivery System Malfunction - Low

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Generic

About P1180

P1180 is a manufacturer-specific powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1180 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1180 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The ECM sets P1180 when it detects that the fuel pressure is lower than the expected range for a given operating condition. This may be due to insufficient fuel supply, a faulty pressure sensor, or a restriction in the fuel system. If the fuel pressure remains below the required threshold for too long, engine performance and drivability issues may occur.
