P115A — Low Fuel Level – Forced Limited Power

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

About P115A

P115A is a manufacturer-specific powertrain diagnostic trouble code recorded for Ford vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P115A 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.

P115A 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

On these Ford vehicles the Powertrain Control Module (PCM) monitors the fuel level signal from the fuel level sensor, usually part of the fuel pump module in the tank. DTC P115A sets when the PCM sees a persistently low fuel level below a calibrated threshold and applies a protective forced limited power strategy. This power limiting is designed to prevent fuel starvation under high load and to protect components such as the high pressure fuel pump and injectors from running dry. The code can simply reflect a genuinely low fuel level, or a fuel level sensor or circuit fault reporting low when ...
