What is the OBD II fault code p0251?
OBD II fault code P0251 is a generic code that is defined as “Injection pump A, rotor/cam -circuit malfunction”, and is set when the PCM (Powertrain Control Module) detects a loss of continuity, or a general failure in the signal/feedback circuits between itself, the fuel metering control sensor, the fuel quantity actuator, and other sensors
How does the p0251 injection pump fuel metering control a malfunction?
It also looks at the voltage signal from the FRP sensor to determine if it is correct at initial Key On. The code P0251 Injection Pump Fuel Metering Control A Malfunction (Cam/Rotor/Injector) could have been set because of mechanical (typically EVAP system mechanical issues) or electrical (FRP sensor circuit) issues.
When does the p0251 warning light come on?
On some applications, code P0251 will set and a warning light be triggered after a single failure, while on others, several failure cycles are required before the code is set and warning light is illuminated. Where is the P0251 sensor located? The image above shows a simplified schematic of a typical fuel pressure control system.
What are the fault codes for the Mitsubishi Fuso Fighter 6M60?
Output from the PTO accelerator position sensor is too high. Boost pressure is excessive or insufficient. Output from the intake air pressure sensor is too low. Output from the intake air pressure sensor is too high. Fuel leak in the injection system or fuel system. Pressure limiter is operating.
