Diagnostic trouble code (DTC) information ECM-260A
Condition
The engine control module (ECM) checks the signal from the fuel pressure sensor.
If the Engine control module (ECM) registers that the signal from the fuel pressure sensor does not change when the fuel pump activation changes, the diagnostic trouble code is generated.
The diagnostic trouble code (DTC) can be diagnosed when the engine is running.
Substitute Value
- The fuel pressure is set to a constant.
- The control signal to the fuel pump (FP) control module is set to a calculated value.
