Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-2600

Condition




The engine control module (ECM) checks the signal from the fuel pressure sensor.
The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers a fault in the signal from the fuel pressure sensor.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

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.

Possible source

Signal too high
- Short-circuit to supply voltage in the signal cable
- Open-circuit in the signal cable
- Damaged fuel pressure sensor.

Signal too low
- Short-circuit to ground in the signal cable
- Damaged fuel pressure sensor.

Fault symptom[s]
- Malfunction indicator light (MIL), on
- The engine misfires.
