Diagnostic trouble code (DTC) information ECM-2100

Condition

Fig 1: Identifying Fuel Pressure Sensor

Courtesy of VOLVO CARS OF NORTH AMERICA.

The engine control module (ECM) checks the signal from the fuel pressure sensor. Diagnostic trouble code (DTC) ECM-2100 is stored if the engine control module (ECM) registers that the signal from the fuel pressure sensor is too high or too low. The diagnostic trouble code (DTC) is diagnosed when the ignition is switched on or with the engine running.

For information about fuel pressure regulation, see VIDA Design and Function.
