Diagnostic trouble code (DTC) information ECM-2A00
Condition
The engine control module (ECM) checks the signal from the fuel temperature sensor. The fuel temperature sensor is integrated in the fuel pressure sensor. The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers that the signal from the fuel temperature sensor is incorrect.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.
For information about fuel pressure regulation, see VIDA Design and Function. Requires Volvo scan tool.
