2003 Volvo V70 2.4 L5-2.4L VIN 61 B5244SSECTION Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code (DTC) information ECM-4308
Condition
The engine control module (ECM) checks the pressure in the fuel tank by measuring the current through the leak diagnostic pump.
The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers that the pressure is not within certain limits. The engine control module (ECM) interprets this as leakage in the fuel system.
The diagnostic trouble code (DTC) can be diagnosed when the leak diagnostic system is run.
Substitute value
- None.
Possible source
Major leak
- The fuel tank filler cap is not correctly tightened
- Leaking fuel tank, fuel filler pipe, fuel tank filler cap, EVAP canister, leak diagnostic pump, evaporative emission system (EVAP) valve, or in the hoses between these components
