Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CEM-P046015

Condition
The Central electronic module (CEM) checks the direct current (DC) the fuel level sensor on the fuel pump.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Direct current (DC) from the fuel level sensor is higher than 4.5 V.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position I and II.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- The fuel level is set to zero.

Possible source
- Open-circuit in the fuel level sensor (right-hand side) or short-circuit to battery voltage.

Fault symptom[s]
- Trip computer indicates too early that fuel tank is empty
- Displays faulty fuel level
