DEF: Component in poor condition
NOTESPriorities when dealing with a combination of faults:
First deal with:
– DF398 – "Fuel system functional failure"
Conditions for application to a stored fault:
The fault is declared present with the engine running at an engine speed of 2500 rpm
for 10 seconds.
Special note:
OBD warning light comes on.
Check the value of parameter PR139 Operating richness adaptive.
If the value of PR139 < 1 then:
Check the sealing of the fuel supply system from the fuel pump to the injector rail:
– The fuel tank (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430
(Clio II F 6), Mechanical, 19C, Tank, Fuel tank: Removal - Refitting)
– The connection between the fuel pump and the fuel filter (see MR 388 (Logan and Sandero) Mechanical, 19C,
