PRESENT OR
STOREDMOTORISED THROTTLE POSITION INCONSISTENT1.DEF: Inconsistency between throttle valve position and control.
2.DEF: Inconsistent signal.
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is considered present under the following conditions:
–For 1.DEF engine running at idle speed.
Special note:
For 1.DEF, the OBD warning light illuminates,
For 2.DEF, the OBD warning light and level 2 fault warning light illuminate.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Check the connection and condition of the motorised throttle valve connector, component code 1076 and the
injection computer connector, component code 120.
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3AJB between components 1076 and 120,
–3AJC between components 1076 and 120,
–3MP between components 1076 and 120,
–3MQ between components 1076 and 120,
–3MO between components 1076 and 120.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, contact the Techline.

TEST 19 Fuel conformity check
WARNING:
During this operation, it is essential to:
refrain from smoking or bringing incandescent objects close to the work area,
protect yourself against fuel splashes due to residual pressure in the pipes, wear safety goggles with side
guards and waterproof gloves (Nitrile type).
IMPORTANT:
To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Remove 1 L of fuel at the fuel filter outlet (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423 (Thalia
2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 19C, Tank, Fuel tank: Draining) using
a pneumatic transfer pump (part no. 634-200) and place it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and allow it to settle for approximately 2 minutes.
Check if the fuel is cloudy or if it separates into two parts.
If the fuel is cloudy or if it separates into two parts, there is water in the fuel, the fuel is not correct.
Drain the fuel circuit, including the tank (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423 (Thalia 2/
Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 19C, Tank, Fuel tank: Draining).
Visually compare the fuel removed with the correct petrol.
Are the samples identical?
If the samples are identical, this means that the fuel is correct.
If not, drain the fuel circuit, including the tank (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423
(Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 19C, Tank, Fuel tank:
Draining).
