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.

With the engine warm in the idle speed regulation phase, look at parameter PR139.
– If the parameter goes to MAXIMUM stop, there is not enough fuel or too much air in the mixture.
– If the parameter goes to MINIMUM stop, there is too much fuel or not enough air in the mixture.
Check the cleanliness and correct operation of:
– petrol filter,
– petrol pump,
– fuel circuit,
