NOTESConditions for application to a stored fault:
The fault is declared present during a warm engine road test at an engine speed of
more than 3500 rpm.
Special notes:
–The Level 1 warning light is illuminated.
– The wiring harness connecting the injection computer to the pinking sensor is
shielded, therefore a short circuit at + 12V is unlikely.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Check the cleanliness and condition of the pinking sensor, component code 146 and its connector.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the tightening of the pinking sensor (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, 17B, Petrol injection, Petrol
injection: List and location of components).
Check the cleanliness and condition of the injection computer connections, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector(s), otherwise, replace the wiring.
Check the internal resistance of the pinking sensor, component code 146. The resistance value of the sensor must
be: X > 10M. If the value is not correct, replace the pinking sensor, component code 146 (see MR 388 (Logan
and Sandero), Mechanical, 17B, Petrol injection, Petrol injection: List and location of components, MR 451
(Duster) or MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6), MR 374 (Kangoo VLL), Mechanical, 17B, Petrol
injection, Pinking sensor: Removal - Refitting).
Check the continuity and insulation of the following connections:
–3S between components 120 and 146,
–3DQ between components 120 and 146,
–TB1 of component 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact Techline.
