TEST 8 Accelerator pedal potentiometer check
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Check the variation in PR055 Engine speed when depressing the accelerator pedal (with the engine running).
Stop the engine and switch on the ignition. Without action on the pedal, check that the voltage correction of circuit 1:
–PR147 Pedal potentiometer voltage gang 1 is less than 817 mV and
–PR148 Pedal potentiometer voltage gang 2 is less than 440 mV.
Next, in the "full load" position, check the circuit 1 voltage PR147, which must be greater than 4185 mV, and
PR148, which must be greater than 2013 mV.
Also check the pedal position in the following cases:
– "position zero" (PR030 Accelerator pedal position = 0)
– "Full load" (PR030 = 1).
Stop the engine and then switch on the ignition.
With the vehicle under + after ignition feed, measure the voltage between the following connections:
–3LR and 3LT of component 921,
–3LU and 3LV of component 921.
If the value is not between 4.75 VX5.25 V, check the insulation, the continuity and the absence of
interference resistance of the following connections:
–3LR between components 120 and 921,
–3LT between components 120 and 921,
–3LU between components 120 and 921,
–3LV between components 120 and 921.
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.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3LS between components 120
and 921,
–3LW between components 120 and 921.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

TEST 10 TDC sensor check
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Check the sensor fitting (connectors, mountings, etc.) (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,
Crankshaft position sensor: Removal - Refitting).
Switch on the ignition, check the change of the engine rotation speed using parameter PR055 Engine speed. The
value must be between 0 rpm and more than 120 rpm when the starter is operating.
With the engine running, accelerate to obtain different engine rotation speeds and check that the engine speed
correctly changes in relation to the accelerations.
If PR055 varies, the sensor is sound.
Check the cleanliness and condition of the TDC sensor, component code 149 and of the injection computer
connector, component code 120.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.

TEST 14 Ignition coil check
NOTESSpecial note:
To apply this procedure, use the special tool Elé. 1808: "ignition coil tester"
available in the Parts Department catalogue.
part number: 77 11 381 808.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
K4M engine
Visually inspect the condition of the connectors of pencil ignition coil no.1, component code 1077, pencil ignition
coil no.2, component code 1078, pencil ignition coil no.3, component code 1079, and pencil ignition coil no.4,
component code 1080 (see MR 388 (Logan et Sandero). MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR
430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 17A, Ignition, Coils: Removal - Refitting).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
Insert tool Elé. 1808 (1) in the coil.
Place the tool/coil assembly in the spark plug well.
Start the engine and let it idle.
Apply light pressure to the assembly to hold the coil in contact with the tool.
Observe the glow from the electric arc on the spark plug well wall.
If an electric arc is not produced, replace the coil concerned (see MR 388 (Logan and Sandero). MR 451 (Duster),
