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
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
