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, otherwise replace the wiring.
Measure the resistance between connections 3VP and 3VQ of component 1460 or 169.
If the resistance of the EGR valve is less than 1 Ω or greater than 400 Ω, replace the EGR valve.
After replacement, run command SC036 Reinitialise programming and select EGR valve to reinitialise the EGR
valve offsets.
Check the insulation between the following connections:
•3VP between components 120 and 1460 or 169,
•3VQ between components 120 and 1460 or 169.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical

Check the continuity and absence of interference resistance on the following connection:
•3WT between the components 120 and 414.
Check the + 12 V after relay supply to the water detection sensor on the following connection:
•3FB of component 414.
Check that the earth is in order on connection NT or M of component 414.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical

Start the engine and wait at least 1 minute to confirm the repair.
If the fault is still present, check the conformity of the fuel used:
– Check that the fuel tank has been filled correctly.
–Run Test 12 Fuel conformity check.
– If the diesel fuel is not correct:
– Replace the diesel fuel.
– Change the diesel filter.
– Bleed the low pressure diesel circuit.
