Check the connection and condition of the EGR valve connector, component code 1460.
Check the connection and condition of connector B (brown 48-track) of the injection computer, component
code 120.
If the connector(s) is 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.
Check the insulation and continuity of the following connections:
–122B between components 1460 and 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 the wiring.
Check for + 12 V on connection 3GC of component 1460.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the resistance of the EGR valve, component code 1460:
–with the engine stopped, the exhaust gas recirculation valve will be closed (unless there is a fault),
–wait for the ambient temperature around the valve to stabilise (approximately 20
°C),
–measure the resistance between connections 3FB2 and 122B. The resistance must be between 7.5 ΩΩ Ω Ω
< R
< 8.5 ΩΩ Ω Ω
(at 20
°C),
–measure the resistance between connections 3GC and 3JM. The resistance must be between 2.4 kΩΩ Ω Ω
