CC.1: Short-circuit on +12 volts.
1.DEF: Above maximum threshold.
2.DEF: Below minimum threshold.
NOTESPriority when dealing with a number of faults:
- Deal first with fault DF113 Sensor supply voltage.
See Technical Note Wiring Diagrams of the vehicle concerned.
Check the connection and condition of the EGR valve connector, component code 169.
Check the connection and condition of connector B (brown 48-track) of the computer, 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, otherwise replace the wiring.
Check for +5 V on connection 3GC of component 169.
Check for earth on connection 3JM of component 169.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the insulation and continuity of the following connections:
–3GC between components 169 and 120,
–3EL between components 169 and 120,
–3JM between components 169 and 120.
If the connection or connections are faulty and if there is a repair method (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 169:
– with the engine stopped, the EGR 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 3GB. The resistance must be between
7.54 Ω < R < 8.5 Ω (at 20°C),
– measure the resistance between connections 3GC and
3JM. The resistance must be between
2.4 KΩ < R < 5.6 KΩ (at 20°C),
– measure the resistance between connections 3JM and 3EL, the resistance should be between
800 Ω < R < 3.6 KΩ (at 20°C),
if the value is not correct, replace the EGR valve, component code 1460 (see MR 364 (Mégane II), MR 370
(Scénic II), Mechanical, 14A, Emission control, Exhaust gas recirculation solenoid valve: Removal -
Refitting). If the EGR valve was replaced, use command RZ002 EGR adaptives to reinitialise the EGR valve
offsets.
If the fault is still present, contact the Techline.
