Use the "universal bornier" to check the insulation and continuity of the following connection:
●3FB between components 887 and 1337.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If the + 12 V is still not present on the upstream oxygen sensor connector with the ignition on, there is a fault with
the Protection and Switching Unit.
Run fault finding on the UPC, component code 1337 (see 87G, Engine compartment connection unit).
Check the condition of the connector for the engine management computer (see Wiring Diagram Technical Note
for NEW TWINGO, E33, CLIO III, or MODUS, component code 120).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the "universal bornier" to check the insulation and continuity of the following connection:
●3GF between components 887 and 120.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check for an earth on connection 3GH of the upstream oxygen sensor during activation of command AC117
Upstream O2 sensor heating.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Measure the heating resistance of the upstream oxygen sensor:
If the resistance of the upstream oxygen sensor is not between:
●8 Ω < X < 10 Ω at 20 ˚C, replace the upstream oxygen sensor.
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair:
- If the fault is present, continue to deal with the fault.
- If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.

Conditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running or when using command AC118
Downstream O2 sensor heating.
Special notes:
CO/CC.1: No downstream sensor heating: the vehicle is polluting and the OBD
warning light is lit.
CC.0: Downstream sensor heating on continuously from switching on the ignition: risk of
sensor being irreparably damaged.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III, or
MODUS.
For NEW TWINGO or E33:
Check the condition of the downstream oxygen sensor connector (component code 242).
