NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running.
Special notes:
This relay supplies the following actuators: the injectors, the throttle valve control, the
oxygen sensor heaters, the fuel vapour absorber bleed solenoid valve and connection
3FB of the injection computer.
CO/CC.1: No actuator supply: same effect as running out of fuel. The vehicle stalls and
will not start again.
CC.0: The actuators are supplied constantly: high electrical consumption when
stationary.
Intermittent CO: Intermittent relay cut-off: bucking when driving.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III, or
MODUS.
Check the condition of the engine management computer connector (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.
For NEW TWINGO or E33:
Check the condition of the injection locking relay connector (component code 238).
If the 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.
Use the universal bornier to check the insulation and continuity of the following connections:
●3AA between components 238 and 120,
●3FB between components 238 and 193, 194, 195, 196, 1076, 242, 887, 371.
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.

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.

NOTESSpecial notes:
Oil leaks and odours are possible.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the connector of the oil vapour rebreathing hose heater (component code 979) and of the
engine management computer (component code 120).
If the 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.
With the ignition on, check for + 12 V on connection 3FB of the oil vapour re-breathing pipe heater and the earthing
of connection 3YC on the injection computer connector.
Use the universal bornier to check the insulation and continuity of the following connections:
●3FB between components 979 and 238,
●3YC between components 979 and 120 (for NEW TWINGO or E33),
●3JP between components 979 and 120 (for CLIO III or MODUS).
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.
If the fault is still present, contact the Techline.

ET052UPSTREAM O2 SENSOR HEATING
STATUS
DEFINITIONACTIVE: This status indicates that the upstream oxygen sensor heater is active.
INACTIVE: This status indicates that the upstream oxygen sensor heater is inactive.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: engine stopped and ignition on.
"INACTIVE"The status is inactive when the engine is off.
In the event of a fault, apply interpretation of DF082 Upstream oxygen sensor
heating circuit.
Conformity check: engine running at idle speed, engine coolant temperature > 80˚C.
"ACTIVE"The status becomes active when the engine is started and its operation increases
according to the heating temperature.
In the event of a fault, apply the interpretation of DF082.
