Run command SC007 Run OBD Test: O2 sensors.
The aim of this scenario is to detect a fault causing the EOBD* threshold for pollutant emissions to be exceeded.
There are two kinds of oxygen sensor damage:
–mechanical damage to the component (breakage, cut in wire) which leads to an electrical fault,
–chemical or thermal damage to the component leading to a slower response time of the sensor and to the
increase in the average reaction time.
Before carrying out this test, repair all the electrical faults and clear the fault memory.
Deal first with the DF436 Misfiring detection fault and program the flywheel target ET089 Flywheel target
programming.
Perform this test when the engine is warm, which reduces the time it takes for the catalytic converter to heat up.
Fault finding is entirely autonomous. When completed, the throttle control ceases and the engine returns to idling
speed regulation operation.
At the end of this test, four different results are possible:
–status 1: Fault finding not carried out/impossible to establish the necessary conditions.
–status 2: Component in an average condition.
–status 3: Component in good condition.
–status 4: Component in poor condition.
When fault finding is completed and the result read, stop the engine and start it again to establish normal operating
conditions.
If the result is status 1: check for any faults, and the engine flywheel target programming using ET089
Programming engine flywheel target.
If the result is status 2 or status 4, replace the sensor.
If the result is status 3, the sensor is in good condition.
If the fault is still present, contact the Techline.
AFTER REPAIRIf the throttle valve has been replaced, program the throttle stops, RZ005 Programming.
Follow 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.

NOTESNOTES
Priorities when dealing with a number of faults:
Deal with the faults DF084 Actuator relay control circuit and DF046 Battery voltage
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the ignition is switched on or with the engine running.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the connector of the downstream oxygen sensor computer (component code 242) and of
the engine management computer (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 connections:
●3GJ between components 242 and 120,
●3GL between components 242 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 it.
If the fault is still present, contact the Techline.

WARNING:
Never drive the vehicle without having confirmed that no faults involving the throttle valve are present.
NOTESPriorities when dealing with a number of faults:
Deal first with fault DF012 Sensor supply voltage no. 2 whether it is present or
stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the ignition is switched on.
Special notes:
The level 1 fault warning light is lit, the injection goes into defect mode 4, causing a
maximum speed limitation of 66 mph (110 km/h) and a loss of power when accelerating
(impression of having a "soft" pedal).
2.DEF: The throttle valve goes into defect mode 1 and 2, causing a limitation of vehicle
and engine speed. The ESP and the cruise control - speed limiter are deactivated.
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) and of the throttle
valve connector (component code 1076).
Check that the throttle valve rotates correctly (no resistance).
Check the condition.
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.
