With the ignition on, if the + 12 V is still not present on the downstream oxygen sensor connector, there is a fault
in the engine fuse and relay box.
Run fault finding on the engine fuse and relay box to check the continuity of the following connections:
●BP17 between components 120 and 597,
●BP17 between components 1033 and 597.
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, check the battery and run fault finding on the charging circuit (see Technical Note 6014A,
Checking the charging circuit).
For CLIO III or MODUS:
Check the condition of the Protection and Switching Unit (see Wiring Diagram Technical Note, CLIO III or
MODUS, component code 1337).
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 1337 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.
If the fault is still present, there is a fault in the Protection and Switching Unit (the actuator relay is in the Protection
and Switching Unit and cannot be dismantled).
Run fault finding on the UPC, component code 1337 (see 87G, Engine compartment connection unit).
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.

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.
