Check the resistance value of the upstream oxygen sensor, component code 887 on the computer connector side,
component code 120. With the engine stopped for 10 minutes, the resistance value must be between 7< X <
11 or 3 < X < 5 (F4R engine of Duster) (between 0°C and 40ºC).
If the resistance is not correct, replace the upstream oxygen sensor, component code 887 (see MR 388 (Logan
and Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL),
Mechanical, 17B, Petrol injection, Oxygen sensors: Removal - Refitting).
Check that the TDC* sensor programming is correct (see section: Replacement of components).
Run test SC007 Run OBD test: O2 sensor
and start the engine (Only depress the brake pedal to authorise the
starting of the engine).
At the end, check the test results:
STATUS1: Run the test again with the engine coolant temperature X > 90°C.
STATUS2 or STATUS3: Sensor OK.
STATUS4: Replace the upstream oxygen sensor (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423
(Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 17B, Petrol injection, Oxygen
sensors: Removal - Refitting).
If the fault is still present, contact the techline.

TEST 18 Downstream O2 sensor check
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Visually check the position and mounting of the downstream oxygen sensor (see MR 388 (Logan and Sandero),
MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 17B,
Petrol injection, Oxygen sensors: Removal - Refitting).
With the engine warm, PR064 Coolant temperature >70°C, depress the accelerator pedal for 3 minutes, perform
several accelerations and check that PR099 Downstream oxygen sensor voltage varies correctly between: 0
mV < PR099 < 1000 mV.
Check the connection and condition of the downstream oxygen sensor connector, component code 242 and of the
injection computer connector, component code 120.
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation, continuity and absence of interference resistance on the following connection:
–3GL between components 242 and 120,
–3GJ between components 242 and 120.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the resistance value of the downstream oxygen sensor, component code 242 on the computer connector
side, component code 120. With the engine stopped for 10 minutes, the resistance value must be between 7<
X < 11 (between 0°C and 40°C).
If the resistance is not correct, replace the downstream oxygen sensor, component code 242 (see MR 388 (Logan
