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.
