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
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 20 Camshaft sensor check
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster.
Visually inspect the condition of the camshaft sensor.
Check the status of synchronisation of the camshaft sensor with the TDC sensor using ET775 Camshaft TDC*
synchronisation.
Is ET775 "NOT PERFORMED"?
Start the engine. Does the engine start?
With the starter operating, check the status of
synchronisation of the camshaft sensor with the TDC
sensor using ET775.At idle speed and after a few accelerations between
1000 and 2000 rpm, check the status of
synchronisation of the camshaft sensor with the TDC
sensor using ET775.

Check the condition and connection of the camshaft sensor connectors, component code 1265.
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 internal resistance of the camshaft sensor. It must be greater than 100 k.
Check for +12 V on the camshaft sensor, component code 1265 on the following connection:
•3FB of component 1265.
Check the continuity, insulation and the absence of interference resistance of the following connection:
•3FB between components 1265 and 1047.
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.
Check the continuity, insulation and absence of interference resistance on the following connections:
•3SX between components 1265 and 120,
•3SV between components 1265 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.
