TEST 3 Throttle valve check
NOTESNone.
Check that parameter PR444 Idle speed regulation integral correction is between:
5 N.m < PR444 < 10 N.m (K4M, K7M engine) or -5 N.m < PR444 < 5 N.m (D4D, F4R and K4M engine of Duster).
The attempt is made with the engine idling and warm (75°C), without any electrical consumers switched on. The
value of PR444 must be read at least 20 minutes after the engine coolant temperature has reached 75°C.
If the value of PR444 is greater than 10 N.m (K4M, K7M engine) or 5 N.m (D4D, F4R and K4M engine of Duster),
reprogram the throttle valve using command RZ031 Throttle stop programming.
If the value of PR444 is less than -5 N.m, check the fitting of the throttle and check for possible air leaks (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, 12A, Fuel mixture, Throttle valve: Removal - Refitting).

TEST 15 Coolant temperature sensor check
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
With the engine idling: visually check that there are no leaks from the fitting of the coolant temperature sensor,
component code 244 (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, 19A, Cooling, Coolant temperature sensor: Removal
- Refitting).
Switch off the engine. Wait for 15 minutes, restart the engine and, for 10 minutes, check that the temperature
value given by the sensor increases, using parameter PR064 Coolant temperature.
If the value increases, the sensor is sound.
Check the condition of the coolant temperature sensor connector, component code 244 and the injection
computer connector, component code 120.
If the connectors are faulty and if 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 supply between connections 3JK and 3C of component 244.
Check the insulation, continuity and absence of interference resistance on the following connections:
–3JK between components 244 and 120,
–3C between components 244 and 120.
If the connections are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, replace the coolant temperature sensor, component code 244 (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),

TEST 17 Upstream 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 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).
With the engine warm, PR064 Coolant temperature >70°C, depress the accelerator pedal and check that PR098
Upstream oxygen sensor voltage varies correctly between: 20 mV < PR098 < 1395 mV. The variation must be
greater than 50 mV.
Check the connection and condition of the upstream oxygen sensor connector, component code 887 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:
–3GH between components 887 and 120,
–3GK between components 887 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.
