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

TEST 4 Fuel vapour absorber solenoid valve check
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Check the cleanliness, mounting, possible leaks and the hoses of the fuel vapour absorber solenoid valve,

Check or MR 451 (Duster) or MR 423 (Thalia 2/Symbol 2), Mechanical, 14A, Emission control, Fuel vapour
absorber: Removal - Refitting).
Listen for the operation of the solenoid valve while running command AC017 Canister bleed solenoid valve.
With the engine idling, disconnect the pipe at the solenoid valve inlet and check that there is no suction on your
finger. (These steps allow the sealing of the solenoid valve to be checked for air tightness.)
Check the cleanliness and condition of the canister bleed solenoid valve connector, component code 371 and
of the injection computer connector, component code 120.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3FB between components 371 and 1047 (for Logan, Sandero, Duster) or 238 (for Thalia 2/Symbol 2, Kangoo
VLL) or 983 (for Clio II F 6),
