TEST 7 Air inlet pressure sensor check
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Check the fitting and sealing of the inlet air pressure sensor, component code 147 (condition of the seals) and look
for possible leaks on the inlet air pipe. Ensure the conformity of the system (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, Air inlet: Description).
With the ignition on, compare the value of PR312 Manifold pressure for the vehicle concerned with that given by
another vehicle (absolute difference < 130 mbars).
Check the connection and condition of the connector of the inlet air pressure sensor, component code 147 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 supply voltage of the sensor on connections 3AJR and 3AJP.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3AJP between components 120 and 147,
–3AJR between components 120 and 147,
–3AJQ between components 120 and 147.
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.
With the ignition on, use a vacuum pump in order to create a variation in negative pressure. Then use the
diagnostic tool to check that PR312 500 mbar.
Replace the inlet air pressure sensor, component code 147 (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,

NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero.
Listen to the operation of the additional fuel pump and of the petrol pump relay of the additional circuit by running
command AC224 Additional petrol circuit pump relay.
Check the supply of the solenoid valve using a test light, by running command AC224.
If the supply is correct, replace the additional fuel pump (see MR 388 or MR 374 Mechanical, 19C, Tank,
Additional fuel tank: Removal – Refitting).

–3ACL between components 1639 and 283,
–NH (for Logan, Sandero, Duster) or M (for Thalia 2/Symbol 2) or MHA (for Clio II F 6) or MH (for Kangoo VLL)
between the earth and 283.
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.

TEST 19 Fuel conformity check
WARNING:
During this operation, it is essential to:
refrain from smoking or bringing incandescent objects close to the work area,
protect yourself against fuel splashes due to residual pressure in the pipes, wear safety goggles with side
guards and waterproof gloves (Nitrile type).
IMPORTANT:
To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Remove 1 L of fuel at the fuel filter outlet (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, 19C, Tank, Fuel tank: Draining) using
a pneumatic transfer pump (part no. 634-200) and place it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and allow it to settle for approximately 2 minutes.
Check if the fuel is cloudy or if it separates into two parts.
If the fuel is cloudy or if it separates into two parts, there is water in the fuel, the fuel is not correct.
Drain the fuel circuit, including the tank (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, 19C, Tank, Fuel tank: Draining).
Visually compare the fuel removed with the correct petrol.
Are the samples identical?
If the samples are identical, this means that the fuel is correct.
If not, drain the fuel circuit, including the tank (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, 19C, Tank, Fuel tank:
Draining).
