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),

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.

–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,
