PR037REFRIGERANT PRESSURE
PA R A M E T E R
DEFINITIONThis parameter indicates the refrigerant pressure in bar.
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature >
80°C.
The refrigerant pressure must be between 2 bar < PR037 < 27 bar.
Check the cleanliness and condition of the refrigerant pressure sensor and its connections, component code
1202 and the injection computer connections, 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.
Disconnect the battery and the injection computer.
Using the universal bornier in place of the computer, check for insulation and continuity on the following
connections:
–38Y between components 120 and 1202,
–38X between components 120 and 1202,
–38U between components 120 and 1202.
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, replace the refrigerant pressure sensor, component code 1202 (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),

(See MR 388 (Logan and Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), Mechanical, 62A, Air
conditioning: Precautions for repair) and (see MR 388 (Logan and Sandero), MR 451 (Duster) or MR 423
(Thalia 2/Symbol 2), Mechanical, Air conditioning: Parts and consumables for the repair).
If the fault is present, check the air conditioning circuit (see MR 388 (Logan and Sandero), MR 451 (Duster) or
MR 423 (Thalia 2/Symbol 2), Mechanical, 62A, Air conditioning: Check).
