STOREDREFRIGERANT PRESSURE SENSOR CIRCUIT
1.DEF: Abnormal voltage
NOTESPriorities when dealing with a number of faults:
Deal first with fault DF011 Sensor feed voltage no. 1 if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the ignition is switched on.
Special notes:
If the fault is present or stored, parameter PR037 Refrigerant pressure displays a safe
value of 0 bar, and the air conditioning no longer operates.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the refrigerant pressure sensor connector (component code 1202) and the engine
management computer connector (component code 120).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the universal bornier to check the insulation and continuity of the following connections:
●38U between components 120 and 1202,
●38X between components 120 and 1202,
●38Y 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 sensor.
SIM32_V44_DF232/SIM32_V4C_DF232/SIM32_V50_DF232/SIM32_V54_DF232
AFTER REPAIRFollow the instructions to confirm repair:
–If the fault is present, continue to deal with the fault.
–If the fault is stored, ignore it.
Deal with any other faults.
Clear the stored faults.

1.DEF: EOBD
NOTESConditions for applying the fault finding procedure to stored faults
The fault is considered present when the engine is running.
Special note:
CO or CC.1: Not possible to control the air conditioning and the customer is complaining
that driving comfort is reduced.
CO: No impact on the system.
CC.0: The compressor is still active, risk of irreversible damage to the compressor
(loss of capacity). The customer is complaining that the air conditioning is operating
continuously.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the low-speed fan assembly relay connector (component code 700) and the engine
management computer connector (component code 120).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run command AC154 Low speed fan assembly.
If the command does not work, with the ignition on, check for + 12 V on connection 3FB of the low-speed fan
assembly relay and the earthing of connection 3JN on the injection computer connector.
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.
Use the universal bornier to check the insulation and continuity of the following connections:
●3FB between components 700 and 238,
●3JN between components 700 and 120.
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, contact the Techline.

NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present with the engine running.
Special note:
CO or CC.1: High speed fan assembly not activated, risk of engine overheating (the
coolant warning light should warn of overheating), risk of loss of air conditioning.
CC.0: High-speed fan assembly permanently activated.
The customer complains of slight overconsumption and noise in CC.0.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the high-speed fan assembly relay connector (component code 234) and the engine
management computer connector (component code 120).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run command AC153 High speed fan assembly.
If the command does not work, with the ignition on, check for + 12 V on connection 3FB of the high-speed fan
assembly relay and the earthing of connection 3JP on the injection computer connector.
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.
Use the universal bornier to check the insulation and continuity of the following connections:
●3FB between components 234 and 238,
