PRESENT
OR
STOREDPINKING SENSOR CIRCUIT
1.DEF: Abnormal voltage
2.DEF: EOBD
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running with an engine coolant
temperature above 75˚C and the engine speed above 1500 rpm.
Special notes:
1.DEF: The wiring harness connecting the injection computer to the sensor is shielded.
Because of this, a short circuit to + 12 V is unlikely.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the pinking sensor connector (component code 146) 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.
Check the tightening of the pinking sensor (tightening must be: X = 20 Nm).
Repair if necessary.
Measure the resistance of the pinking sensor between connections 3S and 3DQ:
The resistance should be greater than 20 MΩ.
If the pinking sensor resistance is not correct, replace the sensor.

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.

STOREDCONTROLLED COOLANT THERMOSTAT CIRCUITCO: Open circuit
CC.0: Short circuit to earth

1.DEF: EOBD
NOTESPriorities when dealing with a number of faults:
Deal first with fault DF084 Actuator relay control circuit or DF046 Battery voltage
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present when the engine is running.
Special note:
Controlled coolant thermostat:
–For CO and CC.1:
Thermostat not controlled; temperature regulation performed at 110˚C.
–For CC 0:
Thermostat continuously controlled; temperature regulation performed at 90˚C.
Use Wiring Diagram Technical Note for CLIO III or MODUS.
Check the condition of the controlled coolant thermostat connector (see Technical Note Wiring Diagram, CLIO III
or MODUS, component code 1458).
Check the condition of the engine management computer connector (see Technical Note Wiring Diagram,
CLIO III or MODUS, 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.
If the fault is still present, check (with the ignition on) for + 12 V on connection 3FB of the controlled coolant
thermostat.
If the connection is faulty and if 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 connection:
●3VL between components 1458 and 120.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.

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.

CONTINUED 1
Deal with DF001 Coolant temperature sensor circuit first.
Check the consistency of PR064 Coolant temperature.
If this status is inconsistent:
Disconnect the battery.
Check the condition of the engine management computer connector (component code 120).
For NEW TWINGO or E33:
Check the condition of the air conditioning control unit connector (component code 419).
If the connector(s) is(are) faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, 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:
●133B between components 120 and 419,
●133C between components 120 and 419.
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, carry out fault finding on the UCH system (see 87B, Passenger compartment
connection unit).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
Repeat the conformity check from the start.
