NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present if:
– ignition is on (CC.0),
– following a road test, engine warm (CO.1).
Special notes:
If the fault is present:
– the EGR function is inhibited,
– particle filter regeneration is inhibited,
– the vehicle performance is reduced,
–the level 1 warning light is lit.
IMPORTANT
The turbine upstream temperature sensor only measures temperatures above
100°C.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and Kangoo II Wiring
diagrams Technical Note.
Run command AC029 High pressure circuit sealing check and check PR667 Turbine upstream temperature.
If the turbine upstream temperature is above 120°C, then the sensor is correct, otherwise continue the fault
finding procedure.

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(s); otherwise, replace the wiring.
Measure the resistance of the turbine upstream temperature sensor, component code 1589 between
connections 3B and 3JQ.
If the resistance is not between 313 KΩ and 436 KΩ at 100°C, replace the turbine upstream temperature
sensor.
With the ignition on, check for + 5 V on connection 3B and earth on connection 3JQ of the turbine upstream
temperature sensor, component code 1589.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
