PRESENT OR STORED

CC.1 : Short circuit to + 12 V

CO.0 : Open circuit or short circuit to earth 1. DEF: Micro-breaks

NOTES

Conditions for application to a stored fault:

The fault is declared present after the ignition has been switched on for at least 10 seconds.

If the fault is present:

– the OBD warning light is lit,

– small amount of smoke may be present,

– the atmospheric pressure value changes to safe mode, PR035 Atmospheric pressure = 900 mbar.

Special notes:

The atmospheric pressure sensor is integrated into the injection computer and cannot be separated.

Disconnect the injection computer, component code 120, and check the condition of the contacts and the condition of its connector (see MR 392, 385, 364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel injection computer:

Removal - Refitting).

If the connector is 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.

If the fault is still present, contact the Techline.

AFTER REPAIR

Deal with any faults displayed by the diagnostic tool.

Clear the computer fault memory.

NOTES

Priority when dealing with a number of faults:

First apply the procedure for dealing with the fault DF012 Sensor supply voltage no. 2.

Conditions for application to a stored fault:

The fault is declared present after the ignition has been switched on.

If the fault is present:

– the EGR function is inhibited,

– the turbocharging pressure value is in safe mode, PR041 Turbocharging pressure sensor = 1000 mbar,

– turbocharging is cut off.

Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring diagrams Technical Note.

Check the connection and condition of the turbocharging pressure sensor connector, component code 1071 and the injection computer, component code 120 (see MR 392, 385, 364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).

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.

With the ignition on, check for the presence of + 5 V on connection 3LQ and check for an earth on connection 3LN on the turbocharging pressure sensor, component code 1071.

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.

Check the insulation, continuity and the absence of interference resistance on the following connections:

– 3LQ between components 1071 and 120, – 3LP between components 1071 and 120, – 3LN between components 1071 and 120.

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.

If the fault is still present, replace the turbocharging pressure sensor.

AFTER REPAIR

Deal with any faults displayed by the diagnostic tool.

Clear the computer fault memory.

Carry out a road test followed by another check with the diagnostic tool.

Priority when dealing with a number of faults:

First deal with fault DF003 Atmospheric pressure sensor circuit.

Conditions for application to a stored fault:

The fault is declared present after the ignition has been switched on for 1 second, with a warm engine and when the vehicle is stationary.

If the fault is present:

– the EGR function is inhibited,

– the turbocharging pressure value is in safe mode, PR041 Turbocharging pressure sensor = 1000 mbar,

– turbocharging is cut off.

– the maximum torque supplied by the engine is restricted.

Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring diagrams Technical Note.

Check the connection and condition of the turbocharging pressure sensor connector, component code 1071 and the injection computer, component code 120 (see MR 392, 385, 364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).

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.

With the ignition on, check for the presence of + 5 V on connection 3LQ and check for an earth on connection 3LN on the turbocharging pressure sensor, component code 1071.

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.
