Fault finding – Interpretation of statuses13B
ET120PRE-POSTHEATING SIGNAL
STATUS DEFINITIONPRESENT: This status indicates that the pre-postheating signal is still active.
ABSENT: This status indicates that the pre-postheating signal is not active.
NOTESTest the battery and run fault finding on the charging circuit (see Technical Note
6014A, Checking the charging circuit).
Special notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80 °C
PRESENTStatus ET120 is PRESENT when preheating is activated.
ABSENTThe status ET120 is ABSENT as long as pre-postheating is not activated. See
interpretation of faults DF025 Preheating unit diagnostic line and DF017
Preheating unit control circuit.

PR009TURBOCHARGING PRESSURE SETPOINTS
PARAMETER
DEFINITIONThis parameter indicates the theoretical turbocharging pressure setpoint value in bar.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
The theoretical turbocharging pressure value is a setpoint, i.e. PR009 ≈ 1 bar

Sensor electrical conformity
Check the continuity and absence of interference resistance on the following connections:
– connection code 3LQ,
– connection code 3LP,
– connection code 3LN.
between components 120 and 1071.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
Vehicle with ignition on, and the engine stopped for over 1 minute:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar,
check the value of PR035 "Atmospheric pressure" by comparing it with the reading on a vehicle in the workshop
which is correct.
If the value of PR035 Atmospheric pressure is not correct (difference greater than 0.1 bar between the 2
vehicles), contact the Techline.
Otherwise (when the value PR035 Atmospheric pressure is correct), change the turbocharging pressure sensor.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.1 bar.
Start the engine, with the engine idling:
Compare the values of PR041 and PR035 Atmospheric pressure.
If the difference between PR041 and PR035 Atmospheric pressure is greater than 0.2 bar.
Check the air inlet circuit:
The low and high pressure air circuit is sealed and not obstructed: the pipes and mounting clamps are present
and tightened, turbocharging pressure sensor, intercooler, etc. are fitted.
Check that the damper valve is not jammed closed.
Repair if necessary.
