PARAMETER
DEFINITIONThis parameter indicates the atmospheric pressure in bar. The sensor is integrated in
the computer.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III
or MODUS.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
The atmospheric pressure value is:
PR035 ≈ 1 bar +/- 0.20 bar
In the event of a fault, consult the interpretation of DF004 Turbocharging pressure sensor circuit.
Check the cleanliness and condition of the atmospheric pressure sensor and its connections (component
code 147) and the engine management computer (component code 120).
If the connector or 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 cleanliness of the air filter.
–Replace the filter if necessary.
–Check that the air inlet circuit is not blocked.
The turbocharging system must be perfectly sealed, from the exhaust manifold to the turbocharger, from the
turbocharger to the heat exchanger and from the heat exchanger to the throttle valve.
Check that there are no air leaks:
–around the turbocharger pressure sensor,
–around the air temperature sensor.
Check absence of leaks in the wastegate capsule pressure circuit connected to the turbocharger system.
Check that the air-air heat exchanger is not clogged (presence of oil).
If there is oil in the heat exchanger, the turbocharger is certainly damaged.
Using a pressure/vacuum pump, check that the turbocharger protection and turbocharging valve capsule
diaphragms do not leak.
Check the condition the motorised throttle valve in terms of clogging.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
