PR669PARTICLE FILTER DIFF* PRESS* SENS* VOLTAGE
PARAMETER
DEFINITIONThis parameter indicates the voltage of the particle filter differential pressure sensor in
volts.
NOTESThis parameter exists only on F9Q816 engines
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C, without electrical consumers
PR669 ατ 5 V
In the event of a fault, refer to the interpretation of fault DF315 Particle filter diff* pressure sensor.

– Check the consistency between the IMA codes read on the CLIP diagnostic tool and the codes engraved on
the injector bodies,
– Check that the particle filter differential pressure sensor is correctly positioned and connected (see MR 364
(Megane II) or 370 (Scenic II), Mechanical, 19B Exhaust, Particle filter pressure sensor: Removal -
Refitting),
– Check the exhaust pipe see (Test1 Exhaust pipe check),
– Check the air inlet circuit see (Test 4 Turbocharged air inlet circuit check),
– Check the air flowmeter, (see Test 5 Air flowmeter),
– Check the turbocharger, (see Test 6 Turbocharger control solenoid valve test and Test 7 Turbocharger),
– Check the injectors, (see Test 10 Poor injector operation),
– Check the cylinder compressions.
If the fault has not been located and the customer complaint is still present, contact the Techline.
