CATALYTIC CONVERTER 1 TEMPERATURE SENSOR VOLTAGE
PARAMETER
DEFINITIONThis parameter indicates the catalytic converter 1 temperature sensor voltage in volts.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C
0.7 V ≤PR812 ≤5V
In the event of a fault, consult the interpretation of fault DF1007 Catalytic converter 1 downstream temperature
sensor circuit or DF1009 Catalytic converter 1 downstream temperature regulation.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 21 Particle filter warning light on
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Check that the particle filter operates by running Test 9 Particle filter history.
Check that there is fuel in the tank.
Put fuel in if necessary.
Carry out a visual inspection of the air filter/filter box.
● Check the condition of the air filter (fouling, clogging, etc.).
If necessary, replace the air filter (see MR 392, 385, 364, 370 and 417 Mechanics, 12A, Fuel mixture, Air filter:
Remove - Refitting).
●Check that the air filter box inlet and outlet are not obstructed.
Repair if necessary.
Check the catalytic converter no. 1 downstream temperature sensor:
●Check there is no corrosion inside the connector and repair if necessary.
●With the + after ignition feed switched on, check for the + 5 V feed on the following connection:
– Connection code 3AGY between component 1765 and the vehicle earth.
●Check the continuity, insulation and absence of interference resistance on the following connections:
– Connection code 3AGX between components 1765 and 120.
– Connection code 3AGY between components 1765 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the particle filter upstream temperature sensor.
●Check there is no corrosion inside the connector and repair if necessary.
●Check for the earth on the following connection:
– Connection code 3XT between components 1287 and 120.
●Check the continuity, insulation and absence of interference resistance on the following connections:
– Connection code 3TD between components 1287 and 120.
– Connection code 3XT between components 1287 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

With + after ignition feed on, check for + 12 V feed between connection codes 3AHB and M at the electric pump
connector of the particle filter injector, component code 1767.
If there is no + 12 V feed to the sensor, check the continuity, insulation and absence of interference
resistance on the following connections:
●connection code 3AHB between components 1767 and 1768,
●Connection code M between component 1767 and the vehicle earth.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
(Refer to the interpretation of faults DF1004 Electric fuel pump relay control and DF1001 Particle filter
upstream temperature regulation).
●Reconnect or replace the pipe.
Repeat the pressure test.
●Replace the fuel filter (see MR 392, 385, 364, 370 and 417 Mechanics, 13A, Fuel supply, Fuel filter:
Removal - Refitting).
Repeat the pressure test.
●Replace the particle filter injector electric pump.
Repeat the pressure test.
●Check that the particle filter injector is fitted correctly.
Check that the particle filter injector is correctly held in place. Repair or replace the particle filter injector mounting.
●"Only on Kangoo 2:
Check the integrity and correct fitting of the evaporator plate located under the particle filter injector, at the level of
the bracket.
If the blade of the evaporator plate has become detached, it may be located downstream from the line between its
original position and the oxidation catalytic converter inlet.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
