STOREDINLET AIR TEMPERATURE SENSOR CIRCUIT
CO.1 : Short circuit or open circuit to + 12 V
CC.0 : Short circuit to earth
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after one attempt to start the engine, or with the engine
running.
Special notes:
If the fault is present:
–the air temperature value enters defect mode, i.e. PR059 Inlet air temperature =
20˚C.
–the EGR function is inhibited,
–the level 2 warning light is lit.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
CO.1
NOTESNone
Check the air flowmeter connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity of the following connection:
Injection supply relay mounting Track 5 track 4 air flow sensor connector
Repair if necessary.
Check the continuity and insulation against + 12 V of the following connections:
Injection computer brown 48-track connector B,
track G2Track 1 air flowmeter connector
Injection computer brown 48-track connector B, track E2 Track 2 air flowmeter connector

Measure the air temperature sensor resistance between tracks 1 and 2 of the air flow sensor.
Replace the air flowmeter if the resistance displayed is not:
3714 ± 161 Ω at 10˚C
2448 ± 96 Ω at 20˚C
1671 ± 59 Ω at 30˚C
CC.0
NOTESNone
Check the air flowmeter connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and insulation against earth of the connection between:
Injection computer brown 48-track connector B, track G2 Track 1 air flowmeter connector
Injection computer brown 48-track connector B, track E2 Track 2 air flowmeter connector
Injection computer brown 48-track connector B, track B4 Track 3 air flowmeter connector
Injection supply relay mounting Track 5 track 4 air flow sensor connector
Repair if necessary.
Measure the air temperature sensor resistance between tracks 1 and 2 of the air flow sensor.
Replace the air flowmeter if the resistance is not approximately:
3714 ± 161 Ω at 10˚C
2448 ± 96 Ω at 20˚C
1671 ± 59 Ω at 30˚C

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine has been started.
Special notes:
If CC.1, CC, or 1.DEF is present, the level 2 warning light is lit.
If CO is present the level 1 warning light is lit.
If CO is still present, the OBD warning light will come on after three consecutive driving
cycles (starting + 5 seconds + switching off the ignition and waiting for 1 minute).
If the fault is present, the injection on cylinder 1 is disabled.
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This test enables the condition and the conformity of the engine wiring harness to be checked.
