Vehicle: Trafic II Phase 2 and 3 Computer name: BOSCH EDC17 C11, EDC17 C42

Engine: M9R 630, M9R 692
Program No.: 9A, 1704
DIESEL INJECTION Vdiag No.: 04, 21


DF002
PRESENT
OR STORED
AIR TEMPERATURE SENSOR CIRCUIT
1.DEF: Signal outside lower limit.
2.DEF: Signal outside upper limit.

Note: The inlet air temperature sensor is integrated into the air flowmeter.

Conditions for application to a stored fault:
The fault is declared present after the ignition has been switched on.

If the fault is present:
¡V The turbocharging pressure is limited.
¡V The EGR valve is closed.
¡V The damper valve is open

Special notes:
After this fault appears:
¡V Reduction in engine performance,
¡V The OBD and Level 1 warning lights illuminate

See Wiring Diagram Technical Note for Trafic II ph 2 and ph 3.

Check the connection and condition of the air flowmeter connector, component code 799.
Check the connection and condition of the injection computer connector, component code 120.
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance of the following connections:
¡V 3ABQ between components 799 and 120.
¡V 37X between components 799 and 1834.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Measure the resistance of the air temperature sensor, component code 799 between connections 3ABQ and
37X of the air flowmeter, component code 799
If the resistance measured is not between 50 ohms and 30K ohms replace the air flowmeter, component code 799
(see MR 408, Mechanical, 12A, Fuel mixture, Air flowmeter: Removal - Refitting).

hope this helps you on this occasion mark
