Air flow meter

1. Loosen the fastening screws and remove the throttle casing with built-in DVL and seal.

NOTE: If the self-learning procedure is not correct, take the key to STOP and repeat the procedure. If the incorrect outcome persists, check the connection to the diagnostic socket and tool operation.

IMPORTANT: After refitting, repeat the throttle casing with built-in DVL self-learning procedure described below.

IMPORTANT: During this procedure (from when the instrument panel is powered to the end of the self-learning procedure), do not press either the accelerator pedal, the brake pedal or the clutch pedal.

• Make sure the ignition key is at STOP.
• Connect tool no. 1.806.365.000 to the diagnostic socket and turn the knob to 3.
• Connect Examiner.
• Turn the ignition key to MAR.
• Wait for 60 seconds for the ECU to check the throttle internal spring and the maximum/minimum angular positions.
• Turn the ignition key to STOP.
• Wait for 15 seconds for the ECU to record the learnt values in the EPROM.
• With Examiner, check whether the idling self-learning procedure was ended correctly (SELF-LEARNING OUTCOME - OK; SELF-LEARNING STORAGE - Done).
