Lambda Probe; Signal Control - APRILIA SR MAX 125 ie Service Station Manual

Injection
Make sure that the throttle valve with the control is
supporting the stop screw.
Guaranteeing that this position will be kept, send a confirmation for the TPS reset procedure.
Reset should be performed in the following cases:
- on first fitting.
- if the injection control unit is replaced.
NOTE
THE TPS RESET PROCEDURE MUST NOT BE CARRIED OUT WITH A USED THROTTLE BODY
BECAUSE POSSIBLE VALVE WEAR AND STOP WEAR FOR THE MINIMUM OPENING MAKE THE
AIR FLOW DIFFERENTLY FROM THAT OF PRE-CALIBRATION.
Given that the TPS resetting is also done when the
control unit is replaced, place the control unit - filter
box bellows at 45° during the refitting operation as
shown in the picture.
