Reset should be performed in the following cases:
- on first fitting.
- if the injection control unit is replaced.
N.B.
THE TPS RESETTING 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 photograph.
