Component Description
CONTROL SLEEVE POSITION SENSOR (CSPS)
The control sleeve position sensor is installed on the electric gov-
ernor. It senses the position of control sleeve (rotor angle) while the
control sleeve is being driven by the electric governor, and feeds it
back to the ECM.

DTC Confirmation Procedure
WITH CONSULT-II
1) Turn ignition switch to “ON” position and select “DATA MONI-
TOR” mode with CONSULT-II.
2) Start engine and run it for at least 2 seconds at idle speed.
WITHOUT CONSULT-II
1) Start engine and run it for at least 2 seconds at idle speed.
2) Turn ignition switch to “LOCK” position, wait at least 5 seconds
and then to “ON” position.
3) Perform “Diagnostic Test Mode II (Self-diagnostic results)”.
