2004 NISSAN TERRANO turn signal

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.
