1999 ELANTRA & TIBURON IDLE POSITION SWITCH ON A/T EQUIPPED VEHICLES
DESCRIPTION:
Effective June 1, 1999 production, the idle position switch (located on the throttle body, just below the throttle cam) is no longer used and is no longer
connected to the control harness.
NOTE:
The idle position switch connector from the control harness has been eliminated.
On vehicles produced prior to June 1, 1999, this switch informs the Transaxle Control Module (TCM) when the throttle is in the idle position. Beginning
with June 1, 1999 production, the idle position information is gathered by the TPS and delivered to the TCM by the Engine Control Module (ECM).
