ELECTRONIC THROTTLE CONTROL SYSTEM
(ETS) INITIALIZATION
This TSB supersedes TSB # 02-36-005. This TSB information applies to the XG350, as well as the XG3OO and Santa Fe 3.5L.
DESCRIPTION:
The XG300, XG350, and Santa FE 3.5L incorporate an Electronic Throttle control System (ETS).
The main advantages of the ETS:
^
Precise control of the throttle plate in response to the driver's input.
^
System integration with idle speed control, cruise control and traction control.
The main components of the ETS and their functions are:
1.
Accelerator Pedal Position Sensor (APS): This sensor detects the driver's throttle input. This is a redundant sensor: two sensors in one housing.
2.
ETS Control Module: This module controls the electric motor which controls the throttle valve. (2001-2004 XG300/350 only)
3.
Throttle body with:
A.
Redundant TPS (two sensors in one housing): This sensor detects the position of the throttle valve.
B.
Electric Motor for controlling the throttle valve (3-phase, brush less, DC motor):
This motor directly controls the throttle valve opening angle.
C.
Limp Home Valve: This valve allows the engine to continue running in case of certain ETS malfunctions.
