CONTROL SYSTEM OUTLINE [WITH WU-TWC]

id0140001001d2
• The construction and operation of the control system is essentially carried over from that of the without WU-TWC models.

  - The EGR control has been adopted. (ZJ engine models)
  - A MAP sensor has been adopted.
  - A steering angle sensor has been adopted.
  - Electronic spark advance (ESA) control has been changed.
  - Idle air control (IAC) has been changed.
