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.
