23 23 PA - ENGINE Front or Up Stream Oxygen Sensor Rear or Down Stream Oxygen Sensor Zirconia type oxygen sensor is used. The Zirconia oxygen sensor generates a small voltage depending on the exhaust gas condition. The normal voltage range is 0.2 ~ 0.8 volts. 0.2 volts indicates a lean mixture and a voltage of 0.8v indicates a richer mixture. Oxygen Sensor
24 24 PA - ENGINE Engine knock control is used to constrain the knocking. Knock sensor detects knocking generated in engine and retard ignition timing. The knock sensor is installed at between No2. and No.3 cylinder. Like other piezo type sensors, this is made by piezo material. Tightening torque is 20±5Nm. Knock Sensor Maximum Retard Limit : 12˚ When knocking is detected : Initially retard 3˚ and increase step by step with 0.75˚
25 25 PA - ENGINE The main role of wheel speed sensor is detecting the rough load condition which allows misfire monitoring inhibition (EOBD:Euro3/Euro4). When the vehicle is running on rough load condition, the CKP angular speed is affected from this road condition. It can signal to ECM as a misfiring. In this case wheel speed sensor detects this kind of rough load condition and order ECM not to consider this situation as a misfiring. Wheel Speed Sensor M/TInput VariableECU PIN NO.

Instead, ECM receives a corresponding vehicle speed from others. (refer to the table below)
27 27 PA - ENGINE Maintaining screw Coil assembly Magnet Drive unit Axis Housing Ball bearing Valve Stopper O-Ring Cushion ring ISA (Idle Speed Actuator) 1. The ISA controls the proper intake air mass in every engine operating conditions. 2. The ECU controls the ISA (double coil of open/close) with frequency of 250Hz. 3. The ISA duty is determined by basic map and compensation of ATS, WTS, altitude and A/CON compressed load etc.
