(1) Function: To provide information on coolant temperature. To provide water temperature signal for the ECU, and to control ignition timing and fuel injection pulse width at start, idle speed, and (2) Structure and principle: Made by a thermistance with NTC. The resistance value will decrease with the increase of the coolant temperature (not a linear relation). The thermistance (3) Connection of wiring diagram (Fig. 1-6)
KS1-7 (1) Function: To provide engine knock information for the ECU for knock control. (2) Structure and principle: As a vibration acceleration sensor, installed on the cylinder block of the engine. The sense element of the sensor is a piezoelectric element. The vibration of the 25 |
