The detection circuit of Daewoo ESPERO No.23 and 25 fault codes

Published:2011/5/17 4:37:00 Author:Borg | Keyword: detection circuit, fault codes

Fault code of 23 means the signal voltage of air temperature sensor is too high,(MAT) and the 25 means it is too low.Admission manifold air temperature sensor controls the signal voltage to ECM with a thermistor(see as Figure 18). ECM imposes a reference voltage(4~6V) on a sensor in No.427 circuit, when the air temperature is low, the resistance of the sensor (thermistor) is high, so ECM will get a high signal voltage. As the air gets warmer, the resistance of the sensor is getting lower, and the voltage is getting lower.   (View)

Transmitter: the relay K and SCR VS are used to control the power of transmitter circuit. IC1 forms alarm sound signal circuit. The transistor V and its peripheral components form RF oscillator circuit to transmit the alarm signal. When the circuit is in the waiting state, the switch S1 is connected, and SB1 is disconnected(the front lock is locked), K is in the release state, the alarm transmitter does not work. When the front lock is opened (SB1 is connected), VS is triggered and turned on, K pulls in, the transmitter gets power. When SB1 is switched on, the normal open point of K-2 will be self-locking, at this time, the S1 being disconnected can stop the alarm.   (View)
