HUBER EGR
SYSTEM DESCRIPTION The following chart shows the relationship between the input and the output in Huber EGR control unit. Compared to traditional system that only operates theEGR valve with RPM sensor and Micro switch, the HuberEGR control unit bring big differences that of traditionalsystem on the functions.
Input Signal
RPM sensor (CPS)
EGR valve lift sensor
Throttle position sensor (TPS) - M/T
Shift lever position
Throttle position sensor (TPS)
Vehicle speed sensor(VSS) Basic input signal for EGR operation Engine cold or hot signal
Position signal of EGR valve that is triggered by vacuum modulator 1 Transfer the engine load signal to the control unit directly (manual transmission)
TCU (A/T)
EGR
Control
Unit
Coolant temperature sensor (CTS)
Solenoid valve (Control forvacuum modulator 2)
If the control unit determines it is in no-load sharp accel- eration mode after analyzing the input signals, this conver- sion type switch reduces the fuel consumption by cutting off the intake air pressure from
fuel injection ALDA and gen- erating the vacuum pressure. In no-load sharp acceleration
mode, Duty Control ( continu- ous precise control) is acti- vated according to the varia- tions of the input signals when the solenoid valve generates the vacuum pressure in ALDA.
Vacuum modulator 2
The opening value of the modulator is precisely con- trolled by input signals and programmed MAP, and the opening value of EGR valve is also changed by the varia- tions of vacuum pressure to EGR valve. The changed opening value is transferred to the control unit as input signal.
Vacuum modulator 1
TCU in automatic transmission equipped vehicle transfers the information such as driving conditions and speeds into the EGR control unit. EGR control unit uses the shift lever position and vehicle speed as important information for operating the solenoid valve during no-load sharp acceleration mode. In manual transmission, the signal of vehicle speed is transferred into the EGR control unit directly.
Clutch switch
In manual transmission, the clutch switch is the one of core elements to determine driving condition. Output Signal

Coolant Temperature Sensor (CTS)
1. Location: on cylinder block
2. Coolant temperature MAP (4 Stages) T0: 10 ~ 24 °C
T1: 25 ~ 40 °C
T2: 41 ~ 61 °C
T3: above 61 °C
3. If the EGR system is normally defective while engine is cold (or during warming up), it may be caused by incorrect input signal of the coolant temperaturesensor.
4. Resistance between pin 1 and pin 4 of the connector 20 °C: 2250 ± 159.0
50 °C: 836 ± 41.5
80 °C: 321 ± 15.0
120 °C: 113 ± 7.2
KAA5A040 KAA5A060
KAA5A060Solenoid Valve
1. This valve is used in no-load sharp acceleration mode.
2. Solenoid valve (Normal Open type)


 Normal: Solenoid valve opens, then intake
manifold pressure will operate ALDA.


 No-load sharp acceleration mode: Solenoid valve
closes, then vacuum pressure operate ALDA.
3. Operating voltage: approx. 12 V
4. Resistance: approx. 22.4 ± 1.4
5. Check the connections in each passage when supplying or cutting off the operating voltage.
The valve passage to ALDA will be changed when the battery voltage is supplied through EGR control unit.
Changed to ALDA (1 to 3) or vacuum from intake manifold
Changed to ALDA (2 to 3) from modulator 2 (Refer to exhaust gas control mode with no-load sharp acceleration)
