EMS(Engine Management System)

CHECKING FOR A FAULT CODE BY OXYGEN(O

2

)SENSOR HEATER

If the voltage value is abnormal, 

Check to see if the ECU coupler is loose or if there is bad contact.

Check the ‘B/B’’ electric wire, ‘G/W’ electric wire to see if they have been

broken or have short- circuited.

5) If the voltage value is normal, turn off the ignition key. 

Measure the Resistance of oxygen (O2) Sensor heater : about 9[

], about 22

Measuring terminal (side of wire-harness) :  

oxygen(O2)3 terminal of sensor coupler  

(B/BR : BLACK/BROWN) ~

ECU No.34(G/W :GREEN/WHITE)

Remarks : Measuring unit of Resistance : Resistance ‘R’[

]

6) If the measured resistance is abnormal, 

Replace the oxygen(O2)sensor with new one and recheck it. 

If the measured resistance is normal, 

Check the ‘B/B’’ electric wire, ‘G/W’ electric wire to see if they have been

broken or have short- circuited.

If the electric wire is no problem, the ECU is broken. 
Replace the ECU with new one, and recheck it.

CHECKING FOR A FAULT CODE BY OXYGEN(O

2

)SENSOR LAMBDA SIGNAL

1) Turn off the ignition key
2) Check the O2(oxygen) coupler is loose, or bad.

If there is no defect, measure the input voltage of O2(oxygen) 

3) The wire-harness to checck the ECU is connected to the ECU with a coupler. 

refer to the ECU assembly/disassembly (4-34) 

4) Turn on the ignition key
5) Measure the oxygen(O2)sensor voltage of wire harness to check ECU.

Measuring terminal:  

ECU No.12(V :VIOLET)~ 

ECU No.2(V/B:VIOLET/BLACK)

Output voltage of oxygen(O2) sensor : 0.1~0.8[V]

Remark : Measuring unit of voltage : Voltage[V] 

Assembly of oxygen(O2)sensor : 4.08 ~ 6.12[kgf

If the measured voltage is normal, 

Check the ‘B/R’ electric wire, ‘V’ electric wire, ‘V/B’ electric wire to see if they have been broken or
have short- circuited if there is a bad contact  of terminal No. 2, No. 12 of ECU coupler. 
If there is no problem in wires, ECU  is broken.  

Replace the ECU with new one, and recheck it.

If the measured voltage is abnormal,

Check the ‘V’ electric wire, ‘V/B’ electric wire, ‘W/B’ electric wire to see if they have been

broken or have short- circuited.

6) After fault repaired, To erase the memorized fault code in the ECU is refer to how to remove the fault code(5-10)
