tube  inside.  The  working  of  oxygen  sensor  is 
carried  out  by  transferring  the  concentration 
difference  of  the  oxygen  ion  outside  of ceramic 
tube  to  voltage  (100mv

900mv)signal  and 

output. 

5)Working voltage

Malfunction:

  badness  idle  speed,  badness 

acceleration,  badness  tail  gas,  over  fuel 
consume etc. 

l

 

Reason: 

1,  moisture  entering  inside  of 

sensor,  and  when  the  temperature  is 
changed 

pin 

is 

broken; 

2, 

sensor

Notice:

 it is forbidden to use cleaning liquid, 

oiliness  liquid  or  volatility  solid  during 
service.

Measuring  method: 

a)  disassemble  joint, 

put digital  multimeter to ohm shift, connect 
meter  pen  to  No.1(white)  and  No.2(white) 
pins  of  the  sensor.  Normally  the  resistance 
value  is  1~6

Ω

.  b)  Connect  the  joint  and 

keep  it  at  idle  speed  status.  When  the 
oxygen  sensor  reaches  to  its  working 
temperature  350

℃

,  keep  digital  multimeter 

to  DC  volt  shift  and  connect  meter  pen  to 
No.3 (gray) and No.4 (black) pins of sensor. 
Now  the  voltage  should  be  fluctuate 
between  0.1-  0.9V  quickly  (the  data  also 
can  be  gotten  from  data  flow  inspected  by 
diagnosis meter).
