terminal No. 4.

Normal condition:

4. If the resistance is outside the standard value, or if 

it doesn’t change smoothly, replace the throttle 
position sensor.

1. Disconnect the oxygen sensor connector and 

connect the special tool Test harness 
(MD998464) to the connector on the oxygen 
sensor side.

2. Make sure that there is continuity (4.5

C) between terminal No. 1 (red clip of special 

tool) and No. 3 (blue clip of special tool) on the 
oxygen sensor connector.

3. If there is no continuity, replace the oxygen 

sensor.

4. Warm up the engine until engine coolant is 80

•

C 

or higher.

5. Perform a tracing for 5 minutes or more with the 

engine speed of 4,500 r/min.

6. Connect a digital voltage meter between terminal 

No. 2 (black clip of special tool) and No. 4 (white 
clip of special tool).

7. While repeatedly racing the engine, measure the 

oxygen sensor output voltage.

Standard value:

CAUTION

œ

Be very careful when connecting the jumper 
wire; incorrect connection can damage the 
oxygen sensor.

œ

Be careful the heater is broken when voltage 
of beyond 8V is applied to the oxygen sensor 
heater.

NOTE: If the sufficiently high temperature (of 
approximate 400

•

C or more) is not reached 

although the oxygen sensor is normal, the output 
voltage would be possibly low although the rich 
air-fuel ratio. Therefore, if the output voltage is 
low, use a jumper wire to connect the terminal 
No.1 (red clip of special tool) and the terminal No. 
3 (blue clip of special tool) of the oxygen sensor 
with a (+) terminal and (-) terminal of 8 V power 
supply respectively, then check again.

8. If the sensor is defective, replace the oxygen 

sensor.

NOTE: For removal and installation of the oxygen 
sensor, refer to GROUP 15

 Exhaust Manifold.
