7. While repeatedly racing the engine, measure the oxygen
sensor output voltage.
Standard value:
Engine Oxygen sensor
output voltage
Remarks
When
racing the
engine
0.6 ± 1.0 V If you make the air/fuel ratio
rich by racing the engine
repeatedly, a normal oxy-
gen sensor will output a
voltage of 0.6 ± 1.0 V.
8. If the sensor is defective, replace the oxygen sensor.
NOTE
For removal and installation of the oxygen sensor, refer
to GROUP 15 ± Exhaust Pipe and Main Muffler.
