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.

INJECTOR CHECK
