2. Make sure that there is continuity (11 - 18 W at 20_C)
(rear)
between terminal 3 and terminal 4 on the oxygen sensor
connector.
3. If there is no continuity, replace the oxygen sensor.
NOTE
(1) If the MUT-II does not display the standard value
although no abnormality is found by the above
mentioned continuity test and harness check, replace
the oxygen sensor (rear).

2. Measure the resistance between terminals.
Standard value: 13 - 16 W (at 20_C)
3. Install the injector connector.
Checking the Injection Condition
1. Following the steps below, bleed out the residual pressure
within the fuel pipe line to prevent flow of the fuel.
