SFI SYSTEM (1ZZ–FE/3ZZ–FE)
Using an ohmmeter, measure the resistance be-
tween terminals.
Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
Check that there is no continuity between terminals
3 and 5.
Apply battery voltage across terminals 1 and 2.
Using an ohmmeter, check that there is continuity
between terminals 3 and 5.
