Supra L6-2997cc 3.0L DOHC MFI (1998)
A.
The Diagnostic Tester displays 17" as a value of the Time $81" (see illustration).
B.
Find the Conversion Factor value of Time $81" in the O2S Failure Threshold chart. 0.3906 is specified for Time $81 in this chart.
C.
Multiply "17" in step "A" by 0.3906 (Conversion Factor) in step "B."
17 x 0.3906 = 6.6%
D.
If the answer is within the Standard Value of TEST LIMIT, the Time $81" can be confirmed to be normal.
NOTE:
^
"LOW SW V" indicates the O2S voltage when the O2S status changes from rich to lean.
^
"HIGH SW V" indicates the O2S voltage when the O2S status changes from lean to rich.
^
If the O2S voltage is lower than "LOW SW V," the O2S status is lean.
^
If the O2S voltage is higher than "HIGH SW V," the O2S status is rich.
NOTE:
Before the O2S Monitor completes or after the ignition switch is turned OFF, the Diagnostic Tester displays the viewable upper limit or a
lower limit of the test value (example: 0 V, 1.275 V, Os [seconds], 10.2s, 0 and 255).
