5) Measure the resistance between terminal and terminal .
TO sensor resistance: 16.5 – 22.3 k
Ω
(Terminal – Terminal )

Is the resistance OK?
Step 1 (When indicating P1651-H:)
1) Turn the ignition switch OFF.
2) Lift and support the fuel tank. (
5-3)
3) Check the TO sensor coupler for loose or poor contacts.
If OK, then check the TO sensor lead wire continuity.
4) Disconnect the TO sensor coupler.
5) Check the continuity between R wire
and B wire .
If the sound is not heard from the tester, the circuit condition
is OK.
6) Disconnect the ECM coupler.
7) Check the continuity between B wire
and terminal

8) Also, check the continuity between B/Br wire and terminal
:
