1) Remove the air cleaner box. (
$
6-10)
2) Turn the ignition switch to OFF.
3) Check the TO sensor coupler for loose or poor contacts.
If OK, then measure the TO sensor resistance.
4) Remove the TO sensor.
5) Disconnect the TO sensor coupler.
6) Measure the resistance between terminal
A
and terminal
B
.
&
TO sensor resistance: 19.0 – 20.0 k
Ω
(Terminal
A
– Terminal
B
)
