4-58 FI SYSTEM DIAGNOSIS
6) Disconnect the ECM coupler.
7) Check the continuity between Bl/Y wire
B
and terminal
J
.
8) Also, check the continuity between B/Br wire
C
and terminal
T
.
STPS lead wire continuity: Continuity (
)
09900-25008: Multi circuit tester set
09900-25009: Needle-point probe set
Tester knob indication: Continuity test (
)
Is the continuity OK?
Step 1 (When indicating P1654-L:)
1) Turn the ignition switch OFF.
2) Lift up the fuel tank by removing the fuel tank mounting bolt.
(
5-3)
3) Check the STP sensor coupler for loose or poor contacts.
If OK, then check the STP sensor lead wire continuity.
4) Disconnect the STP sensor coupler.
5) Check the continuity between Bl/Y wire
B
and ground.
6) Also, check the continuity between Bl/Y wire
B
and B/Br wire
C
. If the sound is not heard from the tester, the circuit condi-
tion is OK.
7) Disconnect the ECM coupler.
8) Check the continuity between R wire
A
and terminal
A
.
9) Also, check the continuity between Bl/Y wire
B
and terminal
J
.
