DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
No.
6 CHECK HARNESS BETWEEN ECM AND
COMBINATION METER.
Measure resistance between ECM and combi-
nation meter connector.
Connector & terminal
(B135) No. 25 — (i11) No. 1:
7 CHECK FUEL TANK CORD.
1) Turn ignition switch to OFF.
2) Disconnect connector from fuel sub level
sensor.
3) Measure resistance between fuel sub level
sensor and chassis ground.
Connector & terminal
(R59) No. 1 — Chassis ground:
8 CHECK FUEL TANK CORD.
1) Disconnect connector from fuel pump
assembly.
2) Measure resistance between fuel pump
assembly and chassis ground.
Connector & terminal
(R59) No. 2 — Chassis ground:
9 CHECK FUEL LEVEL SENSOR.
1) Remove fuel pump assembly. <Ref. to
FU(DOHC TURBO)-60, Fuel Pump.>
2) Measure resistance between fuel level sen-
sor and terminals with its float set to the full
position.
Terminals
No. 3 — No. 5:
10 CHECK FUEL SUB LEVEL SENSOR.
1) Remove fuel sub level sensor. <Ref. to
FU(DOHC TURBO)-63, Fuel Sub Level Sen-
sor.>
2) Measure resistance between fuel sub level
sensor and terminals with its float set to the
full position.
Terminals
No. 1 — No. 2:
Step

1 MΩ?
Is the resistance between
0.5 and 2.5 Ω?
Is the resistance between
0.5 and 2.5 Ω?
EN(DOHC TURBO)-213
Check Yes
Repair or replace
combination
meter. <Ref. to
IDI-4, Combina-
tion Meter Sys-
tem.>
Go to step 8.
Go to step 9.
Go to step 10.
Repair poor con-
tact in harness
between ECM
and combination
meter connector.
Engine (Diagnostics)
No
