5) Turn ignition switch to ON.
6) Measure voltage between fuel pump connector and
chassis ground.
: Connector & terminal
(R58) No. 6 (+)—Chassis ground ():
Is the voltage more than 10 V?
: Repair battery short circuit in harness between
ECM and fuel pump connector.
: Go to step11W3.

11W3CHECK HARNESS BETWEEN FUEL TEM-
PERATURE SENSOR AND ECM CON-
NECTOR.
1) Measure voltage between fuel pump connector and
chassis ground.
: Connector & terminal
(R58) No. 6 (+)—Chassis ground ():
Is the voltage more than 4 V?
: Go to next step 2).
: Repair harness and connector.
NOTE:
In this case, repair the following:

Open circuit in harness between ECM and fuel pump
connector

Poor contact in fuel pump connector

Poor contact in ECM connector

Poor contact in coupling connectors (B97 and R57)

2) Turn ignition switch to OFF.
3) Measure resistance of harness between fuel pump con-
nector and chassis ground.
: Connector & terminal
(R58) No. 5—Chassis ground:
Is the resistance less than 5Ω?
: Replace fuel temperature sensor.
: Repair harness and connector.
NOTE:
In this case, repair the following:

Open circuit in harness between ECM and fuel pump
connector

Poor contact in fuel pump connector

Poor contact in ECM connector

Poor contact in coupling connectors (B22, B97 and R57)
