DTC Diagnosis Procedure
CHECK FUEL TANK TEMPERATURE (FTT) SENSOR POWER SUPPLY
-
Turn ignition switch OFF.
-
Disconnect fuel level sensor unit and fuel pump harness connector.
-
Turn ignition switch ON.
-
Check the voltage between fuel level sensor unit and fuel pump harness connector and ground.
+ − Voltage
(Approx.)Fuel level sensor unit and fuel pump Connector Terminal B100 8 Ground 5 V
Is the inspection result normal?
YES>>GO TO 3.
NO>>GO TO 2.
CHECK FUEL TANK TEMPERATURE (FTT) SENSOR POWER SUPPLY CIRCUIT
-
Turn ignition switch OFF.
-
Disconnect ECM harness connector.
-
Check the continuity between fuel level sensor unit and fuel pump harness connector and ECM harness connector.
+ − Continuity Fuel level sensor unit and fuel pump ECM Connector Terminal Connector Terminal B100 8 E21 136 Existed -
Also check harness for short to ground and to power.
Is the inspection result normal?
YES>>Perform the trouble diagnosis for power supply circuit.
NO>>Repair or replace error-detected parts.
CHECK FUEL TANK TEMPERATURE (FTT) SENSOR GROUND CIRCUIT
-
Turn ignition switch OFF.
-
Disconnect ECM connector.
-
Check the continuity between fuel level sensor unit and fuel pump harness connector and ECM harness connector.
+ − Continuity Fuel level sensor unit and fuel pump ECM Connector Terminal Connector Terminal B100 7 E21 155 Existed -
Also check harness for short to power.
Is the inspection result normal?
YES>>GO TO 4.
NO>>Repair or replace error-detected parts.
CHECK FUEL TANK TEMPERATURE (FTT) SENSOR
Check the FTT sensor. Refer to Component Inspection.
Is the inspection result normal?
YES>>Check intermittent incident. Refer to Intermittent Incident.
NO>>Replace “fuel level sensor unit and fuel pump”. Refer to Exploded View.
