DTC P0181 FTT SENSOR
Revision: 2006 November2007 350Z
Diagnostic ProcedureNBS0007C
1. CHECK DTC WITH “UNIFIED METER AND A/C AMP.”
Refer to DI-47, "
SELF-DIAGNOSTIC RESULTS" .
OK or NG
OK >> GO TO 2.
NG >> Go to DI-19, "
Fuel Level Sensor Signal Inspection" .
2. CHECK FUEL TANK TEMPERATURE SENSOR POWER SUPPLY CIRCUIT
1. Disconnect “fuel level sensor unit and fuel pump” harness con-
nector.
2. Turn ignition switch ON.
3. Check voltage between “fuel level sensor unit and fuel pump”
terminal 4 and ground with CONSULT-III or tester.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING PART
Check the following.
Harness connectors B1, M12
Harness for open or short between ECM and “fuel level sensor unit and fuel pump”
>> Repair open circuit or short to ground or short to power in harness or connector.
4. CHECK FUEL TANK TEMPERATURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect “unified meter and A/C amp.” harness connector M49.
3. Check harness continuity between “fuel level sensor unit and fuel pump” terminal 5 and “unified meter and
A/C amp.” terminal 36. Refer to Wiring Diagram.
4. Also check harness for short to power.
OK or NG
OK >> GO TO 6.
NG >> GO TO 5.
