P0183
DTC P0183 FTT SENSORComponent Description
The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank. The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the fuel temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
CAUTION: Do not use ECM ground terminals when measuring input/ output voltage. Doing so may result in damage to the ECM s transistor. Use a ground other than ECM terminals, such as the ground.
DTC Confirmation Procedure
NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT-II.
3. Wait at least 10 seconds.
If the result is NG, go to "Diagnostic Procedure" below.
If the result is OK, go to following step.
4. Check "COOLAN TEMP/S" value. If "COOLAN TEMP/S" is less than 60°C (140°F), the result will be OK. If "COOLAN TEMP/S" is above 60°C (140°F), go to the following step.
5. Cool engine down until "COOLAN TEMP/S" is less than 60°C (140°F).
6. Wait at least 10 seconds.
7. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.
WITH GST
Follow the procedure "With CONSULT-II" above.
