P0183

F : DTC P0181, P0182, P0183. FUEL TEMPERATURE SENSOR

F1 : CHECK CONTINUITY OF THE FUEL TEMPERATURE SENSOR POWER SUPPLY CIRCUIT

1. Turn the ignition switch to the OFF position.
2. Disconnect the fuel temperature sensor electrical connector IJ8.
3. Disconnect the PCM electrical connector EN16.
4. Measure the resistance between the fuel temperature sensor electrical connector IJ8, pin 2 (WU) and the PCM electrical connector EN16, pin 50 (WU).

Is the resistance less than 5 ohms?
Yes
Goto F2

No
REPAIR the circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

F2 : CHECK THE FUEL TEMPERATURE SENSOR GROUND CIRCUIT

1. Measure the resistance between the fuel temperature sensor electrical connector IJ8 pin 1 (NU) and GROUND.

Is the resistance less than 5 ohms?
Yes
Goto F3

No
REPAIR the circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

F3 : CHECK THE FUEL TEMPERATURE SENSOR CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between the fuel temperature sensor electrical connector IJ8 pin 2 (WU) and GROUND.

Is the resistance less than 10,000 ohms?
Yes
REPAIR the short to GROUND. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
Goto F4

F4 : CHECK THE FUEL TEMPERATURE SENSOR GROUND CIRCUIT FOR A SHORT TO BATTERY

1. Disconnect the FTP sensor electrical connector, FT1.
2. Turn the ignition switch to the ON position.
3. Check for a voltage between FT1, pin 3 (BG) and GROUND.

Is the voltage greater than 1 volt?
Yes
REPAIR the short to battery. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
Goto F5

F5 : CHECK THE FUEL TEMPERATURE SENSOR CIRCUIT FOR A SHORT TO BATTERY

1. Connect the PCM electrical connector EN16.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between the fuel temperature sensor electrical connector IJ8, pin 2 (WU) and GROUND.

Is the voltage greater than 10 volts?
Yes
REPAIR the short to battery. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for normal operation.

No
INSTALL a new fuel temperature sensor. CLEAR the DTCs. TEST the system for normal operation. If the DTC is repeated, INSTALL a new PCM. Before replacing a PCM, contact Dealer technical support.
