P0183

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

F1 : CHECK THE FUEL TEMPERATURE SENSOR RESISTANCE
1. Disconnect the FT sensor electrical connector, PI27.
2. Measure the resistance between pins 1 and 2 of the FT sensor.

Is the resistance 37.35 ohms at 20 degrees C?

Yes
Goto F2

No
Install a new Fuel Temperature Sensor.CLEAR the DTCs. TEST the system for normal operation.

F2 : 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 PI27.
3. Disconnect the PCM electrical connector PI01.
4. Measure the resistance between the fuel temperature sensor electrical connector PI27, pin 2 (YR) and the PCM electrical connector PI01, pin 50 (YR).

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 GROUND CIRCUIT
1. Measure the resistance between the fuel temperature sensor electrical connector PI27 pin 1 (BG) and GROUND.

Is the resistance less than 5 ohms?

Yes
Goto F4

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

F4 : CHECK THE FUEL TEMPERATURE SENSOR CIRCUIT FOR A SHORT TO GROUND
1. Measure the resistance between the fuel temperature sensor electrical connector PI27 pin 2 (YR) 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 F5

F5 : CHECK THE FUEL TEMPERATURE SENSOR GROUND CIRCUIT FOR A SHORT TO BATTERY
1. Disconnect the FT sensor electrical connector, PI27.
2. Turn the ignition switch to the ON position.
3. Check for a voltage between PI27, pin 1 (BG) and GROUND.

Is a voltage present?

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 F6

F6 : CHECK THE FUEL TEMPERATURE SENSOR CIRCUIT FOR A SHORT TO BATTERY POSITIVE
1. Connect the PCM electrical connector PI01.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between the fuel temperature sensor electrical connector PI27, pin 2 (YR) and GROUND.

Is the voltage greater than 10 volts?

Yes
Repair the short to battery positive. 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.
