P0183

DTC P0183: Fuel Temperature Sensor Circuit High Voltage (2004-2005 models)

NOTE: Information marked with an asterisk (*) applies to 2004-2005 models.

1. Reset the PCM.
2. Turn the ignition switch ON (II).

Is DTC P1183 (P0183)* indicated?

YES - Go to step 3.

NO - Intermittent failure. The system is OK at this time. Check for poor connections or loose terminals at the fuel temperature sensor and at the PCM.

3. Turn the ignition switch OFF.
4. Disconnect the fuel temperature sensor 2P connector.







5. Measure resistance between fuel temperature sensor 2P connector terminals No.1 and No.2

Is the resistance OK (see the graph)?

YES - Go to step 6.

NO - Replace the fuel temperature sensor.

6. Turn the ignition switch OFF.
7. Disconnect PCM connector E (31P).




8. Connect fuel temperature sensor 2P connector terminals No.1 and No.2 with a jumper wire.




9. Check for continuity between PCM connector terminals A10 and E17.

Is there continuity?

YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck.
If the symptom/indication goes away with a known-good PCM, replace the original PCM.

NO - Go to step 10.




10. Connect fuel temperature sensor 2P connector terminal No.1 to body ground with a jumper wire.




11. Check for continuity between PCM connector terminal A10 and body ground.

Is there continuity?

YES - Repair open in the wire between the PCM (E17) and the fuel temperature sensor.

NO - Repair open in the wire between the PCM (A10) and the fuel temperature sensor.
