The fuel temperatur sensor (FTS) senses fuel temperature and send it to ECM. Using the signal, ECM decides the fuel injection quantity.
When idling speed is not appropriate or blacksmoke arises it is likely to be a defect of fuel temperature sensor.
Refer to P0182, P0183 DTC inspection procedures.
Remove the fuel temperature sensor.
With the temperature sensing portion of the fuel temperature sensor immersed in hot water, check resistance.
Temperature(°C) | Resistance (kΩ) |
-40 | 48.14 |
-20 | 14.13 ~ 16.83 |
0 | 5.790 |
20 | 2.31 ~ 2.59 |
40 | 1.148 |
60 | 0.59 |
80 | 0.32 |
100 | 0.19 |
110 | 0.14 ~ 0.15 |
120 | 0.1163 |
If the resistance deviates from the standard value greatly, replace the sensor.
Apply sealant THREE BOND TB 2403 or equivalent to threaded portion.
Install fuel temperature sensor and tighten it to specified torque.
Tightening torque
20 ~ 40 N·m (14.75 ~ 29.50 Ib·ft)
Connect the harness connector securely.
After running engine, check fuel leak.
