FTT SENSOR [Fuel tank temperature (FTT) sensor circuit range/performance] |
A) |
Diagnosis condition |
-- |
|
Signal (terminal) |
FTT sensor signal |
|||
|
Threshold |
Rationally incorrect voltage from the sensor is sent to ECM, compared with the voltage signals from ECT sensor 1 and intake air temperature sensor |

|
B) |
Diagnosis condition |
Engine is started with its cold state |
||
|
Signal (terminal) |
FTT sensor signal |
|||
|
Threshold |
The comparison result of signals transmitted to ECM from each temperature sensor (IAT sensor, ECT sensor 1, EOT sensor, and FTT sensor) shows that the voltage signal of the FTT sensor is higher/lower than that of other temperature sensors |
