• 2.DEF: VOLTAGE TOO HIGH
• 3.DEF: SIGNAL INCOHERENCE
• 4.DEF: IMPROPER SIGNAL 

SHAPE

• 5.DEF: INTERMITTENT SIGNAL 

INCOHERENCE

• 6.DEF: NO SIGNAL SPECIFIC 

SUBTYPE 

• An excessively low voltage from the 

sensor is sent to ECM.

• An excessively high voltage from 

the sensor is sent to ECM.

• An excessively difference between 

minimum and maximum fuel tem-
perature signal from the sensor is 
sent to ECM while engine running.

• ECM detects improper fuel tempera-

ture signal.

• Harness or connectors
