P1D6F – Generator Motor Temperature Sensor Circuit Range/Performance

 

P1D6F Possible Symptoms

 

Engine Light ON (or Service Engine Soon Warning Light)

 

P1D6F Possible Causes

 

Faulty Generator Motor Temperature Sensor,Generator Motor Temperature Sensor harness is open or shorted,Generator Motor Temperature Sensor circuit poor electrical connection,Faulty Motor Control Module (Traction)

 

P1D6F Description

 

The generator motor is cooled by an automatic transmission fluid (ATF)-based oil cooling system and the Motor Control Module (Traction) obtains the ATF temperature and generator motor temperature signals. Normally, the generator motor temperature and the ATF temperature become nearly the same value immediately after the generator motor is started when it is sufficiently cooled down. The motor control module (traction) detects a malfunction and stores a DTC when the difference between the ATF temperature and the generator motor temperature immediately after the generator motor is started is equal to or more than the prescribed value for the prescribed time or more.
