Toyota Camry (XV70): Torque Converter Clutch Actuator Stuck On (P07407E)
DESCRIPTION
The ECM uses signals from the throttle position sensor, mass air flow meter, transmission revolution sensor (NT), transmission revolution sensor (NC) and crankshaft position sensor to help determine the engagement timing of the lock-up clutch. The ECM monitors the engagement of the clutch using the transmission revolution sensor (NT), transmission revolution sensor (NC) and crankshaft position sensor.
Then the ECM compares the engagement condition of the lock-up clutch with the lock-up schedule in the ECM memory to detect solenoid (SL) valve, transmission valve body assembly and torque converter assembly mechanical problems.
