AT2–89 A340E (2JZ—GTE) AUTOMATIC TRANSMISSION – TROUBLESHOOTING DTC 67 O D Direct Clutch Speed Sensor Circuit CIRCUIT DESCRIPTION O/D Direct Clutch Drum This sensor detects the rotation speed of the O/D input shaft from the rotation of the O/D direct clutch drum. Its construction is the same as that of the No.2 vehicle speed sensor (See page AT2–79). By comparing the O/D direct clutch speed signal and the No.2 vehicle speed sensor signal, the ECM detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure in response to various conditions, thus performing smooth gear shift. O/D Direct Clutch Speed Sensor AT5609 DTC No. | Diagnostic Trouble Code Detection Condition | Trouble Area All conditions below are detected for 4 secs. or more.
