ECM uses signals from TP sensor, airflow meter and crankshaft position sensor to monitor torque converter clutch lock-up engagement condition. ECM compares torque converter clutch lock-up engagement condition with lock-up schedule in ECM memory to detect a malfunction with valve body, torque converter clutch or shift solenoid (DSL). Shift solenoid (DSL) controls hydraulic pressure acting on lock-up relay valve, which contains torque converter clutch lock-up. Shift solenoid (DSL) is located on transaxle valve body. See Figure.
