DTC P1755 Linear Solenoid for Lock-up Control Circuit Malfunction





CIRCUIT DESCRIPTION
The amount of current flow to the solenoid is controlled by the (*) duty ratio of the ECM output signal. The higher the duty ratio becomes, the higher the lock-up hydraulic pressure becomes during the lock-up operation.





(*) Duty Ratio
The duty ratio is the ratio of the period of continuity in one cycle. For example, if A is the period of continuity in one cycle and B is the period of non-continuity, then

(*) Duty Ratio = A/A+B * 100 (%)
