P1755
DTC P1755 Linear Solenoid For Lock-Up Control Circuit Malfunction (Shift Solenoid Valve SLU)
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 noncontinuity, then
(*) Duty Ratio = A/A+B x 100(%)
