DescriptionECS00FZW
lInput clutch solenoid valve is controlled by TCM in response to signals sent from PNP switch, vehicle
speed sensor and accelerator pedal position sensor. Gears will then be shifted to the optimum position.
lThis is not only caused by electrical malfunction (circuits open or shorted) but also by mechanical mal-
function such as control valve sticking, improper solenoid valve operation.

On Board Diagnosis LogicECS00FZY
Diagnostic trouble code “P1754 I/C SOLENOID FNCTN” with CONSULT-II or 5th judgement flicker without
CONSULT-II is detected under the following conditions.
lWhen TCM detects that actual gear ratio is irregular, and relation between gear position and condition of
ATF pressure switch 3 is irregular during depressing accelerator pedal. (Other than during shift change)
lWhen TCM detects that relation between gear position and condition of ATF pressure switch 3 is irregular
during releasing accelerator pedal. (Other than during shift change)
Possible CauseECS00FZZ
