DTC P1752 INPUT CLUTCH SOLENOID VALVEPFP:31940
DescriptionNCS0005C
Input clutch solenoid valve is controlled by the TCM in response to signals sent from the PNP switch, vehicle
speed sensor and accelerator pedal position sensor (throttle position sensor). Gears will then be shifted to the
optimum position.
CONSULT-III Reference ValueNCS0005D
On Board Diagnosis LogicNCS0005E

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P1752 I/C SOLENOID/CIRC” with CONSULT-III or 5th judgment flicker CON-
SULT-III is detected under the following conditions.
–When TCM detects an improper voltage drop when it tries to operate the solenoid valve.
–When TCM detects as irregular by comparing target value with monitor value.
Possible CauseNCS0005F

Harness or connectors
(Solenoid circuit is open or shorted.)
