DTC P1762 DIRECT CLUTCH SOLENOID VALVEPFP:31940
DescriptionNCS001NT
Direct 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-II Reference ValueNCS001NU
On Board Diagnosis LogicNCS001NV
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P1762 D/C SOLENOID/CIRC” with CONSULT-II or 2nd judgement flicker without
CONSULT-II 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 CauseNCS001NW
Harness or connectors
(Solenoid circuit is open or shorted.)
Direct clutch solenoid valve
DTC Confirmation ProcedureNCS001NX
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T”
with CONSULT-II.
3. Touch “START”.
4. Start engine.
5. Drive vehicle and maintain the following conditions for at least 5
consecutive seconds.
ACCELE POSI: 1.5/8 - 2.0/8
SLCT LVR POSI: “D” position
GEAR: “1”

DescriptionNCS001NZ
Direct 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.
This 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.
CONSULT-II Reference ValueNCS001O0
On Board Diagnosis LogicNCS001O1
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P1764 D/C SOLENOID FNCTN” with CONSULT-II or 2nd judgement flicker with-
out CONSULT-II is detected under the following conditions.
–When TCM detects that actual gear ratio is irregular, and relation between gear position and condition of
ATF pressure switch 5 is irregular during depressing accelerator pedal. (Other than during shift change.)
–When TCM detects that relation between gear position and condition of ATF pressure switch 5 is irregular
during releasing accelerator pedal. (Other than during shift change.)
Possible CauseNCS001O2
Harness or connectors
(Solenoid and switch circuits are open or shorted.)
Direct clutch solenoid valve

DTC Confirmation ProcedureNCS001O3
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
