DTC P1752 INPUT CLUTCH SOLENOID VALVE
Revision: 2005 July 2005 FX
DTC P1752 INPUT CLUTCH SOLENOID VALVEPFP:31940
DescriptionACS002OW
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-II Reference ValueACS003KS
On Board Diagnosis LogicACS002OX
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P1752 I/C SOLENOID/CIRC” with CONSULT-II or 5th 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 CauseACS002OY
Harness or connectors
(Solenoid circuit is open or shorted.)
Input clutch solenoid valve
DTC Confirmation ProcedureACS002OZ
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
Selector lever: “D” position
Gear position: 3rd 4th Gear (I/C ON/OFF)
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions required for this test.
6. If DTC is detected go to “ AT- 1 5 1 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.

DTC P1754 INPUT CLUTCH SOLENOID VALVE FUNCTIONPFP:31940
DescriptionACS002P1
Input clutch solenoid valve is controlled by the TCM in response to signals sent from the PNP switch, vehi-
cle 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 ValueACS003KI
On Board Diagnosis LogicACS002P2
This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P1754 I/C SOLENOID FNCTN” with CONSULT-II or 5th 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 3 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 3 is irregular
during releasing accelerator pedal. (Other than during shift change)
Possible CauseACS002P3
Harness or connectors
(Solenoid and switch circuits are open or shorted.)
Input clutch solenoid valve
ATF pressure switch 3
DTC Confirmation ProcedureACS002P4
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. Start engine.
2. Accelerate vehicle to maintain the following conditions. ACCELE POSI: 1.5/8 - 2.0/8
Selector lever: “D” position
Gear position: 3rd 4th Gear (I/C ON/OFF)
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.
3. Perform step “2” again.
4. Turn ignition switch OFF, then perform step “1” to “3” again.
5. Check “SELF-DIAG RESULTS” mode for “A/T” with CONSULT- II. If DTC (P1754) is detected, go to AT- 1 5 3 , "
