DTC P1752 INPUT CLUTCH SOLENOID VALVE

DTC P1752 INPUT CLUTCH SOLENOID VALVE

Description

INFOID:0000000001282854

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 Value in Data Monitor Mode

INFOID:0000000001282855

On Board Diagnosis Logic

INFOID:0000000001282856

• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1752 I/C SOLENOID/CIRC” with CONSULT-III or 5th judgement flicker without

CONSULT-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 Cause

INFOID:0000000001282857

• Harness or connectors

(The solenoid circuit is open or shorted.)

• Input clutch solenoid valve 

DTC Confirmation Procedure

INFOID:0000000001282858

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-III

1.

Turn ignition switch “ON”. (Do not start engine.)

2.

Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

3.

Start engine.

4.

Drive vehicle and maintain the following conditions for at least 5 consecutive seconds.
ACCELE POS: 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.

5.

If DTC is detected go to 

TM-86, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT-III”.
