Component Location

General Description

Input speed sensor value must be equal Output speed sensor value times each gear ratio at each gear position of trasmission. That operation value equal with TCM operation value. For example Output speed sensor value is 1000RPM and 1st speed gear ratio is 3.670 then Input speed sensor value must be 3670 RPM.

DTC Description

This code is set when Input speed sensor value is different with TCM operation value, caused by control valve sticking, solenoid valve fault(most of fault is mechanical, rarely electrical fault).

DTC Detecting Condition

Item	Detecting Condition	Possible Cause
DTC Strategy	• 1st gear incorrect gear ratio	1. Input speed sensor fault 2. Output speed sensor fault 3. Clutch slip in Transmission
Enable Conditions	• Oil Temperature Sensor >-10℃ • Time after shift changing finish > 1sec. • Engine speed >400rpm • Output speed >200rpm • Input speed > 0rpm • Shift stage 1st. gear • TR switch = "D"range or Sports mode
Threshold value	• 1st : Input speed sensor-Output speed sensor X Gear ratio ≥ 200rpm • 2nd~8th :ㅣInput speed sensor-Output speed sensor X Gear ratio\| ≥ 200rpm
Detecting Time	• More than 1 sec and 4 times
Fail safe	• Locked into 5th gear
