Component Location

General Description

PCM control Pressure control solenoid valve by changed current for reducing shift shock.

DTC Description

This code is set when circuit open or short detected by PCM.

DTC Detecting Condition

Item	Detecting Condition	Possible Cause
DTC Strategy	• Monitoring voltage range(Circuit open/short check)	※ Pressure Control Solenoid Valve : PCSV(LP. VFS) • Circuit open or short • PCSV • PCM
Enable Conditions	• Completely opened or closed • Gaer tightening • After change of speed > 0.3sec • 10V < Solenoid supplied power < 16V
Threshold value	• 50mA ≤ Feedback current(Circuit short) ≤ 550mA at operating • 50mA > Feedback current (Circuit open ) at operating
Detecting Time	• More than 0.2sec
Fail safe	• Locked into 4th gear
