FUEL SYSTEM
TERMINAL AND CONNECTOR INSPECTION
E015498F
1.
Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various prob-
lems and damge of component.
2.
Perform checking procedure as follows.
1)
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
2)
Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking
device and connecting condition between terminal and wiring.
NOTE
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector or
checking connecting condition. ( after checking, reconnect the pin at correct position. )
3.
Is the problem found?
YES
▶
Repair the trouble causing part and go to "Verification of Vehicle Repair".
NO
▶
Go to "Component Inspection".
COMPONENT INSPECTION
E274811D
1.
Check VGT actuator component resistance
1)
IG KEY "OFF", ENGINE "OFF"
2)
Disconnect VGT actuator connector.
3)
Measure the resistance between VGT actuator component terminal 1 and 2.
Specification : 14.7 ~ 16.1

4)
Is VGT actuator component resistance within the specification?
YES
▶
Go to "2.Check VGT actuator operation" as follows.
NO
▶
Replace VGT actuator and go to "Verification of Vehicle Repair".
DTC TROUBLESHOOTING PROCEDURES
FL -255
2.
Check VGT actuator operation
1)
IG KEY "ON", ENGINE "ON".
2)
Check that VGT actuator operating duty is 76% after warming engine up.
3)
Check if vacuum generates after disconnecting VGT valve vacuum hose.
4)
Check if vacuum generates when decelerating after rapid acceleration (Vacuum must not generates, correct VGT
actuator operating duty is 45%).
Specification : VGT actuator duty 76% : vacuum generates
VGT actuator duty 45% : vacuum does not generate
YES
▶
Go to "Verification of Vehicle Repair".
NO
▶
Replace VGT actuator and go to "Verification of Vehicle Repair".
※
Repeat this process 2~3 times.
VERIFICATION OF VEHICLE REPAIR
E4067EAA
After a repair, it is essential to verify that the fault is corrected.
1.
After connecting Scantool select "DIAGNOSTIC TROUBLE CODES(DTCs)" mode.
2.
Clear recorded DTC using Scantool.
3.
Drive the vehicle within DTC "Enable conditions" in "General information".
4.
After selecting "DIAGNOSTIC TROUBLE CODES(DTCs)" mode and check if DTC is recorded again.
5.
Are any DTCs recorded ?
YES
▶
Go to the DTC guide of recorded NO. in Scantool.
NO
▶
System operates within specification.

DTC P0335 CRANKSHAFT POSITION SENSOR A CIRCUIT
COMPONENT LOCATION
E5A3953F
CKPS
OPS
LFIG287A
GENERAL DESCRIPTION
EE023A66
Crank Shaft Position Sensor(CKPS) is magnetic inductive type. Mounted on transaxle hausing, it senses tone wheel
position of fly wheel.As tone wheel is devided with 58 teeth and 2 missing teeth (referrence point), 1 tooth corresponds
to 6 degree.CKPS which calculates RPM and crank angle is important to determine fuel injection quantity and injection
timing with APS.crank shaft position is closely related to engine starting.
DTC DESCRIPTION
E39484BC
P0335 is set when CKPS signal does not generate for more than 0.7 sec. while CMPS signal is outputted. This code
is due to CKPS circuit or component failure. If CKPS signal is not inputted during driving, RPM is calculated based on
CMPS signal.
DTC DETECTING CONDITION
E9232897
Item
Detecting Condition
Possible Cause
DTC Strategy
• Signal monitoring
Enable Conditions
• During accelerating and turning engine "ON"
Threshold Value
• CMPS signal is outputted while CKPS signal
does not generate.
Diagnostic Time
• tone wheel rotates 4 times
Fuel cut
YES
EGR Off
NO
Fuel Limit
NO
Fail Safe
Check
Lamp
YES
• RPM is considered as double
speed of CAM rotation.
• CKPS circuit
• CKPS component
• Abnormal deformation of
