Hyundai Santa Fe: Hydraulic System / Line Pressure Control Solenoid Valve (LINE_VFS). Repair procedures
| •
|
Refer to the DTC manual for the check procedure.
|
|
| •
|
Be careful not to damage the parts located under the vehicle
(floor under cover, fuel filter, fuel tank and canister) when
raising the vehicle using the lift.
(Refer to General Information - "Lift and Support Points")
|

|
When the solenoid valve Diagnostic Trouble Codes (DTC) is on,
perform the following procedure to replace it.
|
| •
|
Automatic transaxle is composed of delicate components. Be careful
not to cause any damage on the component in the course of assembly
and disassembly.
|
| •
|
Maintain clean condition so that foreign substance does not
get into the automatic transaxle.
|
| •
|
Use a coated apron, latex gloves, and stainless tray to prevent
foreign substance from getting into the transaxle.
|

|
Automatic transaxle fluid (ATF) can be reused. Collect it using
a clean 10-liter beaker.
|
|
|
1. |
Turn ignition switch OFF and disconnect the negative (-) battery cable.
|
|
2. |
Remove the air duct and the air cleaner assembly.
(Refer to Engine Mechanical System - "Air Cleaner")
|
|
3. |
Separate the air bleed hose (B) and then wiring bracket (A).
|
|
4. |
Remove the under cover.
(Refer to Engine Mechanical System - "Engine Room Under Cover")
|
|
5. |
Remove the drain plug (A) and reinstall the drain plug after draining
ATF totally.
|
Drain plug tightening torque :
33.3 - 43.1 N.m (3.4 - 4.4 kgf.m, 24.6 - 31.8 lb-ft)
|
|
• |
Replace the gasket before reinstalling the drain plug.
|
|
|
|
6. |
Loosen the mounting bolts (A) of the valve body cover.
|
Tightening torque :
11.8 - 13.7 N.m (1.2 - 1.4 kgf.m, 8.7 - 10.1 lb-ft)
|
|
• |
Be careful when removing the valve body cover because
the remaining ATF remains in the valve body cover.
|
|
|
• |
Replace the gasket (A) before reinstalling the valve
body cover.
|
|
• |
After the installation, start the engine and then check
if there are any leakages from the valve body cover.
|
|
|
|
7. |
Loosen the bolts and then removing the main harness (A).
|
Tightening torque :
9.8 - 11.8 N.m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb-ft)
|
|
|
8. |
Loosen the bolts and then removing the support bracket (A).
|
Tightening torque :
9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft)
|
|
|
9. |
Remove the line pressure control solenoid valve (A).
|
|
1. |
To install, reverse the removal procedure.
|
|
2. |
Inject the automatic transaxle oil and inspect the oil level.
(Refer to Automatic Transaxle System - "Automatic Transaxle Fluid")
|
• |
After ATF level check or exchange, be sure to remove
residual ATF on transaxle case.
(Be especially sure to remove residual ATF between automatic
transaxle case and valve body cover)
|
|
• |
After installing the valve body cover, make sure to
check the oil leakage at the connection area with the
engine ON
|
|
|
|
3. |
Clear the diagnostic trouble codes (DTC) using the diagnostic tool.
(Refer to Automatic Transaxle System - "Automatic Transaxle")
|
• |
Even though disconnecting the battery negative terminal,
the DTCs will not be cleared. So, be sure to clear the
DTCs using the diagnostic tool.
|
|
|
|
4. |
In order to prevent start delay and gear shift shock during acceleration
and start, perform TCM learning after replacing the solenoid valve.
