2007 KIA CARNIVAL oil

6.Check the mica depth (A). If the mica is too high (B), undercut the mica with a hacksaw blade to the proper depth.
Cut away all the mica (C) between the commutator segments. The undercut should not be too shallow, too narrow,
or v- shaped (D).
Commutator mica depth
Standard (New) : 0.5 mm (0.0197 in.)
Limit : 0.2mm (0.0079 in.)
7.Check for continuity between the segments of the commutator. If an open circuit exists between any segments,
replace the armature.
8.Check with an ohmmeter that no continuity exists between the commutator (A) and armature coil core (B), and
between the commutator and armature shaft (C). If continuity exists, replace the armature.
INSPECT STARTER BRUSH
Brushes that are worm out, or oil - soaked, should be replaced.

INSPECTION
When disconnecting the vacuum hose, make an identification mark on it so that it can be reconnected to its
original position.
1. Disconnect the vacuum hose from the solenoid valve.
2. Detach the harness connector.
3. Connect a vacuum pump to the nipple which is connected to intake manifold.
4. Apply vacuum and check when voltage is applied to the PCSV and when the voltage is discontinued.
Battery voltage Normal condition
When applied Vacuum is released
When discontinued Vacuum is maintained
5. Measure the resistance between the terminals of the solenoid valve.

INSPECTION
FUNCTION AND OPERATION PRICIPLE
Purge Control Solenoid Valve (PCSV) is installed on the surge tank and controls the passage between the canister
and the intake manifold. It is a solenoid valve and is open when the PCM grounds the valve control line. When the
passage is open (PCSV ON), fuel vapors stored in the canister is transferred to the intake manifold.

DESCRIPTION
The CVVT (Continuously Variable Valve Timing) which is installed on the exhaust camshaft controls intake valve open
and close timing in order to improve engine performance.
The intake valve timing is optimized by CVVT system depending on engine rpm.
This CVVT system improves fuel efficiency and reduces NOx emissions at all levels of engine speed, vehicle speed,
and engine load by EGR effect because of valve over - lap optimization.
The CVVT changes the phase of the intake camshaft via oil pressure.
It changes the intake valve timing continuously.
OPERATION
The CVVT system makes continuous intake valve timing changes based on operating conditions.
Intake valve timing is optimized to allow the engine to produce maximum power.
Cam angle is advanced to obtain the EGR effect and reduce pumping loss. The intake valve is closed quickly to
reduce the entry of the air/fuel mixture into the intake port and improve the changing effect.
Reduces the cam advance at idle, stabilizes combustion, and reduces engine speed.
If a malfunction occurs, the CVVT system control is disabled and the valve timing is fixed at the fully retarded position.

1.The above figure shows the relative operation structures of the housing vane to the rotor vane.
2. If the CVVT is held a certain control angle, to hold this state, oil is replenished as much as oil leaks from the oil
pump.
The OCV (Oil - flow Control Valve) spool location at this time is as follows.
Oil pump → Advance oil chamber (Little by little open the inflow side to the advance oil chamber) → Almost close the
drain side
Be sure there might be a difference in the position according to the engine running state (rpm, oil temperature, and oil
pressure).
