3. INSPECT FLOW CONTROL VALVE ASSEMBLY
(a) Coat the flow control valve assembly with power
steering fluid and check that it falls smoothly into the
flow control valve due to its own weight.
If the control valve does not fall into the hole
smoothly, replace the vane pump assembly.
(b) Check the flow control valve assembly for leaks.
Close one of the holes and apply compressed air,
392 to 490 kPa (4 to 5 kgf/cm
2, 57 to 71 psi), into
the opposite side hole, and confirm that air does not
come out from the holes in the ends of the flow
control valve assembly.
If air leaks, replace the vane pump assembly.
4. INSPECT FLOW CONTROL VALVE COMPRESSION
SPRING
(a) Using vernier calipers, measure the free length of
the flow control valve compression spring.
Minimum free length:
29.2 mm (1.150 in.)
If the length is less than the minimum, replace the
vane pump assembly.
5. INSPECT PRESSURE PORT UNION
If the union seat in the pressure port union is severely
damaged, replace the vane pump assembly.
6. INSPECT TOTAL PRELOAD
(a) Check that the pump rotates smoothly without
abnormal noise.
(b) Temporarily install the service bolt.
Recommended service bolt:
Thread diameter:
10 mm (0.39 in.)
Thread pitch:
1.25 mm (0.0492 in.)
Bolt length:
50 mm (1.97 in.)
(c) Using a torque wrench, check the pump rotating
torque.
Rotating torque:
0.27 N*m (2.8 kgf*cm, 2.4 in.*lbf) or less
If the rotating torque is not as specified, check the
vane pump housing oil seal.

BASIC INSPECTION
When a malfunction is not confirmed by the DTC check,
troubleshooting should be carried out in all circuits
considered to be possible causes of the problem. In many
cases, by carrying out the basic engine check shown in the
following flowchart, the location of the problem can be found
quickly and efficiently. Therefore, using this check is essential
when engine troubleshooting.
NOTICE:
Carry out this check with the engine stopped and ignition
switch off.

INSPECTION PROCEDURE
HINT:
• If DTC P0010 is displayed, check the intake camshaft circuit for the right bank VVT system.
• Bank 1 refers to the bank that includes cylinder No. 1.
• If DTC P0020 is displayed, check the intake camshaft circuit for the left bank VVT system.
• Bank 2 refers to the bank that does not include cylinder No. 1.
• Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame
data can be helpful in determining whether the vehicle was running or stopped, whether the engine
was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the
time of a malfunction.
(a) Connect the intelligent tester to the DLC3.
(b) Start the engine and turn the tester on.
(c) Warm up the engine.
(d) On the tester, enter the following menus: DIAGNOSIS /
ENHANCED OBD II / ACTIVE TEST / VVT CTRL B1 or
VVT CTRL B2.
(e) Check the engine speed while operating the Oil Control
Valve (OCV) using the tester.

HINT:
If DTC P0011, P0012, P0021 or P0022 is present, check the VVT (Variable Valve Timing) system.
DESCRIPTION
Refer to DTC P0010 (See page ES-75).
MONITOR DESCRIPTION
The ECM optimizes the intake valve timing using the VVT (Variable Valve Timing) system to control the
intake camshaft. The VVT system includes the ECM, the Oil Control Valve (OCV) and the VVT controller.
The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil
pressure applied to the VVT controller. The VVT controller can advance or retard the intake camshaft.
If the difference between the target and actual intake valve timings is large, and changes in actual intake
valve timing are small, the ECM interprets this as the VVT controller stuck malfunction and sets a DTC.
Example:
A DTC will be set when the following conditions 1), 2) and 3) are met:
1) The difference between the target and actual intake valve timings is more than 5
CA (Crankshaft
Angle) and the condition continues for more than 4.5 seconds.
2) It takes 5 seconds or more to change the valve timing by 5
CA.
