DTC Troubleshooting
NOTE
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors re ferring to “Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.

Step Action YesNo
1 Is DTC P0010 detected together? Go to “DTC P0010: “A”
Camshaft Position
Actuator Circuit”.Go to Step 2.
2 Do you have SUZUKI scan tool? Go to Step 3.Go to Step 5.
3 Camshaft position control check
1) With ignition switch turned OFF, connect SUZUKI scan
tool to DLC.
2) Start engine and warm up to normal operating temperature.
3) Select menu to DATA LIST.
4) Check that “VVT GAP” displayed on SUZUKI scan tool is 0 – 5 °.
Is it OK? Go to Step 4.
Check valve timing
referring to “Timing

4 Camshaft position control check
1) Drive vehicle under following conditions.
• Vehicle speed at 80 km/h (50 mile/h).
• Gear position at 5th or D range.
2) Check that “VVT GAP” displayed on SUZUKI scan tool is 0 – 5 °.
Is it OK? Substitute a known-
good ECM and recheck.
Go to Step 5.
5 Oil control circuit visual inspection

2) Remove oil gallery pipe refe rring to “Timing Chain Cover
Removal and Installation in Section 1D”.
3) Check oil gallery pipe and o il control valve for clog or
sludge.
Are they in good condition? Go to Step 7.
Clean oil control valve
and oil gallery pipe.
Replace oil control valve
if a problem is not
solved after cleaning oil
control valve and oil
gallery pipe.
7 Oil control valve electrical circuit check
1) Check that oil control valve circuit is in good condition
referring to “DTC P0010: “A” Camshaft Position Actuator
Circuit”.
Is circuit in good condition? Go to Step 8.
Repair circuit.
8 Oil control valve check

6) Connect special tool (Vacuum gauge) to PCV hose (1).
Special tool
(A): 09915–67311
7) Blind PCV valve (2) using tape (3) or the like.
8) Install air cleaner assembly and air suction hose referring to “Air Cleaner Components”.
9) Run engine at specified idle speed and read vacuum gauge. Vacuum should be within specification.
Vacuum specification (at sea level)
59 – 73 kPa (45 – 55 cmHg, 17.7 – 21.6 in.Hg) at
specified idle speed
10) Remove air cleaner assembly and air suction hose referring to “Air Cleaner Components”.
11) Disconnect special tool (vacuum gage) from PCV valve.
12) Detach blind cap from PCV valve, and connect PCV hose to PCV valve.

3) Remove right side engine under cover, if necessary.
4) Using 17 mm wrench, turn crankshaft pulley (1) clockwise until cam lobes (2) become perpendicular
to shim faces (3) at valves “1” and “7” as shown in
the figure. 5) Check valve lashes with thickness gauge (4)
according to the following procedure.
a) Check valve lashes at valves “1” and “7”.
b) Turn camshafts by 90 ° (by turning crankshaft
with wrench).
c) Make sure that cam lobes are perpendicular to shim faces at valves to be checked (in this case,
“3” and “8”), if not, adjust it by turning crankshaft.

adjust it to specification by replacing shim.
Valve clearance specification
When cold (Coolant te mperature is 15 – 25 °C (59 –
77 °F)):
• Intake: 0.18 – 0.22 mm (0.007 – 0.009 in.)
• Exhaust: 0.28 – 0.32 mm (0.011 – 0.013 in.)

For example of intake side:
When thickness of removed shim is 2.40 mm (0.094
in.), and measured valve clearance is 0.45 mm
(0.018 in.).
A = 2.40 mm (0.094 in.) + 0.45 mm (0.018 in.) – 0.20
mm (0.008 in.) = 2.65 mm (0.104 in.)
Calculated thickness of new shim = 2.65 mm (0.104
in.)
6) Select new shim No. (1) with a thickness as close as possible to calculated value.
Available new shims No.
7) Install new shim facing shim No. side with tappet. 8) Lift valve by turning crankshaft counterclockwise (in
opposite direction against above Step 4)) and
remove special tool.
Special tool
(A): 09916–67020
(A): 09916–67021
9) Install camshaft housing (1) and tighten bolts to specified torque.
Tightening torque
Camshaft housing bolt (a ): 11 N·m (1.1 kgf-m,
8.0 lb-ft)
10) Check valve clearance again after adjusting it. 11) After checking and adjusting all valves.
12) Install cylinder head cover referring to “Cylinder Head Cover Removal and Installation”.
