SECONDARY TIMING CHAIN
4. Remove front chain case.
●Loosen fixing bolts in the reverse order of that shown in the
figure and remove them.
●Remove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:
●While front chain case is removed, cover openings to
prevent entry of foreign material into engine.
●Do not remove two mass dampers on the back of
cover.
5. Set the No. 1 piston to TDC on its compression stroke.
●Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.
●No position indicator is provided on the crankshaft pul-
ley.
●When installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
supply pump sprocket may not be easy to see.
6. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with a
push pin.
b. Using a hexagon-head wrench [face to face: 5 mm, (0.20 in)
SST], remove bolts to remove chain tensioner.

1. Perform EC-39, "
Accelerator Pedal Released Position Learning" .
2. Perform EC-39, "
Throttle Valve Closed Position Learning" .
3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic “PREPARATION” (previously mentioned) are in good order.
5. Turn ignition switch “OFF” and wait at least 10 seconds.
6. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
7. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MI stops
blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the MI goes off.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the
specifications.
13. If idle speed and ignition timing are not within the specification, “Idle Air Volume Learning” will not be car-
ried out successfully. In this case, find the cause of the incident by referring to the “DIAGNOSTIC PROCE-
DURE” below.
DIAGNOSTIC PROCEDURE
If idle air volume learning cannot be performed successfully, proceed as follows:
1.Check that throttle valve is fully closed.
2.Check PCV valve operation.
3.Check that downstream of throttle valve is free from air leakage.
4.When the above three items check out OK, engine component parts and their installation condi-
tion are questionable. Check and eliminate the cause of the incident.
