TIMING CHAIN
a. Install the crankshaft sprocket (1), the oil pump drive chain (2),
and the oil pump sprocket (3) at the same time.
• Install the crankshaft sprocket so that its invalid gear area (A)is toward the back of the engine.
• Install the oil pump sprocket so that its protrusion faces the front of engine.
NOTE:
There is no matching mark in the oil pump drive related parts.
b. Hold the top of the oil pump shaft using the socket (size: E8), and then tighten the oil pump sprocket nut.
c. Install oil pump drive chain tensioner (1). • Insert the body into the shaft (B) while inserting the spring intothe attaching hole (A) of cylinder block front surface.
• Check that the tension is applied to the oil pump drive chain
after installing.
2. Install timing chain:
• Install by aligning matching marks on each sprocket and tim-ing chain.
• If these matching marks are not aligned, rotate the camshaft
slightly to correct the position.
CAUTION:
• After the matching marks are aligned, keep them aligned by holding them.
• To avoid skipped teeth, do not rotate crankshaft and cam- shaft until front cover is installed.

6.PERFORM IDLE AIR VOLUME LEARNING
Perform EC-130, "
Description".
Is Idle Air Volume Learning carried out successfully?
YES >> GO TO 7.
NO >> Follow the instruction of IDLE AIR VOLUME LEARNING. Then GO TO 4.
7.CHECK TARGET IDLE SPEED AGAIN
1. Start engine and warm it up to normal operating temperature.
2. Check idle speed. For procedure, refer to EC-471, "
Inspection".
For specification, refer to EC-478, "

DTC Logic".
• Check crankshaft position sensor (POS) and circuit. Refer to EC-278, "
DTC Logic".
Is the inspection result normal?
YES >> GO TO 9.
NO >> Repair or replace. Then GO TO 4.
9.CHECK ECM FUNCTION
1. Substitute another known-good ECM to check ECM function. (ECM may be the cause of an incident, but this is a rare case.)
2. Perform initialization and registration of all NATS ignition key IDs. Refer to SEC-49, "
ECM : Descrip-
tion"(with intelligent key) or SEC-142, "ECM RE-COMMUNICATING FUNCTION : Description"(without
