Air-fuel ratio sensor 1
• Use Tool (A) to install the air-fuel ratio sensor 1 (if removed). CAUTION:
• Handle it carefully and avoid impacts.
• Before installing a new air-fu el ratio sensor 1, clean the
exhaust tube threads using suit able tool and approved anti-
seize lubricant.
• Do not over-tighten the air-fuel ratio sensor 1. Doing so may damage the air-fuel ratio senso r 1, resulting in the MIL com-
ing on.

12. Pull out the stopper pin (A), and then apply the tension to the
timing chain by rotating the crankshaft pulley clockwise slightly.
13. Pull out the stopper pin of chain tensioner.
14. Install front cover.
15. Return the camshaft sprocket (INT) in the most retarded position:
a. Remove the stopper pin (A) from the camshaft sprocket (INT).
b. Turn the crankshaft pulley (1) slowly clockwise (A) and return the camshaft sprocket (INT) to the most retarded angle position.
• When first turning the crankshaft, the camshaft sprocket (INT)
will turn. Once it is turned more, and the vane (camshaft) also
turns, then it has reached t he most retarded angle position.
• The most retarded angle position can be checked by seeing if the stopper pin groove (A) is shifted clockwise.
• After spinning the crankshaft slightly in the counterclockwise direction, you can check the lock pin has joined by seeing if
the vane (camshaft) and the sprocket move together.
16. Install the camshaft position sensor (PHASE) to the rear end of cylinder head. • Tighten bolts with it completely inserted.
17. Check and adjust valve clearance. Refer to EM-10, "
Inspection and Adjustment".
18. Installation of the remaining components is in the reverse order of removal.
