Crankshaft Position (CKP) Sensor Removal/Installation: Installation

CAUTION:

When foreign material, such as an iron chips, gets on the CKP sensor, it can cause abnormal output from the sensor because of flux turbulence and adversely affect engine control. Be sure there is no foreign material on the CKP sensor when replacing.

Perform the following procedure so that piston No. 1 is at the top dead center.
1. Remove the drive shaft (RH). (See DRIVE SHAFT REMOVAL/INSTALLATION [L3] .)
2. Remove the cylinder block lower blind plug and install the SST.
3. Turn the crankshaft pulley to the clockwise until it stops.

2. Using a straight edge, draw a straight line directly in the center of the ninth tooth of the crankshaft pulley pulse wheel (counting counterclockwise from the empty space).
CAUTION:
- If the line is not accurately drawn, ignition timing, fuel injection and other engine control systems will be adversely effected. Draw the straight line carefully using a straight edge.
