KNOCK SENSOR (KS) REMOVAL/INSTALLATION [L3 WITH TC]

CAUTION

Be careful not to impact the sensor. Verify that there is no debris between the sensor and the cylinder block before installing.

Scheme 172

Remove the intake manifold. (See «INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3 WITH TC]»(ref-244582-S40996001322006092500000) ).
Remove the KS attachment bolt to remove the KS.
Install in the reverse order of removal. Tightening torque 16-24 N.m {1.7-2.4 kgf.m, 12-17 ft.lbf}

Removal

Perform the following procedure to allow for enough working space. Remove the Front wheel (RH). Remove the splash shield.
Disconnect the CKP sensor connector.
Remove the installation bolts to remove the CKP sensor.

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.

Scheme 173

Scheme 174

Perform the following procedure so that piston No.1 is at the top dead center. Remove the drive shaft (RH). (See «FRONT DRIVE SHAFT REMOVAL/INSTALLATION [L3, L3 WITH TC]»(ref-244605-S25656314442006092500000) ). Remove the cylinder block lower blind plug and install the SST . Turn the crankshaft pulley to the clockwise until it stops.
Using a straight edge, draw a straight line directly in the center of the twentieth 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.
Align the center line of the crankshaft position sensor and the line drawn in Step 2 , then install the sensor.
Install the CKP sensor fitting bolts. Tightening torque 5.5-7.5 N.m {56-76 kgf.cm, 49-66 in.lbf}
Remove the SST then install the cylinder block lower blind plug. Tightening torque 18-22 N.m {1.9-2.2 kgf.m, 14-16 ft.lbf}
Install the front drive shaft (RH). (See «FRONT DRIVE SHAFT REMOVAL/INSTALLATION [L3, L3 WITH TC]»(ref-244605-S25656314442006092500000) ).
