Crankshaft Position (CKP) Sensor Removal/Installation: Removal: Installation

CAUTION:

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

Perform the following procedure so that cylinder No. 1 is at TDC.
1. Remove the wheel and tire (front right side).
2. Disconnect the drive shaft (RH) from joint shaft, set the drive shaft (RH) out of the way. (MTX)
3. Remove the cylinder block lower blind plug and install the SST.
4. Rotate the crankshaft pulley clockwise until the crank weight contacts the SST so that cylinder No. 1 is at TDC.
