WARNING: This page is about a different variant/trim than selected.

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.
Do not assemble the CKP sensor or change the installation position using any method other than the following. Otherwise, it could negatively affect engine controls, such as the ignition timing and fuel injection.

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) (See DRIVE SHAFT REMOVAL/INSTALLATION .)
3. Remove the cylinder block lower blind plug and install the SST
