Caution
• When foreign material, such as 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.
• Do not forcefully pull the wiring harness of the CKP sensor. Doing so will break the harness.
1. Disconnect the negative battery cable.
2. Remove the crankshaft pulley. (See B2–9 TIMING BELT REMOVAL/INSTALLATION.)
3. Remove the lower timing belt cover. (See B2–9 TIMING BELT REMOVAL/INSTALLATION.)
4. Remove in the order indicated in the table.
5. Install in the reverse order of removal.
