REMOVAL AND INSTALLATION <4G1>

caution

When the detonation sensor replacement is performed, idling speed may be unstable because the MPI engine learning is not completed. To make it stable, make the system learn the idling (Refer to GROUP 00, Precautions before Service - Learning Procedure for Idling in MPI Engine ).
Do not drop or hit the detonation sensor against other components. Internal damage may result, and the detonation sensor will need to be replaced.
