•  If the ion sensor detects pre-ignition, the fuel amount is increased and the intake camshaft is retarded to prevent pre-ignition.

•  The ion sensor cannot be replaced as a single unit. If replacement is required, replace the appropriate ignition coil (with built-in ion sensor).To examine, perform the inspection following the service manual (DTC inspection, damage to ignition coil/ion sensor, visual inspection for connector corrosion, damage).
