Purpose/Function
Detects ion generation in the combustion chamber for detecting pre-ignition.
Detects ions which occur due to fuel combustion as current by applying bias voltage to the spark plug, which is amplified in the ignition coil internal circuit and input to the PCM.
Construction
Built into the ignition coil.
Operation
Accumulates the secondary current of the ignition coil in bias condenser (1) and detects ion current (2) by applying the bias voltage to the spark plug.
Pulls in current (4) increased by current amplification circuit (3) to the ignition coil from the PCM.
The PCM measures/converts the current sent to the ignition coil and monitors.
Ion generation mechanism
Ions are generated based on: fuel combustion = chemical reaction / disassociation. The generated negative ions move to the center electrode of the spark plug to which bias voltage is applied, positive ions move to the grounded engine wall surface, and then current flows from the spark plug to the ignition coil.

Rear Drive Shaft Inspection
1. Inspect each connecting part for looseness.
Tighten or replace parts if necessary.
2. Inspect the dust boot on the drive shaft for cracks, damage, leaking grease,
and looseness in the boot band.
3. Inspect the drive shaft for bends, cracks, and wear in the joints or splines. ...
