Description and operation

Description

An ignition coil is an induction coil in an engine's ignition system which transforms the battery's low voltage to the high voltage needed to create an electric spark in the spark plugs to ignite the fuel. Coils have an internal resistor while others rely on a resistor wire or an external resistor to limit the current flowing into the coil from the battery 12 V supply.

Repair procedures

Removal

1.	Disconnect the battery nagative terminal.

2.	Remove the engine cover.

Remove the ignition coil (A) after loosening the mounting bolts.

Ignition coil mounting bolt:

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 Ib·ft)

•	When removing the ignition coil connector, pull the lock pin (A) and push the clip (B).

Installation

1.	Install in the reverse order of removal.

Inspection

Measure the primary coil resistance between terminal 1 and 2.

Standard value: 0.74Ω ± 10% [20°C (68°F)]

❮Ignition System

Description and operation Description Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data for the engine operating conditions are pre-pro grammed in the memory of the ECM (Engine Control Module).
