2. DESCRIPTION AND OPERATION
1) Cleanliness And Care
An automobile engine is a combination of many machined, honed, polished and lapped
surfaces with tolerances that are measured in the ten-thousanths of an inch. When any internal
engine parts are serviced, care and cleanliness are important. A liberal coating of enigne oil
should be applied to friction areas during assembly, to protect and lubricate the surfaces on
initial operation.
Proper cleaning and protection of machined surfaces and friction areas is part of the repai
r
procedure. This is considered standard shop practice even if not specifically stated.
Whenever valve train components are removed for service, they should be kept in order.
They should be installed in the same locations, and with the same mating surfaces, as when
they were removed. Battery cables should be disconnected before any major work is performed
on the engine. Failure to disconnect cables may result in damage to wire harness or othe
r
electrical parts.
2) On-Engine Service
Disconnect the negative battery cable before removing or installing any electrical unit, or
when a tool or equipment could easily come in contact with exposed electrical terminals.
Disconnecting this cable will help prevent personal injury and damage to the vehicle.
The ignition must also be in LOCK unless otherwise noted.
Notice Any time the air cleaner is removed, the intake opening -
Any time the air cleaner is removed, the intake opening should be covered. This will
protect against accidental entrance of foreign material, which could follow the intake
passage into the cylinder and cause extensive damage when the engine is started.g -

3. IGNITION SYSTEM OPERATION
This ignition system does not use a conventional distributor and coil. It uses a crankshaft
position sensor input to the Engine Control Module (ECM).
The ECM then determines Electronic Spark Timing (EST) and triggers the electronic ignition
system ignition coil.
This type of distributorless ignition system uses a “waste spark” method of spark
distribution. Each cylinder is paired with the cylinder that is opposite it (2.3L DOHC: 2 - 3 or 1 -
4, 3.2L DOHC: 1 - 6 or 2 - 5 or 3 - 4).
The spark occurs simultaneously in the cylinder coming up on the compression stroke and in
the cylinder coming up on the exhaust stroke.
The cylinder on the exhaust stroke requires very little of the available energy to fire the spark
plug.
The remaining energy is available to the spark plug in the cylinder on the compression stroke.
These systems use the EST signal from the ECM to control the EST.
The ECM uses the following information: Engine load (mass air flow sensor, manifold ai
r
pressure sensor).
Engine coolant temperature.
Intake air temperature.
Crankshaft position.
Engine speed (rpm).
1) Electronic Ignition System Ignition Coil
The Electronic Ignition (EI) system ignition coil is located on the cylinder head cover.
The double ended coils re ceive the signal for the ECM which controls the spark advance.
Each EI system ignition coil provides the high voltage to two spark plugs simultaneously;
3.2L DOHC
T1/1: cylinder 2 and 5
T1/2: cylinder 3 and 4
T1/3: cylinder 1 and 6
The EI system ignition coil is not serviceable and must be replaced as an assembly.
