DESCRITION
Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data
for the engine operating conditions are preprogrammed in the memory of the ECM (Engine Control Module).
The engine operating conditions (speed, load, warm- up condition, etc.) are detected by the various sensors. Based on
these sensor signals and the ignition timing data, signals to interrupt the primary current are sent to the ECM. The
ignition coil is activated, and timing is controlled.

DESCRIPTION
Modifications to the combustion chamber, intake manifold, camshaft and ignition system form the basic control system.
These items have been integrated into a highly effective system which controls exhaust emissions while maintaining
good driveability and fuel economy.
AIR/FUEL MIXTURE CONTROL SYSTEM [MULTIPORT FUEL INJECTION (MFI) SYSTEM]
This in turn allows the engine to produce exhaust gases of the proper composition to permit the use of a three way
catalyst. The three way catalyst is designed to convert the three pollutants (1) hydrocarbons (HC), (2) carbon
monoxide (CO), and (3) oxides of nitrogen (NOx) into harmless substances. There are two operating modes in the MFI
system.
1. Open Loop air/fuel ratio is controlled by information programmed into the ECM.
2. Closed Loop air/fuel ratio is adjusted by the ECM based on information supplied by the oxygen sensor.

during testing. An example would be if a problem appears only when the vehicle is cold but has not appeared when
warm. In this case, the technician should thoroughly make out a "CUSTOMER PROBLEM ANALYSIS SHEET" and
recreate (simulate) the environment and condition which occurred when the vehicle was having the issue.1. Clear Diagnostic Trouble Code (DTC).
2. Inspect connector connection, and check terminal for poor connections, loose wires, bent, broken or corroded pins,
and then verify that the connectors are always securely fastened.
3.Slightly shake the connector and wiring harness vertically and horizontally.
4. Repair or replace the component that has a problem.
5. Verify that the problem has disappeared with the road test.
● SIMULATING VIBRATION
a. Sensors and Actuators
: Slightly vibrate sensors, actuators or relays with finger.
Strong vibration may break sensors, actuators or relays
b. Connectors and Harness
: Lightly shake the connector and wiring harness vertically and then horizontally.
● SIMULATING HEAT
a. Heat components suspected of causing the malfunction with a hair dryer or other heat source.
a.DO NOT heat components to the point where they may be damaged.
b. DO NOT heat the ECM directly.
● SIMULATING WATER SPRINKLING
a. Sprinkle water onto vehicle to simulate a rainy day or a high humidity condition.
DO NOT sprinkle water directly into the engine compartment or electronic components.
● SIMULATING ELECTRICAL LOAD
a. Turn on all electrical systems to simulate excessive electrical loads (Radios, fans, lights, rear window defogger,
etc.).
