Downloaded from www.Manualslib.com manuals search engine GENERAL INFORMATION
Description
The Engine Control Module (ECM) consists of a microcomputer and connectors for signal input and output and for
power supply. The ECM controls the engine.
The following are the input and output components monitored by the ECM. The monitored functions include compo-
nents from the engine, ignition, transaxle, air conditioning, or any other ECM supported subsystem.
ECM Inputs
•Brake Switch Sensor
• Camshaft Position (CMP) Sensor
• Crankshaft Position (CKP) Sensor
• Engine Coolant Temperature (ECT) Sensor
• Air Flow Sensor
• Coolant Temperature Sensor (For Instrument Cluster)
• Throttle Position Sensor (Integral with Electronic Throttle Control Actuator)
• Power Steering Switch
• Knock Sensor
• Oxygen Sensor (Upstream & Downstream)
• Clutch Pedal Switch (Manual transmission only)
ECM Outputs
• Canister Control Valve
• Fuel Injectors
• Fuel Pump Relay
• Electronic Throttle Control Actuator
• Ignition Coil
• A/C Compressor
• Cooling Fan
• Oxygen Sensor heating coil (Upstream & Downstream)
Operation
The ECM monitors components and circuits and tests them in various ways depending on the hardware, function,
and type of signal. For example, analog inputs such as throttle position or engine coolant temperature are typically
checked for opens, shorts and out-of-range values. This type of monitoring is carried out continuously. Some digital
inputs like vehicle speed or crankshaft position rely on rationality checks - checking to see if the input value makes
sense at the current engine operating conditions. These types of tests may require monitoring several components
and can only be carried out under appropriate test conditions.
The ECM is a pre-programmed, microprocessor-based digital computer. It regulates ignition timing, air-fuel ratio,
emission control devices, charging system, certain transmission features, speed control, air conditioning compressor
clutch engagement and idle speed. The ECM can adapt its programming to meet changing operating conditions.

Coolant Temperature Sensor (For Instrument Cluster)
Description
The coolant temperature sensor (for instrument cluster) is located on the water outlet fitting. It is bimetallic strip struc-
ture.
Operation
The coolant temperature sensor (for instrument cluster) provides an input to the instrument cluster. With the coolant
temperature changes the bimetallic strip will curve complete the circuit and the temperature gauge will change.
Removal & Installation
1. Disconnect and isolate the negative battery cable.
2. Disconnect the coolant temperature sensor (for
instrument cluster) electrical connector.
3. Remove the coolant temperature sensor (1) (for instrument cluster).
(Tighten: Coolant temperature sensor (for instru-
ment cluster) to 14 N·m)

CAUTION:
Before removing the coolant temperature sensor (for instrument cluster), release the coolant pres-
sure and make sure the engine is cold.
Knock Sensor
Description
The knock sensor is attached to the cylinder block. The knock sensor is designed to detect engine vibration that is
caused by detonation.
Operation
When the knock sensor detects a knock in one of the cylinders, it sends an input signal to the ECM. In response, the
ECM retards ignition timing for all cylinders by a scheduled amount.
Knock sensors contain a piezoelectric material which constantly vibrates and sends an input voltage (signal) to the
ECM while the engine operates. As the intensity of the vibration increases, the knock sensor output voltage also
increases.
The voltage signal produced by the knock sensor increases with the amplitude of vibration. The ECM receives an
input knock sensor voltage signal. If the signal rises above a predetermined level, the ECM will store that value in
memory and retard ignition timing to reduce engine knock. If the knock sensor voltage exceeds a present value, the
ECM retards ignition timing for all cylinders. It is not a selective cylinder retard.
The ECM ignores knock sensor input signal during engine idle conditions. Once the engine speed exceeds a spec-
ified value, knock retard is allowed.
Removal & Installation
1. Disconnect and isolate the negative battery cable.
2. Disconnect the knock sensor electrical connector.
3. Remove the knock sensor retaining bolt (1) andremove the knock sensor.
(Tighten: Knock sensor retaining bolt to 20 N·m).
4. Installation is in the reverse order of removal.
Oxygen Sensor
Description
This vehicle is equipped with two oxygen sensors (upstream oxygen sensor & downstream oxygen sensor). The oxy-
gen sensors are located before and after the three way catalyst. The oxygen sensors continually monitor the oxygen
level in the exhaust gas. The sensor is made of ceramic zirconia. The zirconia generates voltage from approximately
1 volt in richer conditions to 0 volt in leaner conditions.
Operation
The O2 sensors produce voltages from 0 to 1 volt, depending upon the oxygen content of the exhaust gas. When a
large amount of oxygen is present (caused by a lean air/fuel mixture, can be caused by misfire and exhaust leaks),
the sensors produces a low voltage. When there is a lesser amount of oxygen present (caused by a rich air/fuel
mixture, can be caused by internal engine problems) it produces a higher voltage. By monitoring the oxygen content
and converting it to electrical voltage, the sensors act as a rich-lean switch.
