Circuit Description
The ECM monitors the crankshaft and camshaft positions to detect if the engine is misfiring. The ECM looks for a quick
drop in crankshaft speed. Misfire multiple cylinder is monitored by engine roughness measuring. The actual roughness
value is compared with the actual (emission and catalyst damage) threshold.

Circuit Description
The ECM supplies a 5 volt reference signal and a ground to the TP sensor. The TP sensor sends a voltage signal back
to the ECM relative to the throttle plate opening. The voltage signalwill vary from approximately 0.3 ~ 0.9 volts at
closed throttle, to over 4.0 ~ 4.6 volts at Wide Open Throttle (WOT).
The TP sensors serve for engine load control according to the drive pedal command. Load adjustments independent of
the drive pedal command can be implemented; such functions are, for instance, idle control, speed control, drive slip
control, load shock damping, and similar functions.
When the actuator current fails, the throttle valve is returned to emergency operating position by a spring. The throttle
valve position, thereby the actuator drive position checkback is provided by two potentiometers. The motor positions
the throttle valve against the return spring force. Motor and return spring are two separate energy sources. Each of
them is able to position the throttle valve in emergency position alone. Throttle valve position checkback and monitor-
ing is provided by two actual value potentiometers connected to the engine control electronics.

Circuit Description
In order to control emissions, a catalytic converter is used to covert harmful emissions into harmless water vapor and
carbon dioxide. The ECM has the ability to monitor this process by using a oxygen sensor. The oxygen sensor pro-
duces and output signal which indicates the storage capacity of the catalyst. This in turn indicates the catalyst’s ability
to convert exhaust emission effectively. If the oxygen sensor pigtail wiring, connector, or terminal is damaged. Do not
attempt to repair the wiring, connector, or terminals. In order for the sensor to function properly, it must have a clean air
reference provided to it. This clean air reference is obtained by way of the oxygen sensor wire(s). Any attempt to repair
the wires, connector, or terminal and degrade the oxygen sensor performance.

Circuit Description
The provision for communicating with the ECM is the Data Link Connector (DLC). It is located in the instrument panel
fuse block. The DLC is used to connect the scan tool. Battery power and ground is supplied for the scan tool through
the DLC. CAN line is used to communicate with the other module such as the Transmission Control Module (TCM) and
Transfer Case Control Unit (TCCU).
Keyword 2000 Serial Data Communications
Each bit of information can have one of two lengths: long or short. This allows vehicle wiring to be reduced by transmit-
ting and receiving multiple signals over a singles wire. The message carried on KWP 2000 data streams are also priori-
tized. If two messages attempt to establish communications on the data line at the same time, only the message with
higher prioritywill must wait.
