Leaking injectors will cause fuel imbalance and poor idle

See Figure 6-21. The ECM controls engine idle speed by

quality due to different air/fuel ratios in each cylinder. To

moving the IAC to open or close a passage around the throttle

plates. It does this by sending voltage pulses to the proper

filter. Then, with the throttle wide open, turn IGN ON for 2

Zero steps represents a fully extended pintle. A zero

reading indicates an abnormal condition in which the pintle

has been fully extended and has consequently closed the

passage around throttle plate.

Each time the ignition is turned OFF,

the ECM resets the IAC

by sending enough pulses to extend

the pintle and effectively

close the throttle body. The fully extended value is the ECM

reference point. A given number of steps are then calculated

by the ECM for use in setting the proper idle speed and IAC

position for the next start event.

NOTE

Idle speed is controlled by the ECM and cannot be adjusted.

DESCRIPTION AND OPERATION

ed03052

See Figure 6-27 and Figure 6-28. With IGN ON and the engine

stop switch at RUN, the ECM will energize the system relay to

complete the circuit to the in-tank fuel pump, ignition coils and

fuel injectors. They will remain powered as long as the engine

is cranking or running, and the ECM is receiving ignition refer-

ence pulses from the CKP sensor. If there are no reference

pulses, the ECM will de-energize the system relay within 2

seconds after ignition is ON or engine has stalled, or immedi-

ately after the ignition is shut OFF.

6.17

DESCRIPTION AND OPERATION

ed02859

Ignition coil DTCs will set if the ignition coil primary voltage is

out of range. This could occur if there is an open coil or loss

of power to the coil. If front and rear DTCs are set simultan-

eously, it is likely a coil power failure or a coil failure.

The coil receives power from the system relay at the same

time that the fuel pump and injectors are activated. The system

relay is active for the first 2 seconds after the ignition switch is

turned ON and then shuts off until rpm is detected from the

CKP sensor, at which time system relay is reactivated. The

ECM is responsible for turning on the system relay by providing

the ground to activate the relay, which in turn powers the coil.

DESCRIPTION AND OPERATION

NOTE

See Figure 6-33. The Jiffy Stand Sensor (JSS) uses a Hall-

The ECM supplies 5V reference voltage to the VSS, TPS and

effect sensor to monitor jiffy stand position. When the jiffy stand

tab mounted to the jiffy stand. The metal tab is moved away

from the sensor as the jiffy stand is extended. When the jiffy

ed01247

stand is extended the engine will only start and run if the TSM,

TSSM or HFSM determines the transmission is in neutral.

Otherwise the engine will stall as the clutch is released. This

is done by monitoring the neutral switch input to the TSM,

TSSM or HFSM and communicating that input over the serial

data circuit to the ECM.

The JSS is powered and monitored by the ECM. The ECM

supplies the 5V reference to the JSS. The JSS sends a signal

back to the ECM. This signal is used by the ECM to determine

when the jiffy stand is retracted or extended. The JSS is

grounded through the ECM.

The JSS also has a Fail Enable Mode. This mode allows the

engine to start and run if the system recognizes a problem with

the JSS circuit. When a problem exists or if the transmission

is put in gear with the jiffy stand extended, the odometer will
