Oxygen Sensor Heater Monitor
Exhaust Gas Recirculation Monitor
Throttle Position Sensor Track Test
- 97 MY

This test
is
used
to
detect
any
problems with
the
throttle
potentiometer track which could cause faulty throttle
position signals
to
enter
the
PCM. Such signals would
result
in
incorrect calculation
of
engine power demand
and possibly create excessive fuelling and high emissions.
Selecting Throttle Checks from
the
Engine Diagnostics
screen will bring uptheThrottle Position Sensor Track Test

Follow the screen instructions
to
test the throttle position
sensor track. The throttle must be moved slowly from fu
I
ly
closed
to
fully open without hesitation.
Any
pause
in

throttle movement will
be
interpreted
as a
track fault.
If
a
fault
is
detected, repeat
the
test several times
to

elliminate hesitant throttle movement errors from actual
potentiometer faults.
If
a repeatable fault
is
detected,
the

potentiometer must
be
replaced.

Output State Control - 97 MY
This menu item provides a quick test of the basic electro­
mechanical components controlled by the PCM. These
tests should be performed in a key on engine off state.
The selections available are:
• Low Speed Cooling Fans
• High Speed Cooling Fans
• Set Electromechanical Outputs
Low and High Speed Fans
Selecting and confirming either the low or high speed
cooling fans will run the fans at the selected speed for 5
seconds to verify their operation.
Electromechanical Outputs
This selection will cause the following electromechanical
devices to operate for five seconds
Air Pump
Fuel Pumps
Canister Purge Valve
Idle Air Control Valve
Observing each device in turn as the PCM outputs are
turned 'On' will enable the technician to verify correct

operation.
