Upper Diagnost
ic Limit
This is the minimum throttle percentage that is
detected by the
ECM in normal operation when the
pedal is in the maximum position. A value above this
limit will generate an open circuit diagnostic code.
The range of th
is diagnostic detection area is from
the programmed value of the upper position limit to
100 percent.
Table 9
Range Default
0 to 100 percent 0 percent
Lower Position Limit
This is the minimum throttle percentage that will
be interpreted by the ECM as zero throttle. This
parameterisusedwiththevalueofinitiallower
position limit to make an allowance for manufacturing
tolerances between different speed demand input
devices.
Table 10
Range Default
0 to 100 percent 0 percent
Upper Position Limit
This is the maximum throttle percentage that will be
interpreted by the ECM as full throttle. This parameter
is used with the value of the initial upper position limit
to make an allowance for manufacturing tolerances
between different speed demand input devices.

Range
Default
0 to 100 percent 0 percent
Initial Lower Position Limit
This is the maximum throttle percentage that will
be interpreted by the ECM as zero throttle. This
parameter is used with the value of the lower
position limit to make an allowance for manufacturing
tolerances between different speed demand input
devices.

Initial Upper P
osition Limit
This is the minimum throttle percentage that will
be in terpreted
by the ECM as zero throttle. This
parameter is used with the value of the upper
position limit to make an allowance for manufacturing
tolerances be
tween different speed demand input
devices.

Range
Default
0 to 100 percent 0 percent
Lower Dead Zone
This is a throttle range above the initial lower position
limit before the engine will increase in rpm.
Table 14
Range Default
0 to 100 percent 0 percent
Upper Dead Zone
This is a throttle range that is below the initial upper
position limit that does not allow the engine speed
to increase.

Range Default
0 to 100 percent 0 percent
