Attach Electronic Control Module (ECM) to Breakout Box (B-48115). Plug
DVOM (Part No. HD-39978) into Pin 4 (+) and Pin 27 (-) of Breakout Box
connector [11] (Gray). With Ignition Switch ON, gradually open throttle while
observing voltage.
Does voltage steadily increase with no spikes or low voltages observed from
0.3-1.5 volts at idle (closed throttle) to 3.9-4.9 volts at wide open throttle?
Check engine lamp
continuously ON and
DTC P0122 (11), P0123
(11) only set?
Was voltage greater
than 4.9 volts?
Replace ECM.
Check for intermittents. See
2.7 WIGGLE TEST.
Intermittents present?
Disconnect TPS sensor connector
[88] and ECM connector [11]
(Gray). Measure voltage at Pin 4 (+)
and Pin 19 (-).
Does voltage measure 5.0 volts?
To identify source of
intermittents, start at box
marked by Bold Asterisk
on right side of flow
chart. Follow steps while
wiggling harness and
monitoring DVOM.
Replace TPS. (See
THROTTLE POSITION
SENSOR in Buell Service
Manual.) Clear codes
and road test.
Did check engine lamp
come on and set DTC
P0122 (11), P0123 (11)?
Reconnect TPS connector
[88]. Measure TPS voltage
at wide open throttle.
Is voltage greater than 5.0
volts?
Locate and repair
short between (V/Y)
wire and battery
voltage.
Install original TPS
and replace ECM. Road
test again to verify.
System
now OK.
Locate and repair short
between (R/W) wire
and battery voltage.
Locate and repair
short between (V/Y)
wire and (R/W) wire.
Go to Throttle Position
Sensor Test DTC P0122
(11); P0123 (11) (Part 2 of 2).
At some point in the flow chart you
may be instructed to jump directly
to a the box with the bold asterisk.
Disregard the asterisk (but not the
instruction box) if your normal
progression through the chart brings
you to this location.
NOTES:
Clear DTCs and confirm proper operation with no
check engine lamp. Codes can be cleared using
DIGITAL TECHNICIAN (Part No. HD-44750).
After replacing ECM or TPS, TPS zero set procedure
must be performed. Refer to THROTTLE POSITION
SENSOR in the appropriate Buell Service Manual.
