2.

3.
Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404A), gray pin probes and patch cords.
Diagnostic Tips
The DVOM reads throttle position in volts. Voltage should
increase at a steady rate as the throttle is moved from idle to
wide open. A short to ground or open on the GY/V or R/W
wires also will result in a DTC P0122. A short to ground or
open on the R/W wire (+5v REF) sets multiple codes as
described below.
NOTE
The MAP, TP and VSS sensors are connected to the same
reference line (+5V Vref). If the reference line goes to ground
or open, multiple codes will be set (DTC P0107, P0108,
P0122, P0123, P0501, P0502). Start with the trouble code
having the lowest ranking value.

Fuel Injectors
The fuel injectors are solenoids that allow pressurized fuel
into the intake tract. The injectors are timed to the engine
cycle and triggered sequentially. The power for the injectors
comes from the system relay. The system relay also provides
power for the fuel pump and the ignition coil. The ECM pro-
vides the path to ground to trigger the injectors.

NOTE
(Part No. HD-34730-2C)

lems will cause 12 volt power to be lost to both injectors, igni-

Vehicle Speed Sensor
See Figure 5-56. The VSS is powered and monitored by the
ECM. The ECM processes the vehicle speed signal and
transmits this signal to the TSM/TSSM and speedometer
through serial data.
NOTE
When the vehicle speed is greater than 0, the closed loop idle
speed control is inhibited.
