SENSORS AND DRIVERS

DESCRIPTION AND OPERATION

Sensors and drivers play an important part in the ECM's ability
to provide the proper operational parameters for engine effi-
ciency, emissions control and fuel economy. When a failure
occurs, a DTC is generated by, and stored in, the ECM. These
codes help the technician diagnose engine trouble to the proper
sensor or driver. See

2.1 INITIAL DIAGNOSTICS

SENSORS

TOOL NAME

PART NUMBER

DIGITAL TECHNICIAN II

HD-48650

Not all sensor problems cause an engine shutdown, but sensor
failure can seriously degrade overall engine performance. A
notable exception is the CKP sensor, which if faulty, completely
disables engine operation. The following are brief explanations
of sensor types and their functions within the EFI system.

Crank Position (CKP) Sensor

The CKP sensor, located on the left front of the lower crankcase
half, is a variable reluctance sensor that generates AC voltage
as the teeth on the flywheel pass by the sensor. The signal is
routed to the ECM where it is used to determine crankshaft
position, engine speed (rpm) and engine phase (TDC compres-
sion). Without the presence of the CKP signal, the ECM will
not allow the ignition and fuel injection drivers to operate, and
thus the engine will not run. The ECM uses crankshaft com-
pression slow down events to determine engine phase.
Therefore, the spark plugs must be installed when checking
for spark.

Twist Grip Sensor (TGS)

The TGS, mounted on the right hand side of the handlebar,
houses two internal (opposing) Hall-effect sensors for operator
control of the engine's throttle. The opposing operation of the
sensors ensures that repositioning of the throttle twist grip,
forward and/or back, is accurately reported to the ECM. As the
throttle is operated, position changes are reported to the ECM
that controls the corresponding movement of the throttle plate
by the TCA.

Twist Control Actuator (TCA)

The TCA, mounted to the intake manifold, operates the throttle
plate internal to the induction module on the engine. Two cor-
responding TP sensors provide input to the ECM, so the ECM
may verify that plate position corresponds to TGS input (rider
desired position of the plate) and to adjust the position of the
throttle plate, accordingly.

Jiffy Stand Sensor (JSS): HDI

The JSS uses a Hall-effect device to monitor jiffy stand position.
When the jiffy stand is fully retracted, the sensor picks up the
presence of a metal tab mounted to the jiffy stand. When
extended, the engine only starts and runs if the ECM receives
a signal from the neutral switch indicating the transmission is
in neutral, or a signal from the clutch switch indicating the clutch
is engaged. Otherwise, the engine stalls as the clutch is
released with the transmission in gear.

Bank Angle Sensor (BAS)

The BAS is within the TSM/TSSM/HFSM.

The

TSM/TSSM/HFSM will shut the engine down if the vehicle is
tipped over. Once the sensor is tripped, the motorcycle must
be righted, the ignition turned off and then on again before the
engine can be restarted. This is communicated across the
serial data circuit.

Clutch Switch

The TSM/TSSM/HFSM provides voltage to the clutch switch,
which is open when the clutch is disengaged (released). With
the clutch engaged (pulled in), the switch closes, allowing
current flow to ground. The ECM will not allow the engine to
start unless the transmission is in neutral or the clutch is
engaged.

Neutral Switch

The instrument fuse provides voltage to the neutral switch,
which is open when the transmission is in gear. With the
transmission in neutral, the switch is closed, allowing current
flow to ground. The TSM/TSSM/HFSM will not allow the engine
to start unless the transmission is in neutral or the clutch is
engaged.

Engine Temperature (ET) Sensor

The ET sensor is a thermistor device, which means that at a
specific temperature it has a specific resistance across its ter-
minals. As this resistance varies, so does the voltage.

•

At high temperatures, the resistance of the sensor is very
low, which effectively lowers the signal voltage on ECM
[78] terminal 51.

•

At low temperatures, the resistance is very high, allowing
the voltage to rise close to 5V. The ECM monitors this
voltage to compensate for various operating conditions.

Temperature Manifold Absolute Pressure
(TMAP) Sensor

The TMAP sensor combines the MAP and IAT in a single
component. Each functions as described in the paragraphs
following, and are tested as separate units.

Manifold Absolute Pressure (MAP) Sensor

The MAP sensor is supplied 5V from the ECM and sends a
signal back to ECM. This signal varies in accordance with
engine vacuum, intake air temperature and atmospheric baro-
metric pressure. The MAP sensor monitors the intake manifold
pressure (vacuum) and sends the information to the ECM. The
ECM then adjusts the spark and fuel timing advance curves
for optimum performance. The output of the sensor can also
be used to determine if the engine is rotating when a fault with
the CKP sensor is present.

Intake Air Temperature (IAT) Sensor

The IAT sensor is a thermistor device. As such, it will have a
specific resistance across its terminals at a specific temper-

6-6 2011 Touring Diagnostics: Engine Management

ature. As the temperature varies, the thermistor resistance
varies, and so does the voltage on ECM [78] terminal 49.

•

At high temperatures, the resistance of the sensor is very
low, which effectively lowers the signal voltage on ECM
[78] terminal 49.

•

At low temperatures, the resistance is very high, allowing
the voltage to rise close to 5V. The ECM monitors this
voltage to compensate for various operating conditions.

Vehicle Speed Sensor (VSS)

The VSS is a Hall-effect device mounted close to the teeth of
the 5th gear in the transmission. The output signal frequency
varies with vehicle speed. The ECM processes the vehicle
speed signal and transmits it via the serial data circuit to the
speedometer to indicate vehicle speed.

HO2S: Front and Rear

The HO2S sensor detects unburned oxygen in the engine
exhaust. The output of the sensor is a voltage having a range
of about 0-1.0V. The normal output is 0.5V which represents
a balance between a lean (not enough fuel) and rich (too much
fuel) air/fuel mixture. An output less than 0.5V represents a
lean mixture; greater than 0.5V represents a rich mixture. The
change in output level signals the ECM to modify the air/fuel
ratio. This voltage is what is seen across the sensor. If the
voltage is measured from the sensor to ground or is displayed
on DIGITAL TECHNICIAN II (Part No. HD-48650) it will range
from 0.7-1.7V. This will cause the midpoint between rich and
lean to be 1.2V.

It is important to note the HO2S do not operate efficiently until
it is at operating temperature. Therefore, before any
troubleshooting takes place, bring the sensor to operating
temperature. Leaks in the exhaust system, leaky exhaust
valves, misfires or any engine problem allowing unburned
oxygen into the exhaust stream could create a DTC indicating
a bad sensor. Look for problems related to an improper air/fuel
mixture before replacing the sensor.

DRIVERS

The ECM drivers are the output devices or system outputs of
the EFI system. Drivers are provided ground by the ECM to
pump, inject and ignite the air/fuel mixture in the engine, and
to activate relays.

Fuel Pump

The fuel pump, located inside the fuel tank, is provided battery
voltage when the system relay is activated.

Ignition Coil and Spark Plugs

The ignition coil creates the energy to fire the spark plugs and
ignite the air/fuel mixture in the cylinders. Advancing or
retarding the spark is controlled by the ECM to suit load and
speed conditions of the engine.

See

Figure 1-14

. The ignition coil is provided power by the

system relay.

Fuel Injectors

The system relay provides battery power to the fuel injectors.
The ECM provides the path to ground to trigger the injectors.
The fuel injectors are pulse-width modulated solenoids for
metering fuel into the intake tract. The pulse-width of the ground
path to the injectors is varied by the ECM in response to inputs
from the various sensors, thus varying the length of time the
injector is open.

Start Relay

Pressing the start switch activates the start relay, sending
battery voltage to the starter solenoid. The TSM/TSSM/HFSM
controls the ground to the start relay, disabling it during security
and tip over conditions.

Purge Solenoid (If Equipped)

The purge solenoid allows vapors from the charcoal canister
to flow to the throttle body. The timing and amount of solenoid
opening depends on engine speed, vehicle speed, engine
temperature and throttle position.

TMAP: MAP Signal

The MAP signal varies in accordance with engine vacuum and
atmospheric pressure. Changes in atmospheric pressure are
influenced by weather and altitude.

TMAP: IAT Signal

The IAT portion of the TMAP sensor is a thermistor device,
meaning that at a specific temperature, it will have a specific
resistance across its terminals. As this resistance varies, so
does the voltage on terminal 49 of the ECM.

•

At high temperatures, the resistance of the IAT sensor is
very low, which effectively lowers the signal voltage on
terminal 49.

•

At low temperatures, the resistance is very high, allowing
the voltage to rise close to 5V. The ECM monitors this
voltage to compensate for various operating conditions.

PART NUMBER

VACUUM PUMP

HD-23738

Diagnostic Tips: MAP Portion of TMAP
Sensor

•

DTCs P0107 or P0108 will set if the MAP sensor signal
is out of range. DTC P0108 can only be detected with the
engine running.

•

MAP sensor output check. Using the VACUUM
PUMP (Part No. HD-23738), apply a vacuum to the pres-
sure port of the TMAP sensor. The MAP signal voltage
should lower as the vacuum is applied.

•

The TMAP and TGS are connected to the same reference
line (+5V Vref). If the reference line goes to ground or
open, multiple codes will be set (DTCs P0107, P0108,
P0122, P0123, P1501 and P1502).

Diagnostic Tips: IAT Portion of TMAP
Sensor

Check the following conditions:

•

Poor connection: Inspect ECM and harness connector
[78] for backed out terminals, improper mating, inoperative
locks, improperly formed or damaged terminals, poor ter-
minal- to-wire connection and damaged harness.

•

Perform

Wiggle Test

to locate intermittents: If connections and

harness check out OK, use a multimeter to check the IAT
sensor voltage reading while moving related connectors
and wiring harnesses. If the failure is induced, then the
IAT sensor voltage reading will change.

•

Shifted sensor resistance value: Compare the temper-
atures of the ET and IAT sensors with the engine at
ambient temperature in order to evaluate the possibility
of a shifted (out of calibration) sensor which may result in
driveability problems. The sensor temperatures should be
within 10 degrees of each other.

•

An intermittent may be caused by poor connection, rubbed
through wire insulation or an inoperative wire within the
wire's insulation.

•

A faulty sensor can negatively affect the signal voltage of
the other sensors sharing the same 5V reference. If the
wiring passes the following tests, disconnect one sensor
at a time on the 5V reference and verify the DTC is still
present. Additional DTCs will be set as each sensor is
disconnected, clear DTCs after this test. Be sure to per-
form this test before replacing a component.

1.3 DIAGNOSTICS AND TROUBLESHOOTING,

6-12 2011 Touring Diagnostics: Engine Management

DTC P0117, P0118

DESCRIPTION AND OPERATION

The ECM supplies and monitors a voltage signal terminal 51
to one side of the ET sensor. The other side of the ET sensor
is connected to a common sensor ground, which is also con-
nected to the ECM terminal 61.

The ET sensor is a thermistor device, which means that at a
specific temperature it will have a specific resistance across
its terminals. As this resistance varies, so does the voltage on
terminal 51.

•

At high temperatures, the resistance of the sensor is very
low, which effectively lowers the signal voltage on terminal
51.

•

At low temperatures, the resistance is very high, allowing
the voltage to rise close to 5V.

The ECM monitors this voltage to compensate for various
operating conditions.

Diagnostic Tips

Once the engine is started, the temperature should rise steadily.

An intermittent may be caused by a poor connection, rubbed
through wire insulation or an inoperative wire inside the insula-
tion.

Check the following conditions:

•

Poor connection: Inspect ECM harness connector [78]
for backed out terminals, improper mating, inoperative
locks, improperly formed or damaged terminals, poor ter-
minal-to-wire connection, loose sensor and damaged
harness.

•

Perform

Wiggle Test

to locate intermittents: If connections and

harness check out OK, use a multimeter to check the
engine temperature reading while moving related con-
nectors and wiring harness. If the failure is induced, the
engine temperature display will change.
