Active Intake System
The active intake system utilizes a solenoid in the airbox which
is connected to the throttle valve via a cable. The throttle valve
is automatically closed by the solenoid under certain conditions
to reduce engine noise.
A code 22 will set if the ECM detects that the output for the
active intake control is not in agreement with the feedback cir-
cuit (minimum TP sensor voltage when actuated).
Likely causes for a code 22 are:
• Mechanical fault in the active intake solenoid, throttle
valve, or cable.
• Electrical fault in the solenoid circuit.
• Electrical fault in the throttle position sensor circuit.
• When TPS reading is not between 10.4-10.9 when activ-
ated.
Diagnostic Notes
The reference numbers below correlate with the circled num-
bers on the Code 22 flow charts.
Using TEST CONNECTOR KIT (Part No. HD-41404), attach
Brown pin probe and patch cord to [179] (1,2).
VERIFY SETTINGS
1. Prior to verifying the active intake system, check the
throttle position sensor (TPS) zero and adjust if necessary.
See **Throttle Position Sensor".
2. Leave Digital Technician attached to vehicle.
3. In Digital Technician, go to Active Intake test screen.
4. Rotate throttle grip to wide open throttle (WOT).
a. Check that when the throttle plate reaches WOT, TPS
should read above 82°.
b. If not, see WOT CHECK listed below.
5. While holding the throttle wide open, activate the active
intake tab on Digital Technician.
a. Verify that the TPS setting is between 10.4-10.9
degrees.
b. If settings are not correct proceed to cable adjustment
procedure.
WOT CHECK
1. Remove cosmetic intake cover assembly and functional
air cleaner cover. See
2.38 INTAKE COVER and 1.14 AIR
CLEANER AND EXHAUST SYSTEM .
2. While holding the throttle grip to the WOT position, verify
that the throttle plate is fully open.
If the throttle plate does not fully open, see E.1 ACTIVE
INTAKE SYSTEM (JAPANESE MODELS ONLY), Cable this
section.
CABLE
Adjustment
1. Remove cosmetic intake cover assembly and functional
air cleaner cover. See
2.38 INTAKE COVER and 1.14 AIR
CLEANER AND EXHAUST SYSTEM .
2. See Figure E-1 . Inspect for proper retraction freeplay in
solenoid shaft:
a. Open the throttle to the WOT position, push solenoid
shaft (1) inward to the fully retracted position.
b. While slowly rolling off the throttle you should be able
to move the solenoid shaft slightly inward until the
shaft bottoms out. This slight travel will be the retrac-
tion freeplay.
c. If you have no travel in the shaft, adjust cable housing
(4) away from the solenoid bracket (3) until freeplay
is achieved.
NOTE
This freeplay is necessary for the solenoid to properly function.
Freeplay should be 1/32 in. (0.79 mm) or greater.
