DTC P0373, P0374
DESCRIPTION AND OPERATION
If the CKP sensor signal is weak or absent, DTCs P0373 or
P0374 will be set. DTC P0373 is usually set when several
attempts to crank the engine have failed.
NOTE
If signal is not detected or cannot synchronize (DTC P0374),
engine will not start.
Table 6-33. Code Description
DESCRIPTION
DTC
CKP sensor intermittent
P0373
CKP not detected/cannot synchronize
P0374
Diagnostic Tips
Engine must be cranked for more than five seconds without
CKP signal to set P0374 code. Intermittent TMAP wiring or
sensor issues may cause these codes to set prior to setting
TMAP codes. Verify TMAP wiring and sensor prior to replacing
the ECM.

2011 Touring Diagnostics: Engine Management 6-35
6.10
DTC P0444, P0445
DESCRIPTION AND OPERATION
Purge Solenoid (If Equipped)
See
. To comply with emission standards in some
areas, a purge solenoid is required. The purge solenoid is
located under the seat. Two vent lines run from the purge
solenoid. One line connects to the top of the fuel tank and the
other connects to a vent canister mounted to the vehicle
chassis in front of the purge solenoid. A second return line from
the vent canister connects to the air intake manifold allowing
vented fumes to be recirculated into the engine.
The purge solenoid is timed to the throttle position and is dis-
abled during startup, low engine temperature, low engine speed
or low vehicle speed. Power for the purge solenoid is supplied
by the system relay. The system relay also provides power for
the VSS, fuel pump and the ignition coil. The ECM provides a
path to ground to trigger the purge solenoid.
NOTES
•
System fuse and system relay failures or wiring harness
problems will cause 12V power to be lost to the VSS,
ignition coils, fuel pump and purge solenoid.
•
Purge solenoid is not installed on non-California vehicles
and DTCs P0444 and P0445 are not available. If these
DTCs appear, the ECM is improperly programmed and
should be reprogrammed.

DESCRIPTION AND OPERATION
. The VSS is powered and monitored by the
ECM. The ECM processes the vehicle speed signal and
transmits this signal to the TSM/TSSM/HFSM and speedometer
through serial data circuit.

DTC P0505
LOSS OF IDLE SPEED CONTROL
The throttle control actuator uses a two wire DC motor to move
the throttle plate from the spring loaded off-idle detent. The
ECM supplies a pulse width modulated voltage signal through
[78B] terminals 29 and 30. The ECM monitors throttle position
through the dual position sensors (TPS1 and TPS2).This code
will set if the throttle actuation faults cause the idle to become
unstable. This can be caused by a loose TPS, throttle actuator
friction or an intermittent air leak.
NOTE
Although the ECM monitors terminals 29 and 30, faults on
these terminals will not cause this DTC. Faults on these ter-
minals will be higher priority DTCs, address them first.

6-44 2011 Touring Diagnostics: Engine Management
6.13
DTC P0572
DESCRIPTION AND OPERATION
Brake Switch
There are two stop lamp switches. The front stop lamp switch
is a mechanical switch located on the right hand controls. The
rear stop lamp switch is a pressure switch located in the brake
line under the exhaust pipes.
On vehicles not equipped with ABS, when the stop lamp
switches are closed they supply power to the coil side of the
brake relay. This energizes the brake relay and supplies power
to the stop lamp. The stop lamp switches also supply an input
to the ECM.
On vehicles equipped with ABS, when the stop lamp switches
are closed each switch supplies a separate input to the ABS
module. Power is also supplied through the ABS diode pack
to the ECM (as a brake input) and to the brake relay. The brake
relay energizes and supplies power to the stop lamps.
During an ignition cycle, the ECM must receive a valid brake
switch input. During the same ignition cycle the vehicle has to
reach 31 mph (50 km/h) in third gear or higher and return to a
stop three times without any brake switch signals in order to
set DTC P0572.
Table 6-43. Code Description
DESCRIPTION
DTC
Brake switch input error
P0572
Diagnostic Tips
The accessory circuit supplies power to the stop lamp switches
and horn switch. A short to ground on the switch circuits will
cause the accessory fuse to open only when the switch is
applied. This includes a short in the ABS diode pack on ABS
equipped vehicles.
