DTC P1353, P1356, P1357, P1358

DESCRIPTION AND OPERATION

See

Figure 6-31

. A feedback voltage signal in the secondary

ignition circuit (terminal B) detects the presence of combustion
each time a cylinder fires on ECM terminal 33. For diagnostic
purposes, this signal is only analyzed at high speed and load
conditions where it may be easily measured. Failure to detect
combustion at high speed and load means one of following
conditions is true:

•

Cylinder is truly misfiring.

•

There is a lack of continuity in the ignition coil secondary
circuit.

NOTE

Make sure vehicle is running properly before performing the
tests in this section. Perform fuel pressure tests if required.
See the service manual. If fuel pressure is not within the proper
range, see

Table 6-63. Code Description

6.22

DTC P1501, P1502

DESCRIPTION AND OPERATION

See

Figure 6-36

. The Jiffy Stand Sensor (JSS) uses a Hall-

effect sensor to monitor jiffy stand position. When the jiffy stand
is fully retracted the sensor picks up the presence of the metal
tab mounted to the jiffy stand. The metal tab is moved away
from the sensor as the jiffy stand is extended. When the jiffy
stand is extended the engine will only start and run if the
TSM/TSSM/HFSM determines the transmission is in neutral.
Otherwise the engine will stall as the clutch is released. This
is done by monitoring the neutral switch input to the
TSM/TSSM/HFSM and communicating that input over the serial
data circuit to the ECM.

The JSS is powered and monitored by the ECM. The ECM
supplies the 5V reference to the JSS. The JSS sends a signal
back to the ECM. This signal is used by the ECM to determine
when the jiffy stand is retracted or extended. The JSS is
grounded through the ECM.

The JSS also has a Fail Enable Mode. This mode allows the
engine to start and run if the system recognizes a problem with
the JSS circuit. When a problem exists or if the transmission
is put in gear with the jiffy stand extended, the odometer will
display "SIdE Stand". DTC P1501 or P1502 will set if the JSS
circuits are out of range.

NOTE

The ECM supplies 5V reference voltage to the VSS, TPS and

6-74 2011 Touring Diagnostics: Engine Management

6.23

DTC P1510, P1511, P1512

DESCRIPTION AND OPERATION

Throttle Actuation Control Management

The ECM constantly monitors throttle actuation and throttle
component positioning. Several safety features are pro-
grammed into the ECM to limit performance when an error or
fault in throttle actuation is detected. These DTCs always
accompany another code. Refer to

Table 6-74

Table 6-74. Code Description

DESCRIPTION

DTC

Throttle actuator control limited perform-
ance mode

P1510

Throttle actuator control power manage-
ment mode

P1511

Throttle actuator control forced idle mode

P1512

Performance limitations are identified by code, as follows:

•

P1510 Limited Performance: Enables near normal
operation of the vehicle, guarding against inadvertent wide
open throttle conditions. Typically this code is the result if
one of the TGS or TP sensors, or one of each, has failed.

•

P1511 Power Management: Provides more limitation on
driveability, due to failure of the TCA, without a TGS, MAP
or airflow faults. The TCA is de-energized and the throttle
plate returns to its idle detent position. The ECM monitors
the operation of the TGS and adjusts the spark advance

and cylinder shutoff/rev limiting, allowing the vehicle to
reach traffic speeds (limp-home).

•

P1512 Forced Idle Mode: Provides extreme limitation of
driveability, due to a failure of both TGS, TGS validation
error or failure of one TGS and the brake switch. The TCA
is de-energized and the throttle plate is forced to a fast
idle position providing enough torque to operate at a high
idle speed.

DTC P1514

DESCRIPTION AND OPERATION

Air Flow Fault

The ECM uses the TMAP sensor to monitor air flow past the
throttle plate. This ensures proper throttle plate positioning,
when the throttle is released and allowed to return to the
unpowered position. The unpowered position is typically 7%
of throttle plate range.

In order to avoid inconsistent readings at low rpm (or at idle),
testing air flow is only performed at engine speeds above
normal idle (10% of throttle plate range or approximately 1300
rpm).

The ECM compares the intake manifold pressure value from
the TMAP to the throttle plate position value from the TPS.
DTC 1514 sets if the manifold pressure is higher than it should
be for that given throttle plate position for three consecutive
ignition cycles. If a TMAP sensor error is present, then the
ECM does not check P1514 parameters and instead P2105
(forced shutdown mode) is initiated, shutting down the fuel
pump and fuel injectors. See

6.28 DTC P2105, P2107

. The

ECM only checks for DTC P1514 if power management mode
(DTC P1511) is present.

DTC P1600

DESCRIPTION AND OPERATION

The ECM uses a main microprocessor and a monitoring
microcontroller, to communicate with the throttle actuation
control system.

The microcontroller monitors the main microprocessor of the
ECM, and when a communication failure is identified, the
microcontroller shuts down the TCA and fuel injectors.

An internal ignition delay timer monitors when the ignition circuit
is energized. The microcontroller issues DTC P1600 if no
communication is established between the main microprocessor
or if a monitoring failure occurs within three consecutive ignition
cycles.
