P1299 ETC Forced Engine Shutdown Mode
060R200061
Circuit Description

The throttle position sensor circuit provides a voltage
signal relative to throttle position (blade angle).
The throttle blade angle will vary from about 8% at
closed throttle to about 92% at wide open
throttle(WOT).

The DC motor circuit provides a voltage signal relative
to command throttle position (blade angle).

The mass air flow (MAF) sensor measures the amount
of air which passes through it into the engine during a
given time. The powertrain Control Module (PCM)
uses the mass air flow information to monitor engine
operating conditions for fuel delivery calculations. A
large quantity of air entering the engine indicates an
accelerator or high load situation, while a small quantity
or air indicates deceleration or idle.
The MAF sensor produces a frequency signal which
can be monitored using a Tech 2. The frequency will
vary within a range of around 4 to 7g/s at idle to
around 25 to 40g/s at maximum engine load.

This DTC detects if the system is in ETC Forced
Engine Shutdown Mode.(Fail safe Mode)
Conditions for setting the DTC

The ignition is ªONº.

ETC Forced Engine Shutdown Mode is active. (Fail
safe Mode)
Action Taken When the DTC Sets

The PCM will illuminate the malfunction indicator lamp
(MIL) the first time the fault is detected.

The PCM will store condition which were present when
the DTC was set as Freeze Frame and in the Failure
Records data.
Conditions for Clearing the MIL/DTC

The PCM will turn the MIL ªOFFº on the third
consecutive trip cycle during which the diagnostic has
been run and the fault condition is no longer present.

A history DTC P1299 will clear after 40 consecutive trip
cycles during which the warm up cycles have occurred
without a fault.

DTC P1299 can be cleared using the Tech 2 ªClear
Infoº function or by disconnecting the PCM battery
feed.
Diagnostic Aids
An intermittent may be caused by the following:

Poor connections.

Misrouted harness.

Rubbed through wire insulation.

Broken wire inside the insulation.

Diagnostic Trouble Code (DTC) P1310 ION Sensing Module Diagnosis
060R200068
Circuit Description
The Power Control Module (PCM) checks the validity of
the signals used in the ION Sensing module at the
following engine operating conditions.

The Deceleration Fuel Cut Off (DFCO) test is
performed to evaluate the Combustion Quality (CQ)
signal pulse width

If it is below a predetermined value, the value it is
expected to be during DFCO conditions. If the CQ
signal pulse width is above the predetermined
threshold, the fail counter will be incremented. If the
failure counter exceeds the calibration, then the test is
complete and a failure will be reported.

The Power Enrichment (PE) test is performed to
evaluate the Combustion Quality (CQ) signal pulse
width

If it is below a predetermined value, the value is
expected to be during PE conditions.
If the CQ signal pulse width is above the
predetermined threshold, the fail counter will be
incremented. If the failure counter exceeds the
calibration, then the test is complete and a failure will
be reported.

The Combustion Quality (CQ) test is performed to
check if inappropriate (CQ) signal status were
detected. If missing CQ pulses or multiple CQ pulses
or CQ pulse width calculation errors were detected, the
fail counter will be incremented. If the failure counter
exceeds the calibration, then the test is complete and
a failure will be reported.

Diagnostic Trouble Code (DTC) P1404 EGR Stuck Closed
060R200050
Circuit Description
The powertrain control module (PCM) monitors the EGR
valve pintle position input to ensure that the valve
responds properly to commands from the PCM, and to

position for more than 5 seconds, and this condition exists
3 times during trip, then the PCM will set DTC P1404.
Conditions for Setting the DTC

Ignition voltage is between 11 and 16 volts.

Intake Air temp is more than 3
C.

Desired EGR position is more than 3 %.

Difference of EGR pintle position between current and
the learned zero is more than 30 % for more than 5
seconds, and exists three times to the above condition
during a trip the PCM will set DTC 1404. Then it trigger
the PCM light on.
Action Taken When the DTC Sets

feed.
Diagnostic Aids
Check for the following conditions:

Excessive carbon deposit on EGR valve shaft and/or
foreign material may cause the EGR valve not to fully
seat. The carbon deposit may occur by unusual port
operation. Remove foreign material and/or excessive
carbon deposit on EGR valve shaft and to allow the
EGR valve to be fully seated.

Poor connection or damaged harness ± Inspect the
wiring harness for damage.
Reviewing the Failure Records vehicle mileage since the
diagnostic test last failed may help determine how often
the condition that caused the DTC to be set occurs. This
may assist in diagnosing the condition.
