A change in the display will indicate the location of
the fault.If DTC P1295 cannot be duplicated, the
information included in the Faillure Records data can

be useful in determined vehicle mileage since the

If it is determined that the DTC occurs intermittently,
performing the DTC

RODEO 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

Diagnostic Trouble Code (DTC) P1299 ETC Forced Engine Shutdown Mode

D06RY00111

Circuit Description

The throttle position sensor circuit provides a voltage
signal relative to throttle position (blade angle).
The throttle blade angle will vary 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
laege quantitiy of air entering the engine indicates an
accleration 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 ditects if the system is in ECT Forced Engine
Shutdown Mode.(Fail safe Mode)

Conditions for setting the DTC

The ignition is “ON”.

ECT Forced Engine Shutdown Mode is active. (Fail
safe Mode)

Action Taken When the DTC Sets

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 “OFF” on the third
consecutive trip cycle during which the diagnostic has
been run and the fault condtion is no longer present.

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

DTC P1299 can be cleared using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.

Diagnostic Aids

An intermittent may be caused by the following:

Poor connections.

Mis routed harness.

Rubbed through wire insulation.

Broken wire inside the insulation.

Check for the following conditions:

Poor connection at PCM-Inspect harness connectors
for backed out terminals, improper mating, broken
locks, improperly formed or damaged terminals,and
poor terminal to wire connection.

Damaged harness-Inspect the wiring harness for
damage. If the harness appears to be OK, observe the
TP sensor 1, TP sensor 2 display on the Tech 2 while

RODEO 6VD1 3.2L ENGINE DRIVEABILITY AND EMISSIONS

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.

Conditions for setting the DTC

Ignition voltage is between 10volt and 16 volts.

MAP sensor signal is between 26kPa and 100 kPa.

Fuel level is more than 19%.

Engine speed is between 650rpm and 6500rpm.

No Crank DTCs set.

No System voltage DTCs set.

Action Taken When the DTC Sets

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

The PCM calculates an air flow value based on idle air
control valve position, throttle position, RPM and
barometric pressure.

The PCM will store conditions 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 “OFF” on the third
consecutive trip cycle during which the diagnostic has
been run and the fault condition is no longer present.

A history DTC P1310 will clear after 40 consecutive trip
cycle during which the warm up cycles have occurred
without a fault.

DTC P1310 can be cleared using the Tech 2 “Clear
Info” function or by disconnecting the PCM battery
feed.
