6VE1 3.5L ENGINE DRIVEABILITY AND EMISSIONS

Diagnostic Trouble Code (DTC) P1295 Power Management Mode

D06RY00088

Circuit Description

The throttle position (TP) 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 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 that if the systm is in
PowerManagement Mode.(Fail safe Mode)

Conditions for setting the DTC

The ignition is “ON”.

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

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 P1295 will clear after 40 cosecutive trip
cycle during which the warm up cycles have occurred
without a fault.

DTC P1295 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 connectons.

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

6E–402

6VE1 3.5 ENGINE DRIVEABILITY AND EMISSIONS

TP sensor 1, TP sensor 2 display on the Tech 2 while
moving connectors and wiring harnesses related to the
sensor.
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
DTC was last set.

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

P1295 Diagnostic Chart may isolate the cause of the
fault.

P1299 ETC Forced Engine Shutdown Mode

D06RY00088

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

been run and the fault condtion is no longer present.

A history DTC P1299 will clear after 40 cosecutive trip
