Conditions for Clearing the MIL/DTC
DTC P0341 can be cleared by using Tech 2 “Clear Info”
function or by disconnecting the PCM battery feed.
Diagnostic Aids
An intermittent may be caused by a poor connection,
rubbed-through wire insulation or a wire broken inside the
insulation. Check for:
Poor connection – Inspect the PCM harness and
connectors for 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, disconnect
the PCM, turn the ignition on and observe a voltmeter
connected to the CMP signal circuit at the PCM
harness connector while moving connectors andwiring harnesses related to the ICM and the CMP
sensor. A change in voltage will indicate the location
of the fault.
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.
Test Description
Number(s) below refer to the step number(s) on the
Diagnostic Chart.
2. Ensures that the fault is present.
12.Determines whether the fault is being caused by a
missing camshaft magnet or a faulty sensor. The
voltage measured in this step should read around 4
volts, toggling to near 0 volts when the CMP sensor
interfaces with the camshaft magnet.

ENGINE DRIVEABILITY AND EMISSIONS
Diagnostic Trouble Code (DTC) P0351 Ignition 1 Control Circuit
D06RW072
Circuit Description
The powertrain control module’s (PCM) control circuit 1
provides a zero-volt or a 5-volt output signal to the ignition
coil. The normal voltage on the circuit is zero volts. When
the ignition coil receives the 5-volt signal from the PCM, it
provides a ground path for the B+ supply to the primary
side of the number 1 ignition coil. When the PCM shuts off
the 5 volts to the ignition coil, the ignition coil turns “OFF.”
This causes the ignition coil primary magnetic field to
collapse, producing a voltage in the secondary coil which
fires the spark plug.
The circuit between the PCM and ignition coil is monitored
for an open circuit, short to voltage, and short to ground.
When the PCM detects a problem on ignition control
circuit 1, it will set a DTC P0351.
Conditions for Setting the DTC
The ignition is “ON.”
The engine is turning, determined by the 58X
crankshaft position input signal.
The output voltage is not equal to 5 volts when output
is “ON.”
The output voltage is not equal to 0 volts when output
is “OFF.”
Twenty test failures occur within 40 samples of
continuous spark events.
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 conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.
Conditions for Clearing the MIL/DTC
DTC P0351 can be cleared by using Tech 2 “Clear Info”
function or by disconnecting the PCM battery feed.

Conditions for Setting the DTC
Ignition voltage is between 11 and 16 volts.
Intake Air temp is more than 3C
At Engine revolution less than 600 RPM, EGR pintle
position indicates more than 21.5% and more than for
625 msecs.
Action Taken When the DTC Sets
The PCM will illuminate the malfunction indicator lamp
(MIL) after the second consecutive trip in which the
fault is detected.

Diagnostic Trouble Code (DTC) P0404 EGR Open Stuck
D06RW106
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
detect a fault if pintle position is different from
commanded position. If the PCM detects a pintle position
signal indicates more than 15 points different between
current and commanded and more than 15 seconds, the
PCM will set DTC P0404.
Conditions for Setting the DTC
Ignition voltage is between 11 and 16 volts.
Intake Air temp is more than 3C.
Desire EGR position is more than 0.
The difference between desired EGR and current EGR
is less than 3%.
Difference EGR pintle position between current and
commanded position becomes more than 15% and
last more than 15 seconds, and this condition meets
three times in a trip. Then it trigger, the PCM lights on.
Action Taken When the DTC Sets
The PCM will illuminate the malfunction indicator lamp
(MIL) as soon as failure detected after consecutive 2nd
trip in which the fault is detected.
The PCM will store conditions which were present
when the DTC was set as Freeze Frame and in Failure
Records data.
Conditions for Clearing the MIL/DTC
DTC P0404 can be cleared by using Tech 2 “Clear Info”
function or by disconnecting the PCM battery feed.
Diagnostic Aids
Check for the following conditions:
Excessive carbon deposit on EGR valve shaft may
cause EGR stuck open or unsmooth operation. Those
carbon deposit may occur by unusual port operation.
Clean up carbon may make smooth function of EGR
valve.
Poor connection or damaged harness – Inspect the
wiring harness for damage. If the harness appears to
be OK, observe the EGR actual position display on
Tech 2 while moving connectors and wiring harnesses
related to EGR valve. A change in the display will
indicate the location of the fault.
