If the test light blinks while cranking, the PCM and
the wiring to the injectors are OK. The Fuel Injector
Coil Test Procedure will check if the injectors are
faulty.

7. Because the test light was “ON” steady, voltage to
the injector is OK, but the driver circuit is grounded
at all times. This step determines if the circuit is
shorted to ground or the PCM is faulty.
9. The reading should be about 12-14
.
10.Locating the open in the harness or in the injector
will require removal of the manifold to provide
access.

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 58X reference circuit at the PCM
harness connector while moving connectors and
wiring harnesses related to the ICM. 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.

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.
Diagnostic Aids
Check for the following conditions:

6E–207 ENGINE DRIVEABILITY AND EMISSIONS
Poor connection at PCM – Inspect the harness
connectors for backed-out terminals, improper mating,
broken locks, improperly formed or damaged
terminals, and poor terminal-to-wire connections.
Damaged harness – Inspect the wiring harness for
damage. If the harness appears to be OK, observe
Tech 2 display related to DTC P0351 while moving theconnector and wiring related to the ignition system. A
change in the display 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.
