DIAGNOSTIC TROUBLE CODE (DTC) P0352
CYLINDER 3/4 (2/3-2.3L DOHC) COIL: IGNITION DRIVER OUTPUT CIRCUIT
CHECK
Circuit Description
The Engine Control Module (ECM) provides a ground for
the ignition coil control circuit. When the ECM removes
the ground path of the ignition primary coil, the magnetic
field produced by the coil collapses. The collapsing
magnetic field produces a voltage in the secondary coil,
which fire two spark plugs at the same time on
”companion” cylinders, i.e. cylinders with pistons at
top of the their stroke (TDC) at the same time. One of
these pistons would be at the top of its compression
stroke, the other piston would be at the top of its exhaust
stroke.
The circuit between the ECM and the electronic ignition
system ignition coil is monitored for an open circuit,
short to voltage, and short to ground. When the ECM
detects a problem in the ignition coil No. 2 circuit, it will
set Diagnostic Trouble Code (DTC) P0352
Conditions for Setting the DTC
•••••
Current threshold (less than 5.8A) not reached in time.
Action Taken When the DTC Sets
•••••
The MIL will illuminate after two consecutive driving
cycles in which the diagnostic runs with the fault ac-
tive.
•••••
The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
•••••
A history DTC is stored.
Conditions for Clearing the MIL/DTC
•••••
The MIL will turn off after three consecutive driving
cycles in which the diagnostic runs without a fault.
•••••
A history DTC will clear after 40 consecutive warm-
up cycles without a fault.
•••••
The DTC(s) can be cleared by using the scan tool.
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 ECM harness and con-
nectors 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
