This vehicle does not have a cam sensor .The ICM provides a synthesized cam signal to the PCM based on these inputs. The PCM uses the cam signal to synchronize fuel injection.
The powertrain control module (PCM) supplies a signal on each of the ignition control (IC) timing control circuits to the ignition control module (ICM). The ICM fires the correct ignition coil at the correct time based on the signals. The ICM detects if cylinder 1 or cylinder 3 is on the compression stroke by sensing the secondary voltage and polarity of each side of the ignition coil. The ICM detects this voltage with sensing circuitry integrated into each ignition coil. The higher voltage is on the compressing cylinder. This is called compression sense ignition. The ICM provides a synthesized cam signal to the PCM based on these inputs. The PCM uses the cam signal to synchronize fuel injection.
This system consists of the following circuits:
• An ignition voltage circuit
• A ground circuit
• A camshaft position (CMP) sensor signal circuit
• An IC timing control circuit for cylinders #1 and #4
• An IC timing control B circuit for cylinders #2 and #3
This ignition system does not use a conventional camshaft position (CMP) sensor that detects valve train position. The ignition controls module (ICM) detects when #1 or #3 cylinder has fired on the cylinders compression stroke using sensing circuitry integrated within each coil. The sensing circuit detects the polarity and the strength of the secondary voltage output, the higher output is always at the event cylinder. The ignition control module (ICM) sends a CMP signal to the powertrain control module (PCM) based on the voltage difference between the event and waste cylinder firing energy. This system is called compression sense ignition. By monitoring the CMP and crankshaft position (CKP) signals, the PCM can accurately time the operation of the fuel injectors. If the PCM receives an intermittent CMP signal from the ICM, the CMP Resync Counter on the scan tool will increment. When the PCM cannot use the information from the CMP signal, a DTC will set. DTC P0341 sets when the PCM detects too many CMP Resyncs within a certain amount of time.
Detach the wiring harness connector(s) from the ICM.
Remove the mounting bolts, then remove the ICM.
Position the ICM onto the inner fender apron and install the mounting bolts. Tighten the bolts to 22–31 inch lbs (2.5–3.5 Nm).
Attach the wiring harness connector(s) to the ICM.
Connect the negative battery cable.

Each ignition control module (ICM) has the following circuits: An ignition 1 voltage circuit
A chassis ground
An ignition control circuit for each cylinder
A low reference circuit
The PCM controls spark by pulsing the ignition control
circuits to the ICM to trigger the coils and fire the spark plugs. The
PCM and ICM are internally protected against shorts to power and ground
on the ignition control circuits.
The spark plugs are connected to
each coil by a short boot. The boot contains a spring that conducts the
spark energy from the coil to the spark plug. The spark plugs are
tipped with platinum for long wear and higher efficiency.

DO NOT wipe grease from the module or coil if the same module is
to be replaced. If a new module is to be installed, a package of
silicone grease will be included with the module. Spread the grease on
the metal face of the module and on the cover where the module seats.
This grease is necessary for module cooling.

Install the screws that retain the housing to the cover.
Install the spark plug boots and the retainers to the housing, if
Install the ICM assembly to the engine while carefully aligning
the spark boots to the spark plug terminals.
The ICM cover bolts must be installed using isolator washers with
the rubber side facing down.
Install the bolts that retain the ICM assembly to the camshaft
housing after coating the bolt threads with LOCTITE, or equivalent.

i have the same problem with my car i put a crank and cam sensor, a whole other coil pack, and an ignition control module the only thing i have left to do is put a computer in it. if you find a solution email me at firstname.lastname@example.org
