Is there a way to test the MultiAir to see if that's the problem
A MultiAir problem will usually set a code. You can do a compression test.

I ask because Im not sure what caused the car to stall in the middle of driving it in the first place
A MultiAir problem will usually set a code. You can do a compression test.
Well I went and tried starting it again. After a few times it actually roughly idled for few second. The check engine light came on (flashing). Turned it off and did another check for a code and it finally showed one P1039. Mentioned #2 cylinder. Anyone know what this code means? Also does anyone know where I can find the wiring diagram for the ECM?
I really appreciate all your help with my problem. I hope Im not being a headache or pain in the .....

P1039-CYLINDER 2 OIL SUPPLY SOLENOID VALVE DRIVER SHORT TO BATTERY

126344


Theory of Operation

Multi-Air is an electronically controlled variable intake valve phase and lift system. Unlike conventional intake valve phase and lift system which controls all the cylinder intake valves simultaneously and in the same proportion; Multi-Air, through the use of an electronically controlled “ hydraulic link” between the camshaft and intake valve, allowing for each intake valve to be controlled independently. The valve lift and timing can be adjusted infinitely.

The Multi-Air valve train has a mechanical camshaft lobe acting on a hydraulic pump located between the camshaft intake lobe and the intake valve. The pump provides oil under pressure to a two-way electro-hydraulic solenoid valve called the Variable Valve Actuator (VVA) Solenoid. The VVA Solenoid is electronically controlled during the specific intake cam lobe event by the Powertrain Control Module (PCM). During the event the VVA Solenoid is commanded to either hold oil pressure or bleed oil. The Variable Valve Actuator (VVA) Solenoid is a normally open solenoid. The PCM provides 12 volts to close the solenoid. The position of the VVA Solenoid determines the intake valve timing and lift. This change on valve action is similar to creating a change in the camshaft lobe profile affecting lift and duration of the valve opening.

When Monitored and Set Conditions

When Monitored: This diagnostic runs continuously when the following conditions are met:

•With the engine running.
•With no battery or ASD Relay DTCs active.

Set Conditions:

•When the Powertrain Control Module (PCM) detects a short to voltage in the Solenoid Signal or Return circuit.

Default Actions:

•The MIL light will illuminate.


Possible Causes

VARIABLE VALVE ACTUATOR SOLENOID SIGNAL CIRCUIT SHORTED TO VOLTAGE
VARIABLE VALVE ACTUATOR SOLENOID RETURN CIRCUIT SHORTED TO VOLTAGE
VARIABLE VALVE ACTUATOR SOLENOID
POWERTRAIN CONTROL MODULE (PCM)


Always perform the PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

1.CHECK FOR AN ACTIVE DTC

1. Start the engine and allow it to idle.

WARNING:
When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in possible serious or fatal injury.

2. With the scan tool, read DTCs and record on the repair order.

Is the DTC active or pending?

Yes

•Go To 2

No

•Perform the INTERMITTENT CONDITION diagnostic procedure. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).



2.CHECK THE (N34) VVA SOLENOID 2 SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE

1. Turn the ignition off.

2. Disconnect the VVA Solenoid 2 harness connector.

3. Disconnect the PCM C2 harness connector.

4. Check for continuity between the (N34) VVA Solenoid 2 Signal circuit and all other circuits at the PCM C2 harness connector.

Is there continuity between the (N34) VVA Solenoid 2 Signal circuit and any other circuit?

Yes

•Repair the (N34) VVA Solenoid 2 Signal circuit for a short to another circuit.
•Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

No

•Go To 3


3.CHECK THE (N35) VVA SOLENOID 2 RETURN CIRCUIT FOR A SHORT TO VOLTAGE

1. Check for continuity between the (N35) VVA Solenoid 2 Return circuit and all other circuits at the PCM C2 harness connector.

Is there continuity between the (N35) VVA Solenoid 2 Return circuit and any other circuit?

Yes

•Repair the (N35) VVA Solenoid 2 Return circuit for a short to another circuit.
•Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

No

•Go To 4


4.CHECK RELATED PCM AND COMPONENT CONNECTIONS

1. Perform any Service Bulletins that apply.

2. Disconnect all PCM harness connectors.

3. Disconnect all related in-line harness connections (if equipped).

4. Disconnect the related component harness connectors.

5. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
•Proper connector installation.
•Damaged connector locks.
•Corrosion.
•Other signs of water intrusion.
•Weather seal damage (if equipped).
•Bent terminals.
•Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
•Terminals that have been pushed back into the connector cavity.
•Check for spread terminals and verify proper terminal tension.

Repair any conditions that are found.

6. Reconnect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.

7. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.

8. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.

9. With the scan tool, erase DTCs.

10. Test drive or operate the vehicle in accordance with the when monitored and set conditions.

11. With the scan tool, read DTCs.

Did the DTC return?

Yes

•Replace the Powertrain Control Module in accordance with the Service information. (Refer to 08 - Electrical/8E - Electronic Control Modules/MODULE, Powertrain Control - Removal) .
•Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

No

•Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
•Test complete.

There is no single schematic for the PCM but there is a pinout:
