It could be a bad cam sensor, your voltages are good, but the out of sync code can be a tough one. You need an oscilloscope to test the square wave pattern. This code can be a sensor, timing chain, or the most common, a bad flex plate. When the flex plates break/crack, it throws off the timing window, thus giving you an out of sync cam and crank sensor reading. I usually measure the crank and cam square wave patterns and then measure the milliseconds difference between the cam and crank. This may be to in depth, but this is one of those problems that this comes in handy and is sometimes necessary.
Here is a diagnostic tree for this and some of the possibilties.
P0016-CRANKSHAFT/CAMSHAFT TIMING MISALIGNMENT
When Monitored: Engine cranking and Engine running
Set Condition: Powertrain Control Module detects an error when the camshaft position is
out of phase with the crankshaft position. One trip fault.

TEST ACTION APPLICABILITY
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE
PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
Ignition on, engine not running.
With the DRBIIIt, read DTCs and record the related Freeze Frame data.
With the DRBIIIt, erase DTCs.
Start the engine and run until operating temp is reached. (Closed Loop)
If the DTC does not reset it may be necessary to take the vehicle on a test drive.
Does the DTC reset?
Yes ! Go To 2
No ! Refer to the INTERMITTENT CONDITION symptom in the
Perform POWERTRAIN VERIFICATION TEST VER - 5.
2 Turn the ignition off.
With the DRBIIIt lab scope probe and the Miller special tool #6801, backprobe the
(K44) CMP Signal circuit at the CMP harness connector.
WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A
Start the engine.
Observe the lab scope screen.
Are there any irregular or missing signals?
Yes ! Go To 3
No ! Go To 6
3 Visually inspect the related wire harness. Look for any chafed, pierced, pinched, or
partially broken wires.
Visually inspect the related wire harness connectors. Look for broken, bent, pushed
out, or corroded terminals.
Ensure the Crankshaft Position Sensor and the Camshaft Position Sensor are
properly installed and the mounting bolt(s) tight.
Refer to any TSBs that may apply.
Were any of the above conditions present?
Yes ! Repair as necessary
No ! Go To 4
4 Turn the ignition off.
Remove the Camshaft Position Sensor.
Inspect the Tone Wheel/Pulse Ring for damage, foreign material, or excessive
Were any problems found?
Yes ! Repair or replace the Tone Wheel/Pulse Ring as necessary.
No ! Go To 5
5 If there are no possible causes remaining, view repair. All
Replace the Camshaft Position Sensor.
Gently tap on the Cam Position Sensor and wiggle the Sensor.
Inspect the Sensor harness connector, PCM harness connector, Sensor connector, and
PCM connector for loose, bent, corroded, or pushed out pins/terminals.
Inspect the related wire harness and the splices in the (K44) CMP circuits.
Did the DTC reset?
Yes ! Repair the wiring/connector concerns as needed or replace the
Camshaft Position Sensor.
No ! Go To 7
7 Turn the ignition off.
(K24) CKP Signal circuit at the CKP harness connector.
Yes ! Go To 8
No ! Go To 11

No ! Go To 9
9 Turn the ignition off.
Remove the Crankshaft Position Sensor.
Inspect the Tone Wheel/Flex Plate slots for damage, foreign material, or excessive
Yes ! Repair or replace the Tone Wheel/Flex Plate as necessary.
No ! Go To 10
10 If there are no possible causes remaining, view repair. All
Replace the Crankshaft Position Sensor.
following test may help in identifying the intermittent condition.
Gently tap on the Crank Position Sensor and wiggle the CKP Sensor.
