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.

1 WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A

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?

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?
