If both cam/crank position sensors have ONLY been unbolted and replaced with new sensors, do they require synchronization?

Did you reset the code after the replacement?

Camshaft / Crankshaft Sensor is the reason for the code. They come in different qualities. OEM is best, made in Mexico is the worst!

P1336 Crank Cam Sensor Range Performance

The first thing you probably should do is get a copy of the shop manual for your year and model. The manual would have the actual test procedures for the code.
You probably know code 1336 means the signal from the cam and crank sensors is not aligned, meaning the cam timing is off as far as the engine computer can see.
It could have been one of the sensors, but you normally get another code for that sensor too. It could also be a timing chain problem, or a wiring problem going back to the computer.

P1336 Ford P1336 Ford - Crankshaft Position Or Camshaft Position Sensor Input Signal Error Share
0 ' Add Comment Possible causes
- Faulty Crankshaft Position Sensor
- Faulty Camshaft Position Sensor
- Crankshaft Position Sensor harness is open or shorted
- Crankshaft Position Sensor circuit poor electrical connection
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
What does this mean? When is the code detected?
The Engine Control Module (ECM) has detected a synchronization or signal error from the cam or crank sensors
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
- Engine difficult to start
P1336 Ford Description
The input signal to the powertrain control module (PCM) from the crankshaft position (CKP) sensor or the camshaft position (CMP) sensor is erratic.

There are two possibilities...

1. The crankshaft and camshaft sensors are not properly synchronized to each other. This is a procedure that must be performed with special tools.
2. A bad alternator diode can cause this code to set due to voltage ripple. Have the alternator/charging system tested.

Here's what I've found about this P1336 code:
P1336 Crankshaft sensor is out of sync with camshaft sensor test
If you get this code, the first thing to check is your distributor especially if you have an imported vehicle. Look for signs of oil in the distributor which can contaminate the signals being monitored by the ECM (engine computer). Check also the wiring leading to the distributor and see if the wires are properly insulated away from hot exhaust which could burn the wires. Check also on the crank sensor location whether it is located in the front of the engine or at the flywheel at the rear of the engine. The same can be done for the cam sensor.
On engines with distributor, the cam sensor is usually located in the distributor and it will give you a lot of grief if not properly align and synchronize with the crank sensor. On some applications (like Ford), an alignment tool is required which is can be bought from your local parts store (cost about $31). If you install the distributor without proper timing, it will still run but the mileage will suffer and the above code showing up.
Your local trusted mechanic or Ford Dealer should be able to resolve this for you (if you can't) without too much trouble.

did you check the cam sensor or cap and rotor

Damaged CMP sensor. (camshaft position sensor)

P1336 - Crank / Cam Sensor Range / Performance.
The code P1336 is in most cases set due to a Mis-Adjusted Camshaft Position Sensor (CMP) Synchronizer.Ford makes a special tool to perform the alignment of the synchronizer assembly at top dead center or #1 cylinder compression stroke.

If you get this code, the first thing to check is your distributor especially if you have an imported vehicle. Look for signs of oil in the distributor which can contaminate the signals being monitored by the ecm (engine computer).Check also the wiring leading to the distributor and see if the wires are properly insulated away from hot exhaust which could burn the wires. Do these checks also on the crank sensor itself whether it is located in the front of the engine or at the flywheel at the rear of the engine. Ditto for the cam sensor.

On engine with distributor, the cam sensor is usually located in the distributor and it will give you a lot of grief if not properly align and synchronize with the crank sensor. On some applications (like Ford), an alignment tool is required which is can be bought from your local parts store (cost about $31). If you install the distributor without proper timing, it will still run but the mileage will suffer and the above code showing up.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

I would think it would be just the Camshaft Position Sensor.I looked up the codes and they say pretty much the samething.
