Trouble Code: P1336
CKP Sensor System Variation Not Learned
Possible Causes:
Set the parking brake and block the drive wheels for safety.
Verify the hood is closed.
Read the trouble codes. If a code is set, refer to that code.
Start the engine. Allow engine temperature to reach at least 158?F (70?C). Then key off.
Select Crankshaft Position Variation Learn procedure on Scan Tool & start the vehicle.
Apply the brake pedal firmly and verify the selector is in Park.
Increase accelerator pedal position until fuel cutoff is reached at the test rpm (e.g., 5150). Quickly release the accelerator pedal after fuel cutoff is reached. The CKP system variation compensating values are learned when the engine speed (rpm) decreases back to idle speed and the procedure terminates.
Read the trouble codes and recheck for DTC P1336.
If DTC P1336 runs and passes, the CKP system variation "learn" procedure is complete. If not, look for other codes. If no codes are set, repeat the test procedure.

Here's the diagnostic procedure for DTC code 0340, directly from the service manual:

P0335 and P0336 Engine crank sensor malfunction
To test this code, have a visual inspection of the location and wirings of the crank sensor. If the engine has a cam sensor, you might mistook it as the crank sensor (it is a good idea to contact ATS that can research this for you). Check the sensor wires for insulation making sure it is getting a voltage signal as shown in the wiring diagram. Sometimes, the wires itself is soaked with dirty oil causing the sensor to fail. If OK, check the engine timing belt system for any slack which can also cause the sensor to throw in the code. If all of these prove OK, remove the crank sensor and check it for resistance as compared to the standard specs. Lots of times, if the sensor probe end is contaminated with oil or cracked, this can only be revealed after the crank sensor is removed

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

This is from updated GM service manual of mine.
According to the GM factory service manual, the OBD-II trouble code, P1336, is defined as follows: DTC P1336 CKP System Variation Not Learned. The factory service manual does not enumerate all of the symptoms of this trouble code, but after consulting a professional custom PCM tuner, it was learned that aside from the annoying light on the instrument cluster, the other symptoms exhibited may include: poor vehicle performance, and loss of misfire detection diagnostics.
This DTC is particularly nasty, because simply clearing it by disconnecting the battery, or clearing it using an OBD-II scan tool will not address the problem. The code will be set again later unless the vehicle is run through the actual "crank relearn" procedure.
Fixing the Dreaded P1336 DTC
There is only one way to properly fix the P1336 DTC, and that's to perform a "crank relearn" procedure, or as the GM factory service manual procedure calls it, the CKP System Variation Learn Procedure. This procedure can be initiated and performed by GM's be-all end-all scan tool, the Tech-2. It can also be performed by some aftermarket scan tools. Furthermore, some of the PCM tuning software applications are capable of initiating a "crank relearn" procedure.
