What has to be done to eliminate recurrent DTC P1336?


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.

Chevy express 1999 didn't start, i have a code p1336. i've change the crank shaft sensor but it didn't strat and i have a P1336 code again



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.

    Gmc 98 sonoma pu with p1336 error


    Hi there:

    The crankshaft position (CKP) system variation learn feature is used to calculate reference period errors caused by slight tolerance variations in the crankshaft, and the CKP sensors. The calculated error allows the powertrain control module (PCM) to accurately compensate for reference period variations. This enhances the ability of the PCM to detect misfire events over a wider range of engine speed and load.



    Conditions for Setting the DTC:
    The CKP system variation values are not stored in the PCM memory.




    Action Taken When the DTC Sets:
    The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
    The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.




    Conditions for Clearing the MIL/DTC:
    The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
    A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
    A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
    Clear the MIL and the DTC with a scan tool.
    Diagnostic Aids
    The CKP system variation values are not stored in the PCM memory after a learn procedure has been performed. If the actual CKP variation is not within the CKP system variation compensating values stored in the PCM, DTC P0300 may set.


    The CKP system variation learn procedure is also required when the following service procedures have been performed, regardless of whether DTC P1336 is set.
    An engine replacement
    A PCM replacement
    A harmonic balancer replacement
    A crankshaft replacement
    Any engine repairs which disturb the CKP sensor relationship
    If the CKP system variation learn procedure cannot be performed successfully, check for the following conditions and correct as necessary:
    A damaged reluctor wheel
    Excessive crankshaft runout
    A damaged crankshaft
    Interference in the signal circuit of the CKP sensor
    A coolant temperature that is not within the Conditions For Running the DTC




    The ignition switch is in the ON position until the battery is drained
    A PCM power disconnect with the ignition ON may erase the stored value and set the DTC P1336




    Hope this helps.

    How resolve a P1336 DTC on a 2005 Ford Freestar


    Do you have code P1336 and poor driveability (ie misfires, surging like the trans is drpopping in and out of overdrive). if so you may need to relearn the pcm?
    Did you by any chance change the plugs and wires, did you also replace the coil? Also, did you bump or pull the connector for the camshaft postion sensor? Could be it's just coincodence and the sensor just went. Not 100% sure, but I beleive that the cam sensor is used in a sequential fuel injection system to tell the ECU when to turn on an individual fuel injector. If the ECU doesn't detect a signal from the cam sensor, it will default to a batch fire mode, where all 3 injectors on either side of the engine will fire simultaneously causing misfires?
    If you can't reprogram the ecu replace the camshaft sensor.

    Engin light is on when i check it by computer it gives me error P1336 [25,10,13,36] , please refer to relevant terchnical manual


    The crankshaft position (CKP) system variation learn feature is used to calculate reference period errors caused by slight tolerance variations in the crankshaft, and the CKP sensors. The calculated error allows the powertrain control module (PCM) to accurately compensate for reference period variations. This enhances the ability of the PCM to detect misfire events over a wider range of engine speed and load.

    The code P1336 is for a Crankshaft (CKP) and/or Camshaft (CMP) position sensor input signal to PCM concert. It is triggered if the input signal to the PCM for either of these sensors is erratic. Per the factory service manual, this can be due to:
    - a damaged PCM
    - damaged CKP sensor
    - damaged CMP sensor
    - base engine
    - harness concerns.

    The service manual suggests checking the following items:
    - harness routings,
    - alterations,
    - improper shielding,
    - or electrical interference from other improperly functioning systems.

    To properly check the operation of the CMP and CKP, you'll really need an oscilloscope. The code is probably being triggered due to a faulty sensor or connection and not something that just needs to be reset.

    Step / Action / Yes / No

    1. Did you perform the Diagnostic System Check-Engine Controls?
    Yes: Go to Step 2
    No: Go to Diagnostic System Check - Engine Controls

    2. Preform the CKP system variation learn procedure. Refer to CKP System Variation Learn Procedure. Did you complete the action?
    Yes: Go to Step 3
    No: Go to Diagnostic Aids

    3. Clear the DTCs with a scan tool.
    Turn OFF the ignition.
    Start the engine.
    Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text.
    Does the DTC run and pass?
    Yes: Go to Step 4
    No: Go to Step 2

    4. With a scan tool observe the stored information, Capture Info.
    Does the DTC run and pass?
    Yes: Go to Diagnostic Trouble Code (DTC) List
    No: System OK


    Diagnostic Aids:
    The CKP system variation values are not stored in the PCM memory after a learn procedure has been performed. If the actual CKP variation is not within the CKP system variation compensating values stored in the PCM, DTC P0300 may set.

    I have a p1336 code. is it a bad sensor or a wire problem ?


    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.

    ^ Block the drive wheels.
    ^ Cycle the ignition from OFF to ON.
    ^ Apply and hold the brake pedal.
    ^ Start and idle the engine.
    ^ Turn OFF the A/C.
    ^ Place the vehicle's transmission in Park (A/T) or Neutral (M/T).
    ^ The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. The scan tool only
    displays the condition that inhibits the procedure. The scan tool monitors the following components:
    - Crankshaft position (CKP) sensors activity - If there is a CKP sensor condition, refer to DTC P0335 or DTC P0336.
    - Camshaft position (CMP) sensor activity- If there is a CMP sensor condition, refer to DTC P0341, DTC P0342 or DTC P0343.
    - Engine coolant temperature (ECT) - If the engine coolant temperature is not warm enough, idle the engine until the engine coolant
    temperature reaches the correct temperature.
    7. With the scan tool, enable the crankshaft position system variation learn procedure.
    IMPORTANT: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is
    returned to the operator and the engine responds to throttle position after the learn procedure is complete.
    8. Slowly increase the engine speed to the RPM that you observed.
    9. Immediately release the throttle when fuel cut-off is reached.
    10. The scan tool displays Learn Status: Learned this ignition. If the scan tool does NOT display this message and no additional DTCs set, refer to
    Symptoms - Engine Mechanical. If a DTC set, refer to Diagnostic Trouble Code (DTC) List for the applicable DTC that set.
    11. Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.
