The following service procedures require either a programming or a setup event performed for a complete repair.
ECM Replacement
Important: It is not necessary to program a new engine control module (ECM). The ECM is programmed from the factory. Ensure the new ECM is equipped with the latest software/calibration.
If the engine control module (ECM) is replaced, the following procedures must be performed:
Idle Learn Procedure--Refer to the appropriate procedure:
• Idle Learn for the 1.4L DOHC engine
• Idle Learn for the 1.4L SOHC engine
• Idle Learn for the 1.6L engine
The crankshaft position (CKP) System Variation Learn Procedure-- Refer to the appropriate procedure:
• Crankshaft Position System Variation Learn for the 1.4L DOHC engine
• Crankshaft Position System Variation Learn for the 1.4L SOHC engine
• Crankshaft Position System Variation Learn for the 1.5L engine
• Crankshaft Position System Variation Learn for the 1.6L engine
Theft Deterrent--Refer to Programming Theft Deterrent System Components . The ECM will learn the incoming fuel continue password immediately upon receipt of a password message. Once a password message is received, and a password is learned, a learn procedure must be performed to change this password again. An ECM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password, and will require a learn procedure after programming to learn the current vehicle's password.

P1336 gm code


P1335 CHEVROLET P1335 CHEVROLET - Crankshaft Position Circuit Possible causes
- Faulty Crankshaft Position Sensor
- Crankshaft Position (CKP) Sensor harness is open or shorted
- Crankshaft Position (CKP) Sensor circuit poor electrical connection help.png Help with this
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
P1335 CHEVROLET Description
The Crankshaft Position (CKP) sensor sends pulses to the Powertrain Control Module (PCM) as the reluctor wheel teeth rotate past the CKP sensor. The PCM uses the CKP pulses to synchronize the ignition and fuel injector operation, and to time the interval between each CKP pulse. The PCM determines when an excessive change in crankshaft speed occurs by comparing each new time interval with the previous interval. A misfire causes an unexpected change in the crankshaft speed. A certain amount of acceleration/deceleration is expected between each firing stroke, but if the crankshaft speed changes more than an expected amount, the PCM interprets this as a misfire. The interval between CKP sensor pulses is extremely small. At high engine speeds, slight variations in the following components make misfire detection difficult:
- Crankshaft
- Reluctor wheel
- CKP sensor
The PCM learns variations during the Crankshaft Position System Variation Learning Procedure. The PCM compensates for these variations when performing detect misfire calculations. Only a scan tool can command the PCM to perform the Crankshaft Position System Variation Learning Procedure again.
Perform the learning procedure after the following actions:
- A PCM replacement
- Any operation or repair involving the crankshaft, the CKP sensor, or the CKP sensor to reluctor wheel gap relationship.
- An engine replacement.
- The ignition switch is in the ON position until the battery is drained.

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.

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.

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 helps.
