How to Perform a Crankshaft Variation Relearn Procedure

how to perform a crankshaft variation relearn procedure 17577

To begin the crankshaft variation relearn procedure, turn off the engine and hold the brake pedal for 30 seconds. Then, start the vehicle, and make sure to turn off the air conditioning. Put the car in either park or neutral, and turn on the vehicle’s engine controls. While the vehicle is running, hold down the throttle and let go once the fuel cutoff occurs. When the process completes, the scan tool display will read “Test In Progress.”

The next step is to turn off the engine. Make sure the vehicle is in Park or Neutral and the transmission is in Drive. Then, turn on the scan tool and wait for it to complete the procedure. The engine should now run smoothly. Depending on the vehicle, the engine must be shut off for 15 seconds in order for the scan tool to detect the malfunction. A successful relearn will indicate a DTC P0315.

If the DTC appears, the engine is too cold. The CKP sensor is responsible for indicating the condition. Once the CKP sensor is active, the scan tool will display it in the diagnostic window. If the signal is a failure of a particular component, the DTC P0315 is stored in the memory. If you have a malfunctioning crankshaft sensor, you can use a crankshaft variation relearn procedure scan to fix the problem.

The next step is to use a crankshaft variation relearn procedure scan to diagnose the problem. To complete the CKP VPP, you need to bring the engine to operating temperature, apply the brakes, and then release the throttle. Once this is completed, the ECC will return control of the engine to the driver. After 15 seconds, you can remove the scanner and test the car to see if the problem has resolved itself.

The procedure is important because the crankshaft variation relearn procedure can cause the engine to stall. It may be necessary to replace the crankshaft sensor. The procedure can take as long as 10 minutes. To complete the process, you must stop the engine and disconnect the scanner. During the process, the scanner should display the signal. After the test is complete, the DTC is stored in the memory of the vehicle.

To perform a crankshaft variation relearn procedure, you must ensure that the vehicle is cold. In order to properly perform the test, the engine should be in neutral or park mode. If the car is already running, it should be fine. Once it is stopped, turn off the engine and check the coolant level. When the engine is shut down, the oil should be at the proper level.

Before attempting the crankshaft variation relearn procedure, you should make sure that the engine is running at a safe operating temperature. Then, select the Relearn button and release the throttle. If the car starts to decelerate, the CKP fuel cutoff will activate. At this point, the scan tool will show the CKP Variation learn procedure, and the engine should run smoothly.

The first step is to turn off the engine and use the crankshaft variation relearn procedure scan. Before performing the scan, turn the car off and close it. Then, connect the scanner to the vehicle and begin the crankshaft variation relearn procedure. The CKP sensor activity will indicate if the engine has any problem. It will be necessary to shut off the engine during this procedure to prevent damage to the engine.

Before beginning the crankshaft variation relearn procedure, make sure that the vehicle is in park and that the brakes are engaged. If the engine is running, then the DTC will indicate a failed relearn. The scan will store the error code in memory. This procedure should not be done while the car is hot or in reverse. In addition, the vehicle should be in neutral and the coolant should be at a safe level.

Once you have a scan tool, you will need to select the CKP system variant relearn procedure. Then, the scan tool will display DTCs related to the crankshaft position variation. During this procedure, the engine will be decelerating, triggering the CKP fuel cut off. In order to clear the DTC, you must make a new copy of the DTC.
