How to relearn the crankshaft variation relearned?
How to relearn the crankshaft variation relearned?
NOTE: If the Crankshaft Variation Relearn is not accessible through your scanner (some truck applications 1998 & later), perform the relearn in the following manner: 1. Turn off all of the accessories.
How to do a crank Relearn on a computer?
To perform the relearn, proceed as follows: Connect a scanner to make sure there are no trouble codes stored in the computer’s memory. If there is any power train trouble code other than P1336 (Crankshaft Position Variation not learned), the computer will disable the relearn function until the problem that caused the code has been eliminated.
Why does my car not start after replacing the crankshaft position sensor?
I changed out the crankshaft position sensor on my car because it was losing power while driving and the code on an AutoZone scanner said crankshaft position sensor. After replaced with a new one, car had a rougher start, no loss of power but now, two days later, it won’t start at all.
How to change the crankshaft position of a car?

(70 degrees C.) 3. Turn the engine off for at least 10 seconds. 4. Select the crankshaft position variation learn procedure (CASE Learn)on your scanner. 5.
When to do a crankshaft variation relearn?
Crankshaft Variation Relearn Procedure must be performed if: • ECC was reprogrammed. • Crankshaft position sensor has been replaced. • ECC has been replaced. Follow the relearn procedure outlined below: 1. Install scan tool on Data Link Connector (DLC) located under the dash. Apply parking brake and block wheels. Insure hood is closed. 2.
What happens when you replace the crankshaft sensor?
Q: Replaced crankshaft sensor and now car won’t start. Even tried putting old one back and still won’t start. No problem starting bef Was told my crankshaft sensor needed replacing.

Why is the position of the crankshaft so important?
The speed and position of the crankshaft are two key parameters that the car’s computer uses for engine management calculations. So, you may understand how important it is for the sensor to work without any glitch. Let’s learn about some crankshaft position sensor failure symptoms so that you can take action when there’s a problem.
