Crank Position DTC Code

Hey Guys

I want some help in removing this DTC code about the crank position learn code..

I have flashed my ECU and i just tuned my car it has a SC on it... But it seems that the code is not getting away, its always there, and really giving me a headache, check engine light keeps on coming on...

Any way to put it on learn mode when the ECU is tuned, and it is tuned by HPTuners...

Any help will be really appreciated...

Help your fellow here....

I'm assuming you are getting the code P0315? For crank variation not learned. You need to have someone with a Tech2 do the relearn for you. A dealership will do it for you to.

Well thanks guys, i will try again with the HPTuners, i have tried to do it with the tech2 it did not work i dont know why was it... The tech2 did not accept doing the crank position learn...

The ECM might see false engine misfires without doing the relearn. Make sure the Tech2 you are using has been updated and that you build the vehicle properly in the Tech2.

My tech2 is updated and its the same tool that i used to flash my stock program in before the tune, but after the tune it did not want to make the relearn for it...

Is there anyway that it could be prevented because the car is tuned by HPTuners, and by the way the tuner did not lock the tune in the car....

Thanks alot
