View Full Version : P12 crank sensor relearn unavailable?

February 19th, 2016, 10:26 AM
I'm trying to do a crank relearn on an 05 Chevy Colorado with the i5 engine. But there is no p12 controller. Has anyone find a way to perform this?

Seems P12 support is gone in EFILive.
I don't remember that it ever had the option to do crank relearn, EFILive will remember crank position.
I need to do a full flash on a P12 but last time I tried it was a nightmare.
Hate to say it but you might have to find someone with HPtuner.

Try selecting LS1B for doing crank relearn.

Use LS1B 99-07 as the controller, the only time you need to do a Crank relearn is when you swap in a different PCM. The CKP data is stored in non-violate and never overwritten even with a full-flash.
