Is there a crank sensor relearn on a 96?

[milky9788]

I just got my reflashed computer (totally different serial number from my original one) and I keep getting P1336 ckp sensor variation not learned...my truck is a 96 C1500 5.7L/Auto

Anyone???...and also once it gets warmed up (operating temp.) it stalls out and dies but it runs fine cold

By reflash do you mean it was modified by a performance shop?

Yeah sorry I forgot to mention that...I ordered it from nelson performance.

I'd call them up.

I'd call them up.

Actually I literally just email'd them

yeah, thats a relearn code. you need a CASE relearn...a shop or someone with a TECH2 should be able to do it. but see what nelson has to say.

Yep that's what they said...would needing a relearn cause my truck to run horrible when at operating temp?

its probably going into some kind of limp mode, it doesn't know what position the crank is in and therefore its having issues trying to control the spark and injection, etc, sometimes they run fine without doing a CASE relearn, sometimes they don't...it shouldn't take a shop more than like 5-10 minutes to do it. just make sure they're ONLY doing a CASE relearn, not a reflash, the tech2 can also reflash a PCM back to stock, you don't want that since you spent your money on a tune for it.

Awesome thanks for the information man...and I ended up sticking my stock pcm back in for the time being.
