Crank Position Relearn

[craig]

hi, the coolant temp has to be above 150 f to run a relearn procedure.the condtions to set a 1336 is when crankshaft variation values are not stored in pcm memory. if you do a relearn and cycle the key and restart vehicle and code comes back check battery power for pcm not key on power. that code is usally a bad pcm. do to this code not being a variation or correlation error its memory error.hope this helps
