    Crankshaft relearn 2007 Tahoe help

    Anyone no the proper procedure to relearn crankshaft sensor? Tried the relearn on hptuner but reving rpms to fuel cutoff doesn't seem to be working. I'm new to this so if there is any other info I should provide please let me know. Thx in advance!

    u can do that or in hook the battery for 20 to 30 min to minimize draw and sleeping moduels then hook it back up and rev the engine and let off, the next few revs should bring the engine back to the rev limiter in the safe zone hope that helps I use our snapon modis for all relearns at our shop
