Lsx 454 efi - p0315 hi guys
i got this code when i was scanning the ECU ,, this car is fresh made and this is the first starting , i heard that there is a procedure for crank sensor relearning to make it work ,, so any one has background about that , i have HP tuner if it is required to use
for your advises ,,
thanx

Crank relearn can be tricky to get it to go. Took me multiple
tries to get the RPM held just so, and previously I have had
some sensor faults inhibit it (one that the scan tool would
not pull up, but Tech II did at the dealership). All this code
really means is that misfire detection is going to be whack
(probably just not functional). Hurts nothing about running.
Scan tools I have seen work, and not work, and work again,
and not work, for running this test across software version.
But the tools have some documentation on "crank relearn
procedure" and I'd bet this section would yield some stuff
too from a keyword search.
