I have HP Tuners but I am not a tuner by any means. I use it mainly to remove basic stuff from swaps etc.
My wife's avalanche is bone stock, 2007 5.3.
It started hesitating on take off so I pulled codes.
P0016
P0121
P0449
P0455
449 and 455 are irrelevant
The truck is drive by wire so I replaced the gas pedal, it was in stock at LAPS so I figured common issue. Cleared codes, wife drove it around. Says its better but still hesitates.
Pulled codes again this time only P0016 is present.
She has also complained of a rattle that I have not heard myself.
So looking up P0016 it states that it is P0016 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
One of the issues it says could be a slight rattle indicating a damaged tone ring which would explain what she was referring to.
So can you use HP Tuners to pinpoint where it is failing. She is supposed to go on a trip tomorrow and she told me all about this last minute (of course).
Any help appreciated.
