2004 Silverado TPS 0 volts...
I picked up a 2004 Silverado a while back and have been slowly getting it sorted out... It is a 260k mile farm truck, so its been neglected for a while. I have too many spare Silverado parts so I figured I should start learning this HPtuners stuff in case I decide to try any swap/cam stuff in the future. So, I have no idea what I'm doing yet and this stock 4.8 is my learning platform...
That said, I've learned quite a bit from reading on here but results for "0v TPS" searches haven't helped as much as usual. I took the truck to town this morning, so the attached log is cold start, warm up, normal drive... no WOT, etc.
(Besides the corrections on what I should be logging and units of measure... currently shotgun blast method.) My question is, where should I look next? So far I have gotten rid of all codes successfully, still sluggish/gutlless. but I did have P0172 and p0175 pop on the drive prior to this log that is still illuminated.
When I first got this MPVI3, I was replacing a lot of parts so I didn't pay much attention to the new TPS sensor not correcting the 0v, I assumed I was using the scanner/log wrong. But I'm going to fix the exhaust this weekend (passenger manifold at firewall, like every other GM on the road..) and figured if I'm going to be crammed in there cussing anyway, could bad grounds somewhere be the TPS voltage problem?
Been able to keep my own stuff on the road for years, just been a holdout on joining the technology side... I'm going to need help to get an understanding of this software...
