Hi - newest member with this problem. I think I've read every page and still have some questions.
Dealership reprogrammed after finding P1FFF and P0AA6 2 weeks ago. I don't know if they did hpcm2
and the BECM, but will find out today. SHVCS came back, and they now want $993 to replace the sensor of course. I'm handy with cars, but I'm no technician, so I have a few choices: 1) thinking about using a defeat plug, and then either buying a vcx nano to clear the SHVCS error or having my local shop do it for me, 2) trying to replace the sensor myself without replacing the coolant tank, and reprogram.
1) Does anyone have the part number for the sensor, and is there a walkthrough to replace?
2) Is the
VCX easy enough to use? If so I'd much rather do this than go to the dealer every time, but has anyone posted instructions on doing this software update?
3) Since I already have the error, are these even my best options?
I've read a few accounts from members going through these steps and still being stumped, or having the defeat in place and the code coming back. I just want to take the most logical steps if someone can advise.
Thank you!
