What is a comp? Did you mean pump?Curious thoughts on what wrong, I think it’s the SMT ECU, doing more troubleshooting Monday before buying a comp.
Know of any $$$ reasonable ones out there if so?
I’ve never encountered a wiring issue here; it almost certainly is that the TCU isn’t happy. But, if it’s been sitting and there’s pack rats around, that’s definitely a possibility.The basic meaning of P0860 is that there is no communication between the ECU and the TCU, so for starters you could check the wiring that implements this link.
The BGB says explicitly that if both of these codes occur together, it will result in a fail-safe engine shutdown.
Just don’t let your dealership touch it! The first thing they’ll want to do is replace the TCU, then the GSA, then the HPU and use their expensive SMT fluid, which is just brake fluid @ 12 times the price, lolThanks for the help on this. I work at a toyota dealership, I sell cars, The screen shot is from our tech stream.
The car runs perfect, has CEL on because of these codes?
So, strata up fine, N light on, try to shift into gear and it will sit there a bit, then usually die, fuel or ignition cut it seems.
Then sometimes will shift into either R or 1.
Then sometimes I get the Red Gear light on..
So that’s what I’m dealing with.
I just bought the car from a friend and it is perfect condition and super clean with only 54k miles on it!
I bought it knowing it had “go issues” lol
Yeah, could be a pressure issueHave you watched the accumulator pressure on techstream? It should stay between 40 and 52 bar roughly.
Definitely check the shift stroke position sensor. If there’s fluid on it, that would be the problem.The other code I have is P0919
SHIFT stroke Control system
