P1810 DTC...help please
The past few times I drove the car, the converter lockup has been acting all funny. I would lock, unlock, lock, unlock, etc and then eventually just stay unlocked.
Last night my SES light came on and I got a P1810
-DTC P1810
TFP Valve Position Switch Circuit
I don't know where this thing is located or how hard it is to change. Can anyone please provide some insight? Thanks!
