Okay I really could use some help here, 04 rx330 throwing the p0500 code. I replaced both of the input and output sensors, even thought that the output sensor was maybe a faulty one( got off Amazon ) so I went down to auto part store and bought another on. Problem is, so last night I put in the output sensor, obviously battery was unplugged, installed the sensor re connected the battery, tried the transmission module reset sequence.. and the car did great until I turned it back off and back on and immediately the vsc came back on with the CEL. Oh an the transmission is literally brand new, maybe 5k on it. It shifts like a dream when it does, but what happens is if that light is on the vehicle at about any speed will randomly feel like it just drops out of gear and for about 5 to 10 seconds the gas pedal just revs the rpms. Then it’ll kick back on and go until it does it again. Since replacing the two solenoids the problem has got substantially better but still there. Also I’ve taken it to a shop and had them clear the codes with a reader. I don’t have one, unfortunately. Still came right back on. I’m wondering what you fellas think it could be, it’s my wife’s car and I’m starting to think MAYBE it’s a short somewhere maybe but any help or suggestions would be great

 

I wonder if you need to wait more cycles for light to disappear on its own. It took my RX400H many cycles to accept new MAF sensor and for the engine light to stop coming on.
