Today when I was driving in the highway the rpm was very good according to speed and no skid in the gear. 60+ mph around 2700 rpm. But still has the CEL P0500.

Thanks. I found the exact digram for 2000 Rx 300 from the TIS. It is different than 2001 for wire routings. Like SPD terminal of ECU E9 #22 V-W colour goes to junction connector IJ1 pin # 12 to combination meter C14 pin # 10 (v-W).
So I will check the wirings tomorrow.

Today I found the problems for DTC P0500. It was the SPD terminal of ECU E9 pin # 22 (V-W color) and junction connector IJ1 pin # 12 (V-W) wire was open. So I soldered it now no CEL. I replaced the counter gear old spd sensor with new spd (from sewell lexus) few days before. I drove the truck today and feel like very smooth shifting and my RX get back its young life. Here is the pics of IJ1 connector (behind the right side of glove box. Three connectors together and the top white one). The last pic is the ECU configs according to 2000 RX 300 AWD.

Typically, I find the Lexus connectors and connections to be pretty robust. Can you please add some detail on the break. The green wire seems to have a sharp bend. Any Failure Analysis would be great.
Thanks

Anyone know torque for the sensor bolts? Just got the air filter removed and about to remove and clean the sensors.
Edit: Came off without much resistance, no corrosion on threads. Hand tighten should be sufficient.
As for getting off those sensors, not much luck so far. Able to rotate one about 5 degree each way but can't get enough force to pull straight up.
Edit: One closest t engine was hardest to get off, just wiggled it until it came out. There is a black gasket on the shaft which was probably the sticking point.

Edit: Thinking transmission needs to be hot (expand) for it to go in flush or it was not designed to sit flush (not likely).
