1994 LS400 discontinued part search
Can't find a Cam Position Sensor anywhere.
Lexus discontinued it. Lexuspartsnow.com doesn't have it either.
Any advice?
Part # 90919-05010 (Cali Specs)

And for all the "use only dealer OEM parts" people, see this is what I've been talking about for a long time. Soon there will be no OEM for these cars. So some oem attitudes will need adjustment. And if codes for both sensors, I'd be checking the wiring and connectors first. Then looking for a signal from the sensors, and that is hard to do with out the fun stuff like Oscilloscopes.

Is there something else they should be considering as a possible culprit for the acceleration stuttering/bucking and CPS codes? I'm at a loss.

Can you give me a quick "chain of command" so to speak?? Meaning, if it is wires leading up to the CPS's what are they called specifically to that location and where do they draw their power from. Leg bone connected to the hip bone. Hip bone connected to the....

Banshee365, you are always sharp. I can see how you are talented both in mechanical and electrical issues. I admire you reading your useful posts. It is strange for me too to have two sensors go bad simultaneously and need to be replaced. Unlike sensors that have semiconductor circuits inside, LS400/Celsior cam sensors are just made of a core and a coil and seldom fail except the connection issues. The core inside is very well thought of the Curie point and other reliability issues. I have never had any bad experience with those sensors used for Toyota's engines although there were many failed sensors that had semiconductors inside and were made by Mitsubishi used for Nissan, Suzuki, Subaru and some others. I have had many SOS calls from my locals shop owners to examine half dead Mitsubishi's sensors.
I worry about the rebuilt ECU not working well enough. Does it have correct capacitors and has a good capability to remove the ripple for the Vcc? Incorrect capacitors tend to have poor performance of the ripple rejection and the ECU malfunctions. The ripple modulates signals from analogue sensors such as cam position sensors and the processor judges that sensors are not working right. You'd better to check the ripple level first as is shown in the FAQ page.
