Mechanic has spoken with Lexus and toyota dealerships for help. What is mind-boggling here is that the car runs great.
No hesitation, idles smoothly, accelerates fine.

Last option is to remove computer and have a diagnostics run on it.

Hello. Welcome to Just Answer. Please allow me to assist you. Please advise as to what Diagnostic Trouble Code (or codes) you are getting when the vehicle is put on a scan tool. Thanks
Customer: replied 2 years ago.
I don't have the recent code in front of me but it mentioned the timing belt jumped. This us the second time around to receive this code.
Expert:  Toyota Service replied 2 years ago.
If you are getting a cam position correlation code, that usually stems to poor tension setting on the timing belt when it was installed, or, the timing belt was of inferior quality (ier not Lexus parts)
Customer: replied 2 years ago.
Mechanic replaced the belt twice and only buys the best parts. He suggested I sell it but I can't with it having the engine light. Have taken it to several other shops but no luck. What about the computer?
Expert:  Toyota Service replied 2 years ago.
Computer failures are rare, Very rare. Unless somebody jumped the battery backwards, I would not suspect a computer problem. How many miles are on this car?
Customer: replied 2 years ago.
He has called lexus dealers but they have no idea.

Second engine. Over 160K

You might have worn crankshaft thrust bearings. This allows the crankshaft to move back and forth in the cylinder block. When this happens, the crankshaft position sensor does not line up with the unit on the crank that the sensor 'reads'. If this car was in my shop, we would be checking the crankshaft for lateral movement onside the cylinder block.. This condition will give you a crank/cam code even though there in nothing wrong with the car

Getting plenty of codes even though the car runs great. I will take this crankshaft possibility to my guy. Thanks
