Replaced a computer and the SC400 runs again, but... Prior to the computer replacement there was a Code 24 on this car and now that the computer is replaced, the Code 24 remains. From what I read, the car shouldn't be running great, it should have a rough idle, but right now the car does run great, purrs like a kitten. Moderately tempted to just let it go, but I don't like codes on a car.
Some questions:
Are the MAF and Intake Air Temp all in the same part and wrapped up together in the black plastic part below? After reading I am 99% sure they are, but I have a very short history with Lexus cars and am looking for some confirmation.
Assuming these are in the same part, and assuming this part can't be fixed, any recommendations for the replacement? I see MAF's for this car running from $50 to like $800 (which appear to include the aluminum housing?). Granted an original Fuji Electronics parts is likely best, but wondering if there are any aftermarket parts that people have had good or bad luck with.

Just the MAF, not the aluminum housing
Yes, that's why there are 5 wires on the MAF plug. I just left the harness side plug when I eliminated the MAF and plugged the new intake air temp sensor into the correct two wires going back to the ecu when I replaced the factory ecu with the standalone MS3. Can't recall the color code of the two wires, but could look if you needed that.
