Q: Check engine is on. Diagnostic trouble is in #24. Intake air temp sensor signal. on 1990 Lexus LS400

How much will it cost me? It says either not properly installed or needs replacement. Who can I trust for this?
Is 2nd hand/pulled out parts will do?

no, new only only after the issue is determined. the sensor needs to be checked, power to it verified and signal return verified before you can say what the actual issue is.

Thank you Roy. I will just hope that this sensor needs not replacement. Somebody said that this (new)sensor cost more than a $1,000.00?
