I had a code 28 on my 91 ls400 that the oxygen sensor on the right before the catalytic converter was bad so I replaced it. Right after that the car still stalled and a code 24 came back saying intake air temperature trouble area; open or short in the intake air sensor circuit. Help me please. Where is this sensor located at and can anyone provide a picture of it and advise what I need to do to clear this code? I really need your help because the person who has my car doesn't take anything about this sensor and I've been without the car for a month.

I haven't gotten any replies. No one else has ever had this problem with their lexus?

Hi sorry for the delay.

O2 sensors should be replaced as a pair.

Anyway, Air intake sensor (MAF) is located 4 inches downstream from the air filter. Its in a metal housing with a wire clip on it. Maybe its loose. Its very delicate, dont try to clean it or drop it.

Dont leave your car with someone who does not know what he is doing.

Codes can be cleared with unhooking the battery for some time.

Is this a black box that you're referring to which seats on top of a metal pipe that leads to the air filter?

You car should be able to run with both O2 and MAF disconnected. It would idle rought, but once you give it some throttle, it should be just fine. I think you might have a broken ECU.

Tried disconnecting the 02 sensor and MAF and I still have the same problem.
