On my 92 sc400...i threw code 24 and 25(24-Intake Air Temperature Sensor signal.
25-Air-Fuel Ratio Lean. ). 25 is running lean and 24 is air intake temperature sensor. Anyone know what code 24 can be caused? Where is the sensor and the cost and labor to repair this thing. For my code 25 I assume it is the primary o2's. ANy suggestions and/or experiences woudl be great guys! thanks

 

nobody knows what this is?

 

Air intake temp sensor is located inside the mass air flow, which is the same unit. Lexus used the same sensor measure both air volume and air temperature.

Code 25 means one of your main O2 goes bad. You have 4 O2 sensors on your car. Two main sensors are located on the exhaust manifold and two sub sensors located on the exhaust pipe right after the catalyst convertor. If one of the main sensor goes bad another will follow. I recommend to replace both of them at the same time.

 

code 25 makes sure u read the fine print if u get a hold of 1 from lexus. cuz 25 i belive is the sub o2 on bank 1. ive made that mistake once.

 

Most people say code 25 is from upstream airflow, thus making it the primary o2 sensors that are bad. Any comments anyone on this statement? thanks

 

ill check tomarrow on tis. for now give me the vehicle info. ie
year make model

 

ok i looed at tis and
