OBD gives P0113 reading (Intake Air Temp too high) Sign In

1998 Isuzu Hombre (re-badged Chevy S10)
engine is 2.2L four-cylinder, five-speed manual, no air, PS, PB.
About 138,000 miles. Front end rebuilt and brakes done.

My OBD popped a P 0113 today. I replaced the Intake Air Temp sensor and I still get the reading. With the sensor replaced, am I allowed to clear the fault manually? I have to get it smogged in the next month and I want to get it up to speed.

I'm also getting a P 0420 (Catalyst efficiency below threshold) and I'm wondering, should i replace the catalytic converter pre-emptively or let the smog guy tell me?

Thanks in advance for any information you can offer.

Why go to an inspection that you know you are going to fail. You will need time for the monitors to reset after the cat is replaced so the sooner the better.

As for the IAT code, the problem can be anywhere in the circuit and the code does not mean "change the sensor". It means find out why the code set. They have a lot of problems with the wiring and plug at the sensor. you can buy a new pigtail and splice the wires to it. just make sure you get the wires in the right position because the wires will be all white on the new pigtail.

I'm not taking it to an inspection til I have this stuff resolved. I have a cat ordered, but it's got to be CA legal so it's very expensive. As old as the truck is (14 years old) I figured a new sensor was $15 well spent. Besides, swapping out the the sensor is something *I* can do. I can change out the cat, too, but I'm not looking forward to that. At least one night of being soaked down with WD40 is in the future of all those nuts and bolts.

I have to order the gaskets for the cat. Ugh.

Be glad in CA that a tough job involves penetrating oil. Your truck in WI doesn't come apart without one of two tools. Either a cutting torch or the finger of god.

Cutting torch is a little easier to come by.
