I've got a 2001 V70 non turbo.
It won't start, and the OBD2 scanner says intake air temperature sensor. I figured no problem, I'll just swap it out.

Problem is I can't find it. Everybother car I've ever had, it's right up front in the intake, between the air box and the engine. I went to the dealership hoping they could she'd shed some light on the subject, and they tell me that there is no IAT sensor listed for that car, and Volvo doesn't use obd2 codes.

So number 1. P0113 code in a Volvo means what, since they don't use OBD2 standards.

Number 2. What else should I be looking for?

 

there is an air intake temp sensor - google part number 9209888 - some of the dealer parts web sites will have diagrams for location but I'd start by looking on the air filter box.

other than that I'd suspect it could be the MAF or possibly the ECT sensor.

 

I got a 2001 s40 and it wont start. It comes back with the code po113 air intake temperature sensor and i don't know where it is

 

That's probably not what is causing your car to not start. Usually when that code is stored the ECM uses a substitute valid value - One that the car used the last time it ran - to make sure the car still starts and runs. Don't replace by code, it gets expensive and frustrating fixing cars that way. Try to find the real problem first - before replacing parts you think might be bad. Compression, fuel pressure, fuel delivery and quality, spark, etc would be the places to start looking first.

But to answer your question, It's in the outlet of the inter cooler and it look like this.
