Question about 2000 Volvo S40
My s40 stalls when stopping at a top sign. it seems to lessen with the AC off but still dies regularily. I have several check engine codes that come and go. P0401, C3200, P2601, P0601, P0100 and P0301. I have checked for vacuum leaks using starting fluid but haven't found any yet. Any help is appreciated.
You have lots of codes
Have you not used Google to look them up?
I doubt all the codes are failed system issues
I suggest to anyone coming to this site, to use the
services of a repair shop or buy & learn how to use professional
scan tool software,I fail to see how you can diagnose anything

Testimonial: "I've attempted to look them up but unfortunately the codes are not consistent. After clearing the problem continues but new codes appear. to further confuse the issue google results in inconsistent results. the codes I can identify seem to point to each other and each suggests if mis-diagnosed the other is the likely issue. I'm just trying to avoid replacing a lot of components unnecessarily."

The best thing is to go to your local Volvo maintenance shop or Volvo experts to find out whats the problem..usually the coomon ones I think is the programs inside its ECU unit..you try this..ask the volvo experts to reset the ECU and lets see..if problem arise then it is no doubt you might need the sensor..hope this help..

I have a 2000 Volvo S70 as well with the same code. Do you ever have trouble starting your car? I did and that's why I took it to the dealer. Appartently it's the code for the ignition immobilizer system in your car (part of the security system). Specifically, a part call the antenna ring. The antenna ring is the outer portion of your ignition switch on the steering column - the part that lights up and has the following printed on it: 0 - I - II - III. This part is actually a sensor that transmits the code stored in the microchip inside of your key. When this part goes bad it fails to transmit the correct key code to the computer, and cuts the fuel to the engine.
The dealer wanted to charge me $550 for a new antenna ring, two new keys, and software to program the car's computer with the new key codes. I purchased the antenna ring online for $50 and did it myself in 15 minutes - so easy. They claim that you can't replace the antenna ring without new software - lie! You only need the software if you are replacing the keys.
Car is running great.
