Well my Volvo s70 radiator was leaking, especially on cold days. They replaced the entire radiator. Than bulb burned out, clock misbehaving - had alternator and battery checked - turned out OK, I was told noise was caused by valve lifters. The whole repair took $734 that I took through <a href="http://ameriloansearch.com/cash-advance-loans/same-day-cash-advance-with-instant-approval.html">same day payday loans</a>. The problem disappeared after they changed oil and used an additive. Alternator bearing is now starting to make a noise. Both shop and I finally agreed we should wait until it gets much worse before spending the big money to fix it.

If you want a wiring diagram, the best place to get access to this information is alldatadiy.com. There you can have access to the same information system that I would use if you brought your vehicle to me for repair. The small annual fee is well worth it if you work on your own car.

Other than that, All I know to tell you is to scan your onboard computer system to see if any of the computer modules are reporting any circuit faults - this can possibly tell you what the wire goes to.

It is also possible that the wire is NOT SUPPOSED to be connected to anything. It may be some type of diagnostic connector or it may be a connector that is built-in to the wiring harness, but is for an option or accessory that your vehicle is not equipped with (this is very common).

It my be you you have an old battery. you need to check the battery and the alternator. Take the battery to a Napa or Orileys and they can check it for free. If the battery is good, your charding system may not be charging.
It could also be your starter is worn and requires extra power to turn the engine over. Start with the battery check

Car no start problem is sometimes very difficult to confirm. You try all the possible things, but still you get no fault and problem is still the same.--------
In that case, you need to check few things individually.
Check the spark,the battery,the crank, the fuel and other most possible parts. Click this link below for more details:-- http://howtobyme.blogspot.com/2011/10/car-troubleshooting-tips.html

  • Well, if it starts with a jump and runs all day with no problem then that would indicate that the alternator is doing it's job of charging at least. Does the car function normally all day after a jump start? The problem could very well be the battery needs replaced or something is draining the battery overnight and the battery is fine.

  • I would pull the battery and have it tested at your local major parts store. Or better yet if drive-able, drive it the vehicle to the parts store so they can load test it.

  • If it is good then you want to look for a wiring issue. If it tests bad then replace the battery.


  • Hope this helps.

Trouble code P0722 means: Transmission Speed Signal Missing
I'm not a Volvo kind of guy. Just letting you know what the trouble code means.

This was a common problem on 99's and up. It is usually a permanent fault of the throttle body. The fix can only be done at a dealer as they have to download software to the unit itself. Good luck.

Most of the time this requires a replacement of the unit itself. This is a very common problem and can be confirmed by a diagnosis at the dealer. Installation of a new one requires a software download and must be done at a Volvo shop.
