on the front is it the tire or something

One day it was driving normal, the next day it started running rough. Mechanic said it wasn't sending any signal to the computer. It's basically brain dead! How did this happen? And can it b fixed fairly inexpensive?

SRS airbag service urgent - what does that mean. Anti-skid service required, what does that mean.

car still ran though was slow from a standing start to pick up speed again. would pick up speed. when I stopped and shut car off then restarted, all worked fine, however check engine is still on

2004 volvo 260 with 151k miles

hi i have a vovlo s60 diesel engine and every time i want to change gears only wennstrom starting off the čar fumes and jesrks off
diagonisis shows
0083 vehicle speed sensor signál too low
5310 communication problém with gearbox control module
6805 boost pressure control , faulty coconfiguration
throttle solenoid signál mission
0113 pressure solenoid missing

I have a 2004 S60 with 135k on it and I have maintained it regularly, using independent shops in the Denver Area for large jobs requiring special tools and have also made several electrical system repairs to it myself.
This fall after changing the cabin air filter the climate system has a malfunction and will come on in the HOT defrost mode only. When the car is first powered up the blower will be full blast in the front defrost mode. I can turn the blower down but it still blows hot air through the defrost ports below the front windshield. It gets very hot in the cabin, so I am thankful it is winter.
I had lunch with a client whom owns a repair shop and he put a scan tool on it and it generated the following codes: CCM-000C Right Temperature Damper Motor, Signal too low, CCM-000F Damper Motor, Defroster, Signal too low.
We decided to re-set the system using the scan tool and following the re-set procedures then the system generated the following codes: CCM-000C Right Temperature Damper Motor, Fault, CCM-000F Damper Motor, Defroster, Fault.
So I could surely throw parts at this and replace the Damper Motors, but am curious if anyone has dealt with this issue and can comment if changing the motors solved the issue, or if there is another component that should be checked.

lid is two piece. Mine is the plastic part with license plate holder

New tires an alignment/balance done. Tie Rods will soon need to be replaced. What else would cause a low humming whoop-whoop at low speeds... an a vibrations at 60 to 70 mph?
