CODE: C0003 TCS Control Channel "B" Valve 1?

Recommended Posts

Hello, got a 1996 850R Estate (wagon) 170,000 miles and have a check engine light on.

I got the codes ran : P0172 (vacuum line/hose leak) and C0003 TCS Control Channel "B" Valve 1 (subfault).

What is this C0003 code? I mean, any thoughts what this means?

I appreciate any and all help as I am trying to get this squared away.

I used the search and advanced search tool but came up with nada and can't find any info on the web.

I'd guess it has to do with traction control? TCS is what the traction control switch I believe.

Hey ODN, yes I believe that has something to do with it but, am curious what needs to be done.

Well I don't know how the old TCS system worked but the newer one work by cutting fuel which would have valves in the system, also possible it works off the ABS, maybe someone who knows can chime in

Don't know why there is an issue with responding.  Anyhow, I am guessing that since finding any real info on this code then it must not be a serious issue or is piggy-backing off of the P0172 code.

Anyhow, I am guessing that since finding any real info on this code then it must not be a serious issue or is piggy-backing off of the P0172 code. Fixed the responding issue.

      Car came with its drive shaft pre-removed but included. 12 total wheels and tires, a brand new set of R mats in the volvo box, and a stack of service receipts totaling 26,000 CAD.

      Purchased at 121,000 miles currently 152k on everything.




      March 2014 - Acquired many nice parts through the winter. Met Bmac and got everything installed and then had Steve tune it the same evening. Long day but everything has held together like new since then.
       
      Snabb kit was a oh yeah! to install, lower pipe need to sit just right to make it all work.

       
       
      18" of space was nice but we almost needed more.

      Clamshell was not surprisingly rusted closed.

      ugly ugly welds but it went in perfectly. Did require cutting the old downpipe to clear the angle gear.



      Bens BIG turbo


      Manifold and turbo and exhaust removed.


      Nice new nuts and reused the washers.


      Huge difference in design.


      Sway bars are such a nice improvement on this car
      Reused a front bar from VS, rear can be had new without buying the set (just ask)


      Practice Safe Turboing

      Found a guide form what what i can't believe is 10 years ago. Thankfully the pictures are still up http://v70r.com/forums/topic/1667-ohlins-strutspring-install/
      Had to get a offset box wrench but it was really the only tool for the job.

      Not sure if VS works this way but Saving this space for suspension and brakes when they go on.

      T-5R Wagon (1995), black, automatic transmission, mostly original with a few moderate suspension upgrades. Approximately 175k, with careful and regular service. This was a California car for most of its life, and is (from best estimates) one of fewer than 100 still on the road in the U.S. It comes with: IPD 3" cat-back exhaust; 4 steelies with snow tires mounted; trailer hitch; original parts no longer installed; and your choice of body panels and parts from a 1995 black 850 NA wagon (parts car). I am a motivated seller and will take $3,000, for the next two weeks. Contact me and I'll answer all questions, to the best of my knowledge, and send any additional pictures that you may want. The car can be seen in Delaware, near I-95.

      Hey guys, 
      Recently my car has been shooting me with "reduced engine performance" and "engine system service required" Error codes. Yesterday I tried to replace the throttle body on the car thinking that was the problem. Once I tried driving it the acceleration was still the same very slow, and didn't go past 60 mph. So now I'm taking the other throttle body back since that obviously wasn't the problem. I'm wondering if its and issue with the turbo instead or even the air intake. Has anyone else had these issues? Please let me know.

      Well 
      after many good years she finally became a cost of operations issue. 
      Looks like we lost compression in one cylinder. So it’s time to part ways. 
      Odo is broken but estimated over 450k miles. 
      Interior is still good the leather is anyway  
      so here’s the deal:
      2 sets of tires on rims  barely half a season each, snows and a set of uhps 225 45 17
      est turbo back
      ARD green tune, obdii compliant, rear O2 delete 
      16t angled flange
      IPD RIP kit with one-off red silicone charge hoses 
      AC Delco boost solenoid  
      BMAC replaced the head completely with a unit from that place in Clearwater Florida 
      lower end rebuilt 
      brakes are serviced with 220 brackets up front 
      Ignition stuff done aboot 18 months ago
      just flushed and filled tranny, radiator and brakes  last year 
      shocks/springs done 2 yrs ago with Sachs
      many of the bushings and engine mounts were done
      Look, the car needs work to get engine working 100%  the car has its normal drips leaks and creaks  but it’s a solid vehicle
      Bottom line is there are a lot of good useable parts on this car, the tires and wheels alone are $1000. It would make a great project or just a repair for a daily beater. It goes like a raped ape when it’s right.  
      I’m asking $2250 as is. But price is flexible 
      the car is located in Burghill Ohio at my sons house. That’s eastern part of the state almost in PA, aboot 1 1/2 HRs from Pittsburgh.
      Make an offer contact me through this site or contact Bmac if you wanna check me out.
