Kindly I am open for suggestions...

The car was parked for a long time about 2 months, I noticed front wheel was seized (I think caliper) and I just got rid of p2138 by installing a new TB and a New DBW....

I bought new clippers (it will take weeks) but now I have this error. 27-01 and 83-01



I am in Dubai and supplies are very limited for this 2007 s2k.

What should my next move be?
A speed sensor, drive by wire issue, battery voltage?

Triangle and vsa on but no check engine light

 

I noticed battery voltage is weak, so I am putting a new bAttery

 

I think 83-01 is a code that is set when ABS is disabled due to another system issue. You mention that a front wheel/brake seems seized due to the caliper, which I would think is possibly related to whatever is causing that issue. Sounds like there is a story behind his car for sure with all the codes you mention.

Thread where someone fixed their 27-01 issue
FIXED - VSA code 27-1 - Steering Angle Sensor - S2KI Honda S2000 Forums

 

The problems are endless in this car...

First the 2138
Then I noticed cel bulb was pulled out of the screen (which i reinstalled, I basically took the seat belt bulb in its place)

Then to discover cat is pure empty (which I installed extender for the o2 sensor) to get rid of the heat o2 cel...

Then the vsa + triangle + cel + p2138, I replaced the TB + dbw

I rested the ecu with hondata pro flash and was just about to update it with the early 5.5k rpm vtec performance thing...

Now the sized caliper and the codes I mentioned....

I did put a new clutch though and a flywheel... Mhm... Starting to get tired
