Back on topic! I did a search on 2006 S2000 so If it's older let me know. 06 is the first for DBW.
The testing for this problem requires a Honda scan tool.
2138 is the APP Sensor A/B (TP Sensor D/E) Incorrect Voltage Correlation .
P2122: APP Sensor A (TP Sensor D) Circuit Low Voltage
The part should ball park around 150 bucks if it needs to be replaced. minus labor.
37971PZX003
Testing requires jumping pins and measuring data for % and voltage on a Honda specific scan tool. I imagine if you have a $5000+ dollar tool like the new Snap on scanner or a gynesis you could pull these numbers required. Starting point for diag is trying to find a short in the wires, not replacing the APP.

I never really understood the need for DBW. Why was this change a necessity for honda?

What year is your car? 2006 + cars are drive by wire. That mean that the TB and pedal are not physically connected. There is a Sensor in the pedal and a motor/sensor in the TB. So your code is telling me (Throttle/Pedal position sensor) that your pedal sensor is suspect.
thank you all for the inputs!

I know the last post is over 6 years old. Thanks for the post people sure made my day. I replaced my TPS on my 2006 DBW S2000 and its fixed. But not before I replaced the primary and secondary O2 sensors, fuel pump, plugs and coil packs. Just replace the TPS first before you do all the other items. Replacing the TPS is straight forward and takes 30 minutes tops. 
But you can consider the effort as preventive maintenance which is always good.

Accelerator Position Sensor
Which one did you replace? You say you replaced the TPS but that is integrated into the Throttle Body and cannot be replaced on its own.

The throttle position sensor on the drivers side just behind the shock tower. Not the throttle body sensor. The throttle cable from the petal goes into the throttle position sensor. Hope this helps you man.

I have this problem too man, haven't replaced the accelerator pedal sensor yet though. I also need to replace the temperature sensor TS5615-NP
