    Nope, they are un-related.
    code 34 is Det sensor error. (to cure this, bypass the det sensor by using a 1 Mega Ohm, 1/4 or 1/2 watt resister to plug either end into the ECU side of the Det sensor connector).

    Regarding the dash warning light, is it the "check engine" light?
    Also, if this is the warning light, did you say you were also still able to connect your ECUTalk to the ECU and give results?

    ...if answer is YES to both the above questions, firstly check the fuse in your engine bay fuse box (passenger side behind headlight), for the "Engine Cont" fuse. See if thats blown. If so, replace.

    This is a possible scenario for these symptoms. If you can rule these out, please post up to let us know to keep diagnosing.

    ok, in this case, it's just a connectivity issue.

    I'd firstly go to your ECU and check the loom connector to it, make sure it's seated properly and evenly. Either way, unscrew and unplug it, check the contact are clean and refit.
    Do you have a chipped ECU or Nistune fitted? If so, crack open the ECU casing while you're there and make sure the Eprom / daughter board is seated properly and check for other possible corrosion or dry joints on your PCB's.

    Other than that, do a visual over the loom that goes through the engine bay, particularly towards your PTU, as it sounds like an intermittant problem that is due to a bad connection through a connector or possible cracked wiring.
