Hi there my 2010 civic was doing the same problem I replaced the ECM still had the same results as you I work in the Nissan dealership shop next to a Honda shop they have never seen this code in a Honda so we started eliminating things checking all the ground wires then pull the spark plugs and found that my spark plugs had burnt down to twice the gap that they was supposed to be I replaced the plugs fix the problem must have been putting a lot of strain on the coils causing the e c u to go into limp mode so your problem is probably your spark plugs are good be your coil on plugs
