The ECU has recorded the fault. The Honda DTC may be able to reset but in some instances if the ECU has 'tripped' then the only way the fault can be cleared is by replacing it. Had similar when an exhaust valve spiked the ECU on a CBF1000. Replaced the valve and had to swap out the ECU as well. This was all under warranty.
Hi Arthur, Not spoke to dyno jet as the items I used from them are working ok which is the o2 eliminator and power commander.. The fault was there before I put the power commander on the bike as I fitted the yoshi first then tested the bike and the fault appeared so i know the fault has nothing to do with dynojet although they may be able to shed some light on it so worth a try ... thanks...
Dude, the thread is 7 years old and the OP hasn't been active on here for 5 years so don't hold your breath for an answer
And most error code rectifications are beyond the 'average' owners ability to repair. However, as this is O2 and exhaust related, there should be someone here who can advise. Mine would be to trot it down to a dealer!
