What​ happen.

Engine.light Blinking​ any​one​ pls.tell.me
Thank​s

Hey, Tory, I don't have my manual handy at the moment but in automotive circles that indicates a condition that could harm the catalytic converter. Usually a misfire. If no one else chimes in I will be able to post chapter and verse later....

Hi Tory, your oxigen sensor heater is open circuit, code 23;

Have a look if the wiring is damaged on the oxigen sensor and the connector is in place.


PCM codes and their meaning
PCM DTCs:

1 - manifold absolute pressure (MAP) sensor (1-1=low voltage, 1-2=high voltage)
7 - engine coolant temperature (ECT) sensor (7-1=low voltage, 7-2=high voltage)
8 - throttle position (TP) sensor (8-1=low voltage, 8-2=high voltage)
9 - intake air temperature (IAT) sensor (9-1=low voltage, 9-2=high voltage)
11 - vehicle speed (VS) sensor (11-1=VS malfunction, intermittent connection etc)
12 - #1 (left) fuel injector (12-1=FI malfunction, intermittent connection etc)
13 - #2 (right) fuel injector (13-1=FI malfunction, intermittent connection etc)
21 - oxygen (O2) sensor (21-1=O2S malfunction, intermittent connection etc)
23 - oxygen (O2) heater (23-1=O2 heater malfunction, intermittent connection etc)
29 - IACV (idle air control valve (29-1=IACV malfunction, intermittent connection etc)
54 - BA (bank angle) sensor (54-1=low voltage, 54-2=high voltage)
86 - serial communications (PCM to cluster) (86-1=communications error, bad power to cluster)

If the bike drives normally it may be a good time to install an o2 sensor eliminator, have a look at these links;

Tory Note that the eliminator will not work on 2017 models, only on earlier ones.

Personally i have installed a 330 ohm resistor and it works fine on my 2010 cb1100.

Great post Max, and saved me some work I just got the manual out and then saw your post.

My prediction. He put on an aftermarket exhaust and no O2 sensor. I could be wrong...

Thank​s​ all.of.you problem​ so​love​ by​ O2cencer

Max, excellent/professional job!!

So 2 blinks = 2 and three blinks = 3
code is 23...cool, learned something
new about my bike today... I think in the
recesses of my mind I know blinks are
code, but I never seem to remember in the
moment and I just think “huh?, its blinking!”

Very helpful information, max, and even better now I know how you arrived at 23.

Is there a difference between 23 and 23-1. If so, how is it signalled?

Tory glad it is fixed, what was the repair? we would like to know

Cormanus i was hoping houtman would chime in and cleared this up because the1 and 2 stands for two different faults.
i guess it is another short flash after the 23 code but i have not seen any example of this, i wondered the same thing.

IIRC the sub codes don’t flash. Need a code reader for those. I’ll check the manual in a while to be sure. Its too early now. Need coffee
