Here are a few...

0 - bank angle sensor, ECM, PGM-FI fuse
1 - MAP sensor
2 - MAP sensor vacuum hoses, or sensor itself
7 - ECT sensor poorly connected or open circuit
8 - TP sensor, TP sensor wiring
9 - IAT sensor connection, or open wire
10 - Baro sensor, or connection, or wiring
11 - Vehicle speed sensor, or connection or wiring
12 - #1 injector connection, or faulty injector
13 - #2 injectior connection or faulty injector
14 - #1 connection or open/shorted circuit
15 - #2 connection or open/shorted circuit
18 - Cam pulse sensor, connection or loose sensor
19 - Ignition pulse sensor, connection or loose sensor
20 - faulty E-PROM in ECM.

Have a look here for all of the codes - CLICK

From looking at the pictures Red Rider posted on that other thread, it seems your O2 sensor has gone kaaput (Code 23 - Two long, three short)

no, according to the manual, it will operate normally. Are you sure its code 23?

The procedure is this;

unplug the O2 sensor connector and check for bad connections/corrosion.


plug in --> if 23 blinks, measure resistance across 4P connector

Use the two WHITE terminals, it should read 10-40 Ohms, else, faulty sensor.

Hope this helps.

PA should be a 49-state bike which doesn't have an O2 sensor (and a different ECU that doesn't look for the missing O2 sensor). Cali bikes have the SC441 VIN code.
Could it be a 10 and 13 code?
Is the gap between the two long flashes the same length as that between the long and short flashes or is it longer?

if the first gap between the two long blinks is longer than the one between the second long and three shorts, its two different codes. As bladeracer said, unless you have a california model, you dont have an O2 sensor in the exhaust.

1 blink = MAP sensor problem

1 long, 3 short = code 13 = problem with injector #2
