1.....1.1.1.....1.1.1........1........1.7.2.....1. 7.3.....172.....173
the first flash is nothing followed by the KOEO codes(codes repeat once)
111= system pass
1= seperator followed by the continuous codes
172 = HEGO show system always lean
173 = HEGO show system always rich
O2 sensor seem like the logical place to start. There are ways to test the O2 sensor for function but I have never tried it. Hope it helped
