O2 sensor issue
« on: 06 September, 2018, 10:23:28 AM »
Hello everyone,

İ have a strange issue, mil blinks 23 times and it points o2 sensor heater problem as might be expected. I checked all steps in service manual everything seems OK.  So i bought another secondhand O2 sensor and results were same. Thought that Honda dealer would solve my problem, they checked all wirings and measure it but couldn't find anything and mil is still blinking. Does anyone have any idea ?

Did you and the Honda dealer really follow ALL steps in the workshop manual, pages 6-48 & 6-49?....

4. O2 Sensor Heater Short Circuit Inspection
Check for continuity between the test harness
terminals and ground.

Connection: B2 – Ground

Is there continuity?

YES – Short circuit in the Black/green wire
NO – Replace the ECM with a known good
one, and recheck; refer to Key Registration
Procedures (page 22-6)
