is a 2000 sir engine b16a2 obd2a or obd2b
obd stands for On Board Diagnostic, for ecu's only.
engine don't have obd classifications.
acutally half way through 99 on all model civics except the SI was a or b just a refrence not important
not true. 98 civic ex's are obd2b
are you sure about that? i could have sworn the ECU i used to pass smog was a 98 ex, which plugged into my 96 harness (obd2a).
Yeah i thought it was a OBD2a
Stupid question. What is the difference between obd2a and obd2b? Is obd2a the same thing as obd2 basic while obd2b is obd2 advanced?
the common differnece between them is the plug pattern
Separate names with a comma.
