Honda Civic 1995 CEL Code: How to Interpret Two Long and Four Short Flashes (Code 24)
I own a 1995 Honda Civic with the Check Engine Light (CEL) illuminated. When I observe the flashing pattern, it shows two long flashes followed by four short ones — which corresponds to code 24. However, I'm unable to find any official reference for this specific code in my research. Most sources list trouble codes from 23 to 30, and I can't locate where code 24 fits. Can anyone confirm if this is a valid OBD-I code for the 1995 Honda Civic? Any guidance on what this might indicate would be greatly appreciated.
I don't work on Hondas, but I know that older models like the 1995 Honda Civic used single-digit trouble codes in their OBD-I system. The pattern you're seeing — two long flashes followed by four short ones — likely represents code 24. According to standard OBD-I flash patterns: a long pause separates each trouble code, and for codes over 9, the first digit is shown with long flashes (tens place) and the second with short flashes (units place). So, two long flashes = '2', four short flashes = '4'. This would indeed be code 24. While official documentation may not list it explicitly, this pattern aligns with how such codes were traditionally displayed on early Honda systems.
