Thread: CHeck engine light on

i have a 91 sentra se and my check engine light just came on anybody know how to see what kind of code it is i know hondas you bypass a pin idk for these any body know would really appreciate

Go on sr20dash.com
and search CEL codes, with the b13 you turn a screw on the ECU one way, then another way and it has a built in led that flashes a code. Count the code and use the corresponding code list from said site and see what it is.
