Check engine light on

Thanks, I had forgot about the ob1. You have to jump the last two cavities on the right of the plug. You can bend a paperclip in the u position and jump those two cavities. After that turn the key on, and count the blinks. The 1st code will b code 12 that’s letting you know that the unit is active and then after that. The blinks will be like it will blink check engine pause check engine and then like check engine maybe 4 blinks that's code 14 one blinks = 1-4 blinks =4 so and so on.
