JB4 - SES Light on / Codes - Any help IDing the codes?
Hi guys,
Was recently going up to a friends house and had the SES light come on. It was at night and the lights really fkn annoying so I used the JB4 to clear all the codes to kill the SES light. Later I shut off auto clear and left it light that for a while. No light/no codes.... This past weekend, BAM, fkn light comes back on. I was cruising with little load on he motor at 70mph on the highway in map 2 on 93 octane. These are the codes I found (the top two I've seen before without any dash lights, but the third seems to be what tripped the SES light): - 28A0 No Description Found - 2C90 No Description Found - 2774 No Description Found I did a search for that code and I saw Mike attribute it to something the ECU will regularly throw with the JB4 tune. I'm sorry but I'm not buying that or the ECU magically dropped the code that actually threw the SES light somehow (the light was off the next day). I searched for some kind of index of fault codes the ECU will report but couldn't find anything on the site. Sorry if it's out there. Pls link me to it? |

Mike, reading the code descriptions in the above linked list, isn't the last code (2774) indicative of a boost leak or sticking DV? or is it the opposite? Saying the ECU is freaking out because the MAF is counting more air than the ECU expects?
