throwing p1312, but flashed? I have AP1 flashed with stage 2 now, and driving home CEL came on. Got home and the AP say 1312. uh, help? I thought that sensor was 'turned off' on a stage 2 map?
What does a 1312 mean? A quick google search shows that one of your injectors is fubared. I dont think thats a CEL you'd want to turn off.
hmm I come up with: P1312 Exhaust temperature sensor malfunction see this link: http://www.wrxatlanta.com/forums/showthread.php?t=7859&highlight=CEL+codes
I thought it would disable it too. Do you have a stock up pipe? If it is gutted / non stock, you could do the resistor trick where the EGT sensor plugs in. I did that when I changed my up pipe at the same time I got an APv1 (I did it in case I ever went back to stock I wouldn't have to deal with that). Just a thought. Maybe worth a call to Cobb if it is a new unit. I have an extra resistor (I think) if you want it but they are only a couple of dollars at radio shack. For the resistor value check out NASIOC unabombers manifesto in the up pipe section.
not the sort of thing to have come up right when you're about to drive 600 miles... ...so far, seems to have worked.
