Default noob egt sensor question

hey everyone, my car threw a p1312 cel a few days ago. autozone said it's a bad egt sensor. my question is, do i have more than one egt sensor? ive got a 2004 wrx with an sti up pipe, so i dont even have an egt in the up pipe. is there one in the exhaust?

i also noticed that some people were saying that a p1312 is a misfire code. did they change the code from year to year?

mods are: cobb intake, sti uppipe, helix bellmouth downpipe, greddy evo2 exhaust. tune.

P1312 Exhaust temperature sensor malfunction

there is only 1 stock EGT - if you have a catless uppipe w/o EGT you need to do the '2.2kohm resistor mod' - basically you fake a normal EGT thermistor reading using a 2.2k resistor in the harness - search or read the Exhaust / Uppipe FAQs for more detailed instructions

perhaps you had a resistor fitted but it's recently fallen out

afaik missfire codes are all low 3xx not 13xx

something just occured to me, when i had my car tuned we erased the cel code that resulted in not having an egt sensor. that way i never needed to mess with the 2.2k resistor mod. what else could be causing this?

for those interested, the problem has been solved. it turns out that with an open ecu reflash, the egt sensor error can creep back. solve it with the 2.2 ohm resistor mod.
