Default P1312 and P1420?

Got a CEL and went to autozone to have them read. Threw these two codes and not sure excactly what it would be. I did a search and the P1312 came up seems like most people would just clear them and it wouldnt come back, but i couldnt find any solutions to the P1420. Car still runs fine doesnt seem like anythings wrong. Just wanted to make sure. I tried to have her clear the code to see if it would come back but apperently its illegal for them to clear it idk

P1312 - Exhaust Temp sensor malfunction

P1420 - Fuel tank pressure control solenoid high input

What do you guys think?

Your EGT sensor is very important, and if it was burnt out, you would get the malfunction code. Soon your car will enter limp mode and will barely run. Watch out it doesnt happen when your far from home.


The other code I dont know, Ive never had it.


If your EGT sensor is ok, then you need to clean your MAF and make sure its installed correctly.

I did however notice your upgrades, which means your probably tuned which would eliminate any EGT codes as you do not have any cats... or do you?

Ask your tuner if he elimnates EGT codes.. check the wires coming off the EGT to see if it has melted anywhere.

No cats at all, i checked the probe the other day and didnt notice any melted wires

Im wondering maybe if it could be spark plugs, ill be honest i havent changed them in a while and just read meth eats spark plugs apperently idk?

I think im going to do that 2.2ohm resistor mod to the egt probe to eliminate it all together,
