Unhappy Need HElp! Check engine code P0545

My car is running with a straight pipe , cold air injen intake, Sqqbv , resistor for the rear O2. My car was running fine. esle for the backfires .. couple weeks after i install my upipe and downpipe.. when i boosted my car pretty hard.. a check engine came on. I scan it.. codes came out
P0102a MAF?VAF ciruit low input, P1301 Mfr ctrlled Ign or Misfire,
P0113 IAT ciruit High Input, P0545 Exhaust gas Temp sensor Ckt low,
P1544 Mfr Ctrl Veh spd, Idle Ctrl, Aux Inp

So i clear the codes, and cleaned the MAF. engine was off, later that day i boosted again.. CHECK ENGINE CAME BACK ON. this time
P0545 exhaust gas Temp sensor Ckt low. was the first code.
what could be the problem with this code.. my car has about 63,000 miles 2002 wrx .. i think i might need a new gas temp sensor.. or clean it some how.. or maybe some other problem that cause it?? or do i need a resistor for the gas temp or something?? i dunno

do you have the resistor in the EGT circuit? it is the sensor in the up-pipe that reads exhaust gas temp. if it isnt resistored it will throw a code. cannot recall the code right now, however it is related to the sensor in the up-pipe not reading the cat that was there. could be the airflow through the up-pipe is fast enough from prior ECU settings that it is throwing as code for too cool a temp in the exhaust at high rpm, high boost situations

No resistor in EGT. . i am surpose to put a resistor in EGT after replacing the cat-ed up-pipe?? .. if so where can i get one of this resistor..

Radio Shack

2.2k ohms 1/2 watt resist ... don't have the part # but they come in 5 packs. Just put one in the EGT probe wiring harness, loop it.

If they are running an uppipe with an EGT probe, a m12x1.25 25mm fits the bung. Most of them I do still have an aftermarket UP with the probe in. You need those to remove it.
