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
