Codes p0097 p00f5 p0172 and p2199, replaced MAF with non oem (gonna get OEM replacement). Code reader says IAT sensor 2 and sensor 1/2 correlation. Mine has the 2.4 liter non turbo engine, so there is only one IAT sensor according to my research. My (Cheapo) code reader is displaying IAT(F), IAT11(F) and IAT12(F). IAT 12 shows up about 20 degrees warmer than IAT, but as soon as the engine is shut off, the temperature on IAT12 drops to -40 degrees. (Code reader is a FOXWELL) What is IAT 11 and IAT 12 referring to? Do i need a firmware reload to tell the ECU that there is only one sensor? Hopefully a OEM MAF fixes this, but im doubting it. Thanks in advance!
