Engine Check Error - Extreme Hot Engine

[athlon64]

your IAT is located along the intake air duct it will have two wires RED-YEL and GRN-YEL
your HO2S wiring is behind the radiator on the exhaust manifold just upstream from the catalytic converter, it will have four wires WHT, RED, LT GRN, and RED YEL

On four wires, which 2 are resistance wires?
