DTC P0112:00: Notes

DTC P0112:00	IAT sensor circuit low input
DETECTION CONDITION	The PCM monitors the IAT sensor signal. If the PCM detects that the IAT sensor voltage is below 0.16 V for 5 s , the PCM determines that the IAT sensor circuit has a malfunction. Diagnostic support note This is a continuous monitor (CCM). The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	MAF/IAT sensor connector or terminal malfunction Short to ground in wiring harness between MAF/IAT sensor terminal D and PCM terminal 1AT PCM connector or terminal malfunction Short circuit in IAT sensor signal circuit and ground circuit each other IAT sensor malfunction PCM malfunction
