DTC P0113:00

IAT sensor No.1 circuit high input
DETECTION CONDITION
•  The PCM monitors the IAT sensor No.1 signal. If the PCM detects that the IAT sensor No.1 voltage at the PCM terminal 2Y is above 4.51 V for 5 s, the PCM determines that the IAT sensor No.1 circuit has a malfunction.
MONITORING CONDITIONS

―  0.5 s have elapsed after the ignition was switched ON (engine off or on)
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
