DTC P2199-00: IAT Sensor No.2 Circuit Range/Performance Problem: Notes

DETECTION CONDITION AND POSSIBLE CAUSE

DTC P2199:00	IAT sensor No.2 circuit range/performance problem
DETECTION CONDITION	IAT sensor No.1, IAT sensor No.2 and ECT sensor No.1 are compared after the engine is started and correlation error occurs. *: Ignition switch on when 6 h or more has passed since the ignition was switched to off. Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. PENDING CODE is available 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.
