P00CEIntake Air Temperature Measurement System - Multiple Sensor Correlation Bank 1

P00CE indicates that the engine control module (ECM) has detected an implausible relationship between multiple intake air temperature (IAT) sensor signals on bank 1, meaning the readings from two or more sensors that should track closely together differ by more than the calibrated threshold. The ECM monitors these sensors to ensure the intake air temperature measurement is reliable for fuel delivery and emissions control.
