P00CE Intake Air Temperature Measurement System - Multiple Sensor Correlation Bank 1
Multiple intake air temperature sensors on bank 1 disagree beyond plausible limits. The intake air temperature sensor feeds the ECM's density calculation — a drifted reading miscalculates fuel mass and pushes mixture lean (cold reading) or rich (hot reading).
Is it safe to drive with P00CE?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
