DTC P1469 meaning

DTC P1469 refers to a diagnostic trouble code indicating that the A/C demand is out of the self-test range. This code is typically triggered when the vehicle’s onboard diagnostic system detects an inconsistency in the air conditioning system’s performance during a self-test procedure. The A/C system is crucial for maintaining cabin comfort, and this code suggests that there may be an issue with the A/C control module or related components.
