Check Engine light: code reads p1464:00

[safetygoggle]

Howdy, light came on and the local mechanic pulled P1464:00 using an OBD scanner. Something about the A/C, but he didnt have a clear way to diagnose it. so he cleared it - no cost to me.

Trucks is a 2023 ecoboost AWD.

I've had the check engine light on and off this winter. Could it be caused by temperature swings or something more costly?

if it keeps coming back, will likely take it to the dealer.

Any recommendations or experience with this code? Thanks!

No idea, but according to google AI:

A Ford code P1464 indicates that the powertrain control module (PCM) detected the air conditioning (AC) demand signal was on during the initial EVAP self-test, which is often caused by a faulty evaporator temperature sensor, low refrigerant, or a bad AC pressure switch. It essentially means the AC system's electrical inputs are preventing the computer from properly testing the emission system
