P1464 on 2015-2024 Ford Edge (SE, SEL, Titanium) — A/C Demand Out Of Self-Test Range
1 vehicles · 1 makes · $250-$1,600 repair
Most Reported On
P1464 is an OBD-II diagnostic trouble code meaning “A/C Demand Out Of Self-Test Range.” Ford-family manufacturer-specific code set during PCM self-test. The PCM expects the A/C request (A/C demand) input to be OFF while a Key On Engine Off (KOEO) or Key On Engine Running (KOER) self-test is run. P1464 sets when the PCM sees an A/C or defrost request active during that self-test, or an out-of-range signal on the A/C demand circuit. It is most often simply a procedural fault — the climate control was left on during the test — but it can also indicate a genuine A/C request circuit or pressure-switch fault. Note this is not a turbocharger or wastegate code, so the catalogue issue citing it (Ford Edge 2.0L EcoBoost wastegate actuator) does not match its actual meaning. This code is most commonly reported on 2015-2024 Ford Edge (SE, SEL, Titanium), with repair costs ranging from $250 to $1,600.
