P1464 on Ford
A/C Demand Out Of Self-Test Range
P1464 on Ford vehicles indicates a/c demand out of self-test range. Au7o has documented this code across 1 Ford model — most commonly on Edge. 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. Typical repair costs on Ford range from $250 to $1,600, depending on the specific model and root cause.
Common Causes of P1464
- •A/C or defrost left switched on while the KOEO/KOER self-test was performed
- •A/C demand circuit shorted to power, keeping the request signal active
- •Failed A/C pressure switch (cycling or high-pressure switch) or refrigerant pressure out of range
- •Failed A/C request switch or climate control head
- •Wiring / connector fault in the A/C demand circuit to the PCM

- 2.0L EcoBoost Turbocharger Wastegate Actuator Failure and Linkage Rattle2015-2024
The 2.0L EcoBoost uses an electronic wastegate actuator on the turbocharger. Two related failures show up repeatedly: the actuator rod's retaining e-clip goes missing or the linkage works loose, producing a metallic rattle from the turbo area at idle and light throttle; and the electronic actuator itself fails or sticks, so the PCM cannot hold commanded boost and sets an underboost or actuator-performance code with a noticeable flat spot under acceleration. On 2019-2021 Edges the wastegate actuator fault often surfaces as P1464, a code whose description misleads shops toward the A/C system. Left alone, a flapping wastegate flap wears its bushings and eventually requires the whole turbo.

What does P1464 mean on Ford?▼
P1464 stands for "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. On Ford specifically, this code is documented across 1 model.
