PINPOINT TEST DS: Air Conditioning Pressure (ACP) Transducer Sensor: Introduction
WARNING: This page does not describe the selected car, but rather 35 other vehicles, including the 2007 Mercury Mountaineer, 2007 Mercury Monterey, 2007 Mercury Montego, 2007 Mercury Milan, and 2007 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.
This pinpoint test is intended to diagnose the following:
- ACP transducer sensor (19D594)
- harness circuits: ACP, VREF, SIGRTN
- powertrain control module (PCM) (12A650)
