PINPOINT TEST E: Manifold Absolute Pressure (MAP) Sensor: Introduction
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Ford RV Cutaway, 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
This pinpoint test is intended to diagnose the following:
- Harness circuits: MAP, SIGRTN, and VREF
- MAP sensor
- Powertrain control module (PCM) (12A650)
