P0107 1998 Ford F150 Code - BARO/MAP Sensor Low Voltage Detected
Quick Answer
The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0107 1998 Ford F150 Description
The MAP sensor wiring includes 3 circuits. The Engine Control Module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.
Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the MAP Sensor voltage is less than 0.15 V for greater than 13 ms.
What are the Possible Causes of the DTC P0107 1998 Ford F150?
- Faulty Manifold Absolute Pressure (MAP) Sensor
- Manifold Absolute Pressure Sensor harness is open or shorted
- Manifold Absolute Pressure Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0107 1998 Ford F150?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
