Baro (Barometric Pressure) - Ford 6.0L POWER STROKE Service Procedures And General Diagnostics

Baro (Barometric Pressure)

• The BP sensor is a three (3) wire
variable capacitance sensor.
• The PCM supplies a 5 volt
reference signal which the BP
sensor uses to produce a linear
analog voltage signal that indicates
pressure.
• The primary function of the BP
sensor is to provide altitude
information so that the PCM can
adjust timing, fuel quantity, glow
plug on time, and VGT control.
