RAIL PRESSURE SENSOR
CIRCUIT
(Fuel rail pressure sensor “A”
circuit)
• 1.DEF: VOLTAGE TOO LOW
• 2.DEF: VOLTAGE TOO HIGH
• 3.DEF: ABOVE THE MAX
LEVEL
• An excessively low voltage from the
sensor is sent to ECM.
• An excessively high voltage from the
sensor is sent to ECM.
• An improper voltage signal from sen-
sor is sent to ECM.
• Harness or connectors
(Fuel rail pressure sensor circuit is open or
shorted.)
