Detroit DD15 GHG14 (2014-16) Fault Code: SPN 164 FMI 3 (MCM) Fuel Rail Pressure Sensor Circuit Failed High (Open Circuit)

DESCRIPTION:
Fuel rail pressure sensor circuit failed high.

MONITORED PARAMETER:
Fuel rail pressure sensor.

TYPICAL ENABLING CONDITIONS:
Always enabled

MONITOR SEQUENCE:
None

EXECUTION FREQUENCY:
Always enabled

TYPICAL DURATION:
2 seconds

DASH LAMPS:
1. MIL
2. CEL

ENGINE REACTION:
Derate 25%

VERIFICATION:
Engine Idle: One minute.

NOTE: If codes for both the intake manifold pressure/temp sensor are active at the same time, repair the circuit between pins 58 or 102 of the engine ECM 102-pin connector and pin 2 or pin 4 of the intake manifold pressure/temperature sensor.

PROBABLE CAUSES:
1. Fuel rail pressure sensor connector/harness.
2. Fuel rail pressure sensor.
3. Intake manifold pressure/temp sensor.
4. Intake manifold pressure/temp sensor harness/connector.
